HONG KONG 1973

GENERAL

INTRODUCTION

1.01 The Colony of Hong Kong has an area of approximately 400 square miles and a population of about 4,000,000. The bulk of this population is concentrated in a very intensively developed area of some nine square miles covering the Northern shore of Hong Kong Island, the Kowloon Peninsula and New Kowloon from Lei Yue Mun in the East to Lai Chi Kok in the West. The new town of Tsuen Wan in the New Territories, a few miles to the North-West, continues to develop rapidly and Castle Peak (to be known in future as Tuen Mun) New Town, near the Western extremity of the mainland, is also grow- ing fast. The extent of these urban concentrations is shown on the frontispiece map.

1.02 The reported cost of private building work completed during the year amounted to $1,272 million, an increase of about 28% com- pared with the 1971-72 figure of $991.2 million. It is of interest to note that while this figure surpasses that of $1.058 million in 1966 when the building boom was at its summit, the actual volume of build- ing is probably less due to higher prices. The high level of activity in private building development continued without any indication of a decline and, in fact, towards the end of the year there was a marked increase in the submission of plans for approval. As the staff of the Buildings Ordinance Office were heavily engaged in emergency works immediately after the rainstorms in mid-June in connection with dangerous buildings and later in closer inspections of works-in- progress the processing of plans was delayed and the backlog con- tinued to increase throughout the year.

1.03 At a ceremony on 25th October, 1972 H.R.H. Princess Alexandra, G.C.V.O., officially opened the Hong Kong Government South Kwai Chung Jockey Club Clinic. This clinic includes a Maternity ward and, in a separate block, a chest clinic.

1.04 The Sheung Kwai Chung Government Secondary Technical School was opened by the Hon. T. K. ANN, O.B.E., J.P. on 7th

November, 1972. The design of this school is a repeat of the Kwun Tong and North Kowloon Secondary Schools. It includes twenty-one teaching classrooms, eleven specialist classrooms for science and technical subjects, an assembly hall, a library and an administrative office.

1.05 On 16th November, 1972 the Medical Department Laundry at Shau Kei Wan was officially handed over. This laundry serves all Medical and Health Department Institutions on Hong Kong Island and eventually will serve some on the Mainland.

1.06 Fan Ling Recreation Ground Stage I was officially opened by the Director of Building Development on 19th December, 1972. This recreation ground, which has floodlighting facilities for night use, includes two basketball courts, a badminton or volley ball court, and a full sized football pitch with seating for 500 spectators. There is also a roller skating rink, a service building with changing facilities and a rest garden with a refreshment kiosk. The ground is one of a series which is being provided in the New Territories.

1.07 Despite staff shortage and adverse weather conditions en- countered during the first half of the year good progress was achieved on the majority of highway projects.

1.08 On Hong Kong Island, the two flyovers linking Upper Albert Road with Cotton Tree Drive and Kennedy Road were opened to traffic. Widening of Connaught Road Central between Murray Road and Morrison Street was completed. Traffic flow in the Central and Mid-levels area was thus significantly improved. The Pokfulam Road/ Bonham Road/Hill Road junction was improved with the completion of a one-way flyover from Pokfulam Road to Bonham Road and the associated road widening. In Kowloon, most of the projects forming part of the Kowloon foothill road linking Kwun Tong with Kwai Chung were commenced and progress has been stisfactory.

1.09 The Cross Harbour Tunnel road connections on both sides of the harbour were completed in time for the opening of the Cross Harbour Tunnel in August. This was commemorated by Her Royal Highness Princess Alexandra, G.C.V.O., unveiling a plaque on 21st October and in November 1972 representatives from Government Departments and Divisons of the Public Works Department involved in the cross-harbour tunnel project were satisfied that all major works were completed satisfactorily. A final certificate of completion was

then issued by the Director of Public Works in accordance with Section 31 of the Cross Harbour Tunnel Ordinance (No. 28 of 1969).

1.10 The problem of pedestrian traffic was energetically tackled and a comprehensive programme for the construction of footbridges at various locations was formulated. Detailed structural designs for some of these footbridges were undertaken. Two footbridges, one over Choi Hung Road and one over Princess Margaret Road, were completed for the use of pedestrians.

1.11 As a result of increase in car ownership, traffic congestion and shortage of parking spaces continued to be a problem. Traffic manage- ment techniques continued to be applied in order to extract maximum capacity from the existing road network.

1.12 Large-scale site formation and reclamation continued and a total of 124 acres of land was formed on Hong Kong Island and in Kowloon and the New Towns in the New Territories. A start was made on Stage V of Central Reclamation on Hong Kong Island.

1.13 Investigations for a number of pollution-control projects were in progress. These included the provision of complete sewage treatment for north-west Kowloon and Sha Tin, the building of additional refuse incinerators and the opening of sites for the controlled tipping of refuse. A special study on pollution aspects of a proposed oil re- finery on Lamma Island was well advanced.

1.14 Further designs for the private developers' proposals for the three container-terminal lots at Kwai Chung were approved; two berths were brought into use while the third was well advanced.

1.15 At Kai Tak Airport, overlaying the existing runway with a new surface and work on the road tunnel under the Airport com- menced while extension of aircraft parking aprons and taxiway facilities continued. Reclamation for the 2,530-foot runway extension was completed and the construction of breakwaters between it and Kwun Tong, to form a typhoon shelter, commenced.

1.16 Work continued on the new railway terminus at Hung Hom, where track-laying and construction of a podium over the tracks and of buildings at track level were in hand.

1.17 To implement further Government's policy on private quarry- ing, tenders were called and a contract signed for the right to quarry stone on a large scale at Cha Kwo Ling for ten years from mid-1974.

1.18 Although rainfall was above average the wet season ended with a storage position in relation to demand only slightly more favour- able than the previous year's. A continuous 24 hour water supply was maintained throughout the year.

1.19 Work continued on the construction of access roads and the tunnels and intake complex for the High Island Water Scheme. The contract for the 60,000 million gallon reservoir works was awarded and work commenced. Scheduled progress was maintained on the raising of the Plover Cove dams and the extension of Sha Tin treatment works and Tai Po Tau pumping station. Contracts were awarded and work was well in hand for the site formation, marine and general civil engineering works for the 40 million gallons per day single purpose desalting plant. Supply and erection of the plant proper was con- tracted to a manufacturer in Japan, where fabrication started.

ORGANIZATION

1.20 The Department combines many functions which in other territories would be undertaken by a number of agencies viz:

Building

(a) The design and construction of Government

buildings

(b) The control of private development

Engineering (a) Civil Engineering

Land

Water

(b) Highway Construction and Traffic Engineering (c) Electrical and Mechanical Engineering (d) Railway Engineering including the Mass Transit

The disposal of Crown land

(a)

(b) Land Surveying

(c) Town Planning

(a) Design and construction of traditional impound- ing and purification works together with desal- ination plants and the distribution and sale of fresh and sea water.

The organization chart showing the division of the Depart- ment into a Headquarters, seven Offices, the New Territories Develop- ment Department and the Mass Transit Department is on page viii. The object of the organization is to decentralize wherever possible so

Digitized by Google

that day-to-day decisions on virtually all matters, other than depart- menal policy and the programming of future projects, can be made by Offices. Headquarters concerns itself with departmental policy, future works programmes and the co-ordination of the needs of Offices. To provide this co-ordination, weekly meetings are held at which Headquarters and Office representatives consider matters affecting land and development. Very close contacts are maintained between P.W.D. Headquarters and the Colonial Secretariat.

THE EFFECT OF VACANCIES ON PRODUCTIVE EFFICIENCY

1.22 To a greater or lesser extent all Offices of P.W.D. continue to work below strength, especially at the professional/assistant pro- fessional level and the Buildings Ordinance Office in particular has been 43% and 40% below approved strength in respect of building surveying and structural engineering staff. In other offices the deficiency varies from 15% to 28% in professional grades of various disciplines and up to 35% in technical grades.

1.23 Recruitment has marginally improved the position in some disciplines but in others, recruitment exercises have failed to keep pace with normal retirement and other wastage. This is particularly the case in those disciplines which produce few qualified local officers, notably quantity surveying, as the cumbersome procedures involved in recruiting expatriates, combined with the unsatisfactory accommoda- tion situation, have deterred many potential candidates.

1.24 The general effect of these vacancies is to delay Government projects and despite the employment of private architects, quantity surveyors and consulting engineers this situation appears likely to continue. Some facets of work, especially in the Buildings Ordinance Office, have had to be curtailed or discontinued in order to concentrate on more essential duties.

STAFF

1.25 The total staff numbered more than 12,100, of whom 865 were professional or assistant professional officers. Occupants of susperscale posts, distribution of staff and rates of pay of artistans, labourers and apprentices are given in Appendices A, B and C respectively.

1.26 During the year the following senior officer left Hong Kong on leave prior to retirement:

Mr. R. C. CLARKE, Director of Lands and Survey, on 1.6.72.

TRAINING

1.27 Training facilities continued to be provided for technical and assistant professional staff. Altogether 19 Apprentices, 222 Craft Apprentices and 77 Technical Apprentices, who had signed agree- ments to follow a course of instruction over a period of four or five years, were being trained part-time in the Waterworks or Mechanical Workshops and part-time at the Polytechnic/Morrison Hill Technical Institute.

1.28 A total of 37 engineering graduates from the University of Hong Kong were on indenture to the Director of Engineering Develop- ment as Apprentice Engineers to gain some of the experience required for the professional interview of the Institution of Civil Engineers. Four Apprentice Architects, four Apprentice Electrical Engineers and seven Apprentice Mechanical Engineers were also under training.

1.29 The Principal Government Land Agent undertook the training of 18 Surveying Assistants (Land) and 28 Surveying Assistants (En- gineering).

1.30 During the summer vacation, 28 students from the University of Hong Kong were attached to this Department. Five were attached to the Architectural Office, 14 to Civil Engineering Office and Highways Office, three to Waterworks Office and six were given instruction in the Electrical and Mechanical Office.

1.31 Altogether 47 officers of the Department were on, or com- pleted, courses during the year in Britain, Australia or the United States of America. Some of these courses were taken while the officers were on vacation leave.

1.32 Further details of training are included in the sections dealing with individual offices.

ACCOUNTING SERVICES DIVISION

Chief (Principal) Treasury Accountant:

K. W. CATTON

Principal Treasury Accountant (Acting):

P. M. CARR (21.4.72-15.9.62)

Organization

21.16 During the year the post of Principal Treasury Accountant was retitled Chief Treasury Accountant.

2.17 Little further progress was made in the development of depart- mental accounting services. A report on the Architectural Office con- taining recommendations for the establishment of additional accounting posts has been with the Treasury since April 1972. During this time the department was requested to supply further information, but the Treasury, because of other priority assignments, are not in a position to examine the staffing proposals made.

2.18 The ever increasing volume and complexity of the work of the Architectural Office gives rise to growing concern over the problems of controlling and accounting for expenditure in that Office.

2.19 The post of Treasury Accountant, Electrical and Mechanical Office, which has been vacant since May 1970, remains unfilled.

2.20 However, the mechanization of the workshops costing system, which received detailed study over many months, led to joint proposals by two companies marketing accounting machines and computer equipment.

2.21 The proposals were receiving further study when a decision was taken to conduct a department-wide computer feasibility study. In consequence no further progress can be made towards the introduc- tion of a mechanized/computerized costing system, until the feasibility study is completed.

12

2.22 In the meantime, the manual costing system will continue to operate but with its known limitations. This means that, some seven years after the publication of the 'Report of the Working Party on Vehicle Workshop Facilities,' the main purpose of establishing a costing system, i.e., to measure workshop efficiency in relation with operating costs, has still to be realized.

2.23 A draft report on the reorganization of accounting services in the Highways Office is receiving departmental study. This Office also requires a substantial increase in the number of accounting posts to bring accounting services up to an acceptable standard of efficiency.

Expenditure

2.24 Departmental expenditure for the year ending 31st March, 1973, including that incurred on behalf of the armed forces, amounted to $1,234,857,390, exceeding the highest annual expenditure ever re- corded, last financial year, by $338,006,882 or 37.68%. This expenditure represents 28.72% of the total Government expenditure for the 1972-73 financial year and maintains the Public Works Department in its posi- tion as the largest spending department in Government.

2.25 As may be seen from the comparative analysis of expenditure at Appendix F there have been substantial increases in nearly all classes of expenditure and these are reflected also in the number of payment vouchers examined and passed for payment. There were 20,998 of these as against 20,488 in the previous year.

Head 62-Public Works Department

Personal Emoluments

2.26 There was a further increase in the approved establishment of the department, which rose to 14,951 from 13,778 in the previous year. The resultant expenditure was $180,169,885 or 14.59% of total de- partmental expenditure, which exceeded the approved estimate of $179,000,000 by $1,169,885 and showed an increase of $33,251,166 or 22.63% over the previous year's expenditure.

2.27 The amount of overtime worked during the year was mar- ginally lower than that for 1971-72; claims processed totalled 63,923, representing 2,070,184 hours or 258,773 man days. However, total expenditure on this account rose from $9,178,816 to $12,734,005, this

being mainly attributable to the increases in hourly rates and the payments of adjustments during the year.

Other Charges

2.28 Departmental expenditure under 'Other Charges-Annually Recurrent' increased by a further $1,550,271 or 31,20% to $6,519,049. The revision of salary for Apprentice Engineers and Apprentice Archi- tects, rent for Architectural Office Maintenance Division in Asian House and rise in daily labour expenditure in the Electrical and Mechanical Office largely accounted for this increase.

2.29 There was a continuing requirement for officers to use their private vehicles for duty journeys and 8,506 claims for mileage allow- ance were processed during the year resulting in the expenditure of $1,755,017. The increase in expenditure over 1971-72 is due to increases in rates and mileage covered.

Head 63-Public Works Recurrent

Buildings and Lands

2.30 Recurrent expenditure showed a further increase during the year to a total of $42,998,067, as compared with $30,141,997 in 1971-72, divided among the Offices concerned as follows:

(a) Architectural Office

(b) Buildings Ordinance Office

(c) Crown Lands and Survey Office

1971-72

1972-73

27,776,967

34,572,206

11,009

3,311,672

2,354,021

5,114,189

These increases were respectively due to:

(a) the rise in contract rates, increasing number of buildings to be maintained and the raising of the limit from $40,000 to $75,000 on 'Alterations and additions to buildings' with effect from 1st April, 1972;

(b) the recovery operation mainly required for the Po Shan/Kote- wall Road disaster area in the June rainstorm, the costs of which were charged to 'Emergency works under the Buildings Ordinance';

(c) the additional clearance and fencing work required in connection with the 'Keep Hong Kong Clean' campaign and the payment for the demolition of illegal multi-storey buildings on the periph- ery of Kowloon Walled City.

Civil Engineering and Highways

2.31 The responsibilities of Civil Engineering Office and Highways Office overlap to a certain extent, particularly in the field of drainage works, and for ease of comparison the expenditure figures have been taken together in the table at Appendix F. The combined recurrent expenditure of the two Offices for 1972-73 is $74,461,786 divided as follows:

Civil Engineering Office Highways Office

$27,161,821

$47,299,965

The total exceeds the 1971-72 figure of $48,210,933 by $26,250,853 or 54.44%, of which $23,435,229 represents the cost of remedial works following the severe rainstorms during the year.

Electrical and Mechanical

2.32 The Electrical and Mechanical Office has the largest work force in the Public Works Department with a total establishment of more than 4,400. This Office is responsible for the maintenance, servicing and repair of the Government vehicle fleet, together with all electrical, mechanical and air-conditioning plant and equipment other than that contained in waterworks projects and certain building services.

2.33 The expenditure incurred in discharging these responsibilities amounted to $12,705,914 in 1972-73 compared with $12,486,206 in the previous year. Furthermore, expenditure arising from the Office's responsibilities under the Defence Costs Agreement amounted to $2,632,039 excluding personal emoluments. This considerable increase in expenditure compared with the previous financial year's total of $1,761,603 was principally because of the expansion of the work force, which brought about a higher output in the workshop. The other factors were the increase in the cost of electrical and mechanical spares and the very much higher contract rates for vehicle body building and other works.

Waterworks

2.34 Expenditure incurred during the year by the Waterworks Office on the operation and maintenance of the water supply system amounted to $60,449,676 as compared with $48,732,255 in 1971-72, The increase is mainly attributable to the cost of extra amount of water drawn from China in July and August 1972, the revaluation of the R.M.B. relative

15

to the Hong Kong Dollar and the additional repair works caused by the heavy rainstorm.

Heads 64-67--Public Works Non-Recurrent

2.35 All Heads showed substantial increases in expenditure over the previous year. The total expenditure under all four Heads in 1972-73 was $773,348,151 which was $239,965,163 or 44.98% higher than in 1971-72. The increase reflects a continuing expansion of the Public Works Programme and higher construction costs resulting from increases in wages and the price of materials.

2.36 The summary at Appendix G provides a comparison of the actual expenditure under each Head with the approved estimates broken down over the main project groupings.

Expenditure Summary

2.37 The following comparative statement, illustrated graphically at Appendix D, summarizes public works expenditure (excluding military works) over the ten year period from 1963-64 to 1972-73.

Department and H.B.M. Department of the Environment under the Defence Costs Agreement with the United Kingdom Government.

Military Works and Services

2.38 Under the 1971 Defence Costs (Works) Agreement the Public Works Department is required to undertake all maintenance works and services in Military Establishments throughout he Colony as well as the design and construction of new capital projects for the three Services.

2.39 The cost of all maintenance and minor work services is borne by the Hong Kong Government whilst major capital works costing £5,000 and over are charged against the Hong Kong Government's total agreed capital works contribution of £17M, ($247.35M), for the five-year period of the agreement.

2.40 As shown in Appendices I and J the expenditure on main- tenance, new services minor works and capital works for the year 1972-73 amounted to $73,546,589 which represents an increase of 14.8% over the previous year.

Revenue

2.41 The revenue collected by the department during the year totalled $849.970M compared with $433.272M in the previous year. A comparison between the amounts collected in each of the two years on the main items of revenue is provided by the following table:

Revenue from land sales continued to increase and indicated the prosperity of the local property market while the collections derived from quarry products and works executed on private account reflected the growth of building development. As a result of the implementation of the new Defence Costs Agreement, no revenue from ‘Services Capital Works' and 'Services Maintenance Charges' became due. Although revenue collected under 'Chargeable Water' showed an increase of $23M over the previous year, it was under the approved estimate by nearly $20M due to the implementation of the 4 months' billing system and the consumption by new meters not yet taken into account in the year under review.

Deposit and Suspense Accounts

2.43 The volume of work of various types carried out by the Department for private organizations and individuals showed a further increase in 1972-73 as reflected in the respective deposit accounts. Payment in these cases is required in advance, based on an estimate of the cost of the work to be done, to which is added a percentage to cover the departmental overhead expenses; amounts thus received are placed on deposit accounts until the work is completed and the final cost is known, when an adjustment is made taking the equivalent of the actual cost plus departmental expenses to revenue, any surplus held being refunded to the payer. At the beginning of the year the balance held on deposit, i.e. in respect of works not completed, was $9,133,587 and further deposits amounting to $11,493,192 were received during the year; from this total of $20,626,779 the amount taken to revenue in respect of completed works was $7,863,619, while $1,289,315 was refunded, leaving balances remaining on the deposit accounts at the end of the year totalling $11,473,845.

2.44 Under the Government-financed Staff Welfare Scheme, funds allocated by Government are placed in a departmental deposit account to be used for authorized welfare and relief purposes to assist lower- paid staff. During the year 22 loans totalling $14,830 were issued under the scheme and $8,657 was recovered in repayments. The balance avail- able at the end of the year for all purposes was $68,756.

2.45 During the year, the transactions under the Suspense Account --Colonial Treasurer Incorporated-were less than expected and the amount involved was minimal. No properties were taken over by the

18

Colonial Treasurer Incorporated but it is expected that transactions in the coming financial year will increase.

Contracts

2.46 At the beginning of the year there were 300 capital works contracts in progress and a further 376, with a value of $1,620.076M, were awarded during the year; of this combined total of 676 contracts, 424 were still uncompleted at the end of the year. Three surety bonds were called in but still unpaid during the year, although $129,214 was recovered from sureties in respect of bonds called in during 1971-72.

2.47 No contract was re-entered during 1972-73, which may be attributed to the inclusion of wages and prices fluctuation clauses in the General Conditions of Contract. The practice of inspecting con- tractors' accounts in order to assess their financial stability continued and during the year 54 sets of accounts were examined. Of these 11 were eventually considered to show insufficient resources to support the applications for inclusion, confirmation or promotion in the P.W.D. list, while 43 cases were approved.

Supplies

2.48 The Supplies Officer, Public Works Department Headquarters, continued to carry out programmed stores inspections of 17 allocated stores in Public Works Department and, where necessary, give advice to professional and technical officers as well as supplies personnel on procurement and storehouse operation procedures.

2.49 During the year under review, 107 cases of lost or deficient stores under S.R. 394 (a) - (e) were reported by various offices of Public Works Department and the total value of losses written off was $18,219.47 compared with 130 cases valued at $21,145.49 for the previous year.

2.50 The Annual Departmental Stocktaking under S.R. 391 was conducted on 72 stores locations within Public Works Department, resulting in 60 discrepancies being found. The surpluses and deficiencies were subsequently adjusted or written off.

2.51 A total of 220 orders for B.S.I. publications and technical books were placed by the Public Works Department Headquarters Supplies Section during the year, at a total cost of $76,998.58 compared with 97 orders at a total cost of $38,594.72 during the previous year.

TECHNICAL AUDIT

Chief Technical Examiner:

D. M. HARDING, F.R.I.C.S., F.I.Q.S., A.I.Arb.

P. FRENCH, A.R.I.C.S. (Acting 1.6.72-22.11.72)

2.52 The sixth year of this Unit was one of change in direction. Routine Audit of the Department's construction contracts and pro- cedures continued only up to November, when a policy change substan- tially replaced Audit by a programme of Investigations and Reports on Selective Audit Studies covering any matter within the Department which relates to the effective use of the Department's resources of staff, equipment and money, However, routine audit of contracts was to continue as well but on a small scale.

2.53 A Programme of Work for T.A.U. was agreed and a start was made on the Reports. One on Financial Status of Contractors' is under way.

2.54 Recruitment exercises for overseas professional staff con- tinued, resulting in one Technical Examiner arriving in November. This offset the departure of one Technical Examiner who returned to his U.K. Home Establishment (D.O.E.).

2.55 The vacancies for professional staff in the Unit therefore remained at 25% throughout the year.

EXECUTIVE UNIT-METRICATION

Metrication Officer:

D. NEWBURY

Introduction

2.56 H.E. the Governor established a Metrication Committee on 15th May, 1970, representative of Government and the private sector.

2.57 The Committee's terms of reference required it to consider the implications for Hong Kong of the increasing world wide use of the metric system, to advise the Governor on the necessity and timing of a change to the metric system in the different sectors of the economy including Government and to guide and keep progress under review and to make recommendations on such legislation as might be necessary.

20

2.58 One of the recommendations from the Committee was, that Government take a firm decision in principle and publicly declare its intent to embark on a programme of metrication in the fields for which it was responsible, with immediate emphasis on the fields of Public Works and Education.

2.59 This recommendation was accepted and in the field of Public Works approval was given for the Building Construction and Civil Engineering Sub-Committee to the Metrication Committee to adopt the role of Public Works Department Steering Committee for Metrication.

2.60 The membership of the Steering Committee included represent- atives of all the P.W.D. offices and representatives from the Hong Kong Institute of Architects, the Hong Kong Branch of the Institution of Structural Engineers, the Building Contractors Association and Hong Kong University.

2.61 To assist the Steering Committee in its work and to effect the proper implementation of its policies, the Director of Public Works sought approval for the creation of the Executive Unit, to be headed by an officer who would be both the Secretary to the Steering Committee and Metrication Officer to the Public Works Department.

2.62 Approval was granted and the Executive Unit was established on 1st June, 1972.

Unit Operations

2.63 The primary task was the formulation of a Target Programme for the metric change within the Public Works Department.

2.64 The Target Programme was published on 30th September, 1972 and determined the sequential progress of the metric change in all offices in three phases, acquisition of data and equipment, training and implementation.

2.65 The major activity in all offiecs was seen to span the period September 1972 to September 1975 with a target data of July 1974, at which time it was considered feasible that metric working would be incorporated in all new P.W.D. projects.

2.66 It was early recognized that the metric change in the private sector would be conditioned by the availability of metric building legisla-

21

tion, and to that end the Director accorded a high priority to this work in the Buildings Ordinance Office.

2.67 The period under review covers the major part of the first phase of the metric change and it can be recorded that the Unit has assisted and directed the acquisition of metrication equipment and data in all offices of the Department. In addition the Unit has itself produced the first three of a series of publicity and visual aids and the first 20 Metric Instructions in a common binding, which will be aug- mented by future Instructions, all of which will be the Department's major source of metric information and metric standards.

2.68 Concurrently the preparatory work for the training phase was also carried forward and the Basic Induction Course will be printed and ready for presentation to all professional and technical staff from May 1973 onwards. Other training aids in course of production in- clude a Desk Top Metric Manual for Secretarial and Clerical Staff, Metrication Notes for Architectural Office and technical notes an other facets of metric working.

2.69 Effective liaison has been achieved with other metrication authorities throughout the world with particular emphasis on the United Kingdom, Australia and Singapore.

INFORMATION UNIT

Principal Information Officer:

D. K. LEWIS, B.A. (Hons.) (Oxon.)

2.70 This Unit was set up within the Department on 4th January, 1973, when the Principal Information Officer arrived on secondment from Information Services Department. The Unit consists of P.I.O., a Shorthand/Audio-Typist, who was assigned to it on 12th March and a Clerk, who was assigned on 22nd January.

2.71 The Unit became operational in stages over the period of the last quarter of the year. By the end of February, P.I.O. had completed a preliminary process of familiarization, had drafted his Terms of Reference and List of Duties, had drawn up an initial programme of work for himself and was engaged in carrying it out.

2.72 During the last six weeks of the year the Unit was dealing with a daily influx of queries and requests coming from the Press and

FORWARD PLANNING

3.01 Normal public works projects take at least 3 years from conception to completion and thus even a scheme which can be con- sidered in isolation must be planned for the conditions which will exist this length of time ahead. Most projects, however, are only part of an overall plan or policy and the Department has to plan far ahead of the present needs in order to make provision for and anticipate requirements in the years to come.

Government Buildings

BUILDING

3.02 The programming of architectural projects, with the exception of maintenance of Government buildings and Government Public Housing, is controlled by the needs of the clients, i.e. other Govern- ment departments, and is limited by Government's financial resources and the work capacity of the Architectural Office.

3.03 The maintenance of Government buildings is the subject of a planned programme and is dealt with in much the same way as it would be by any other good landlord. The normal cycle for complete external redecoration and maintenance is now four to five years although all buildings are surveyed and dealt with on their merits, since some buildings, by reason of their location or usage, require more frequent maintenance than others. Regular surveys are also made to check on incipient defects in the buildings, including electrical and mechanical installations and equipment such as air-conditioning systems and lifts.

3.04 Maintenance work is carried out by maintenance contract which is usually let for a period of three years. This is essential, because the large number of varied buildings involved (and consequently, the range of work required) needs a complex organization by the con- tractor which it would not be economical to set up for a period of one year only. It also, of course, takes time for a contractor to become experienced, and therefore fully efficient, in this type of work.

3.05 Since the introduction of the Mark VII accommodation, the standard of Resettlement housing has been raised to that of Govern- ment Low Cost Housing. A 10-Year Programme combining the two types of public housing to provide accommodation for some 1,800,000 people between 1973-74-1982-83 has been accepted by Government.

:

Public Works Department is responsible for the production of accom- modation for some 558,000 people and the balance of the housing target will be dealt with by the new Housing Department.

Private Building Development

3.06 The principal function of the Buildings Ordinance is to con- sider all plans for private development submitted for approval. Staff requirements to deal with these plans are governed essentially by de- velopment trends and forward planning for the General Division is therefore limited to anticipation based on these trends.

3.07 The comprehensive inspection of works-in-progress carried out by professional staff in the past proves such inspection is necessary to ensure that buildings under construction comply with the Buildings Ordinance. With the likelihood of more recruits at professional level in the coming year, it is possible that inspection of every project under construction can be made in the future.

3.08 At present Engineers in the small Civil Engineering Unit in the Buildings Ordinance Office are all seconded from other offices of the Department. Proposals have been made for setting up a Civil Engineering Division in the Office with adequate staff to carry out all the functions relating to civil engineering aspects.

3.09 In the field of dangerous buildings progress on planned in- spections has been slow. This is mainly due to staff shortages and the effect of the rainstorms in mid-June. The burden on the Dangerous Buildings Division and the Works Division is further increased by the recent growing number of defective drainage complaints, received from the public, which require action of the two Divisions. It is expected that the staff situation may be improved soon and the two Divisions will then be able to carry out all the duties effectively.

ENGINEERING

Highways

3.10 Roads and drainage works are constructed to an overall plan which is developed in three stages:

(a) assessment of the present demand and growth rate,

(b) forward projections to a design year or to the ultimate, and (c) formulation of proposals.

25

3.11 There are 631 miles of roads in the Colony. The total number of vehicles registered on 31.3.73 was 193,434, an increase of 14.1% during the previous 12 months.

3.12 On the average, traffic volume at cordons and screen lines in 1972 increased by 5.6% over the corresponding values for 1971. The highest traffic flow occurred in Prince Edward Road in Kowloon City where the average week-day figure for 1972 was 107,000 V.P.D., an increase of 27% over the figure for 1971.

3.13 The Department commissioned a firm of consulting engineers (Freeman, Fox, Wilbur Smith & Associates) in 1967 to make proposals for the future development of the major road network. Their report was published in 1968. The recommendations contained in this report, together with traffic data from 270 permanent monitoring sites through- out the Colony, are used by the Highways Office to formulate a pro- gramme of construction and improvement giving recommended priorities for works. The programme is revised annually for approval by the Roads Committee and the Transport Advisory Committee, the latter body having both official and unofficial membership.

3.14 Due to rapid change of factors influencing transport demand and travel characteristics, a thorough up-dating of the information given in previous major transportation studies was felt to be necessary and Wilbur Smith & Associates were commissioned on 1st March, 1973 to carry out this updating.

3.15 A 5-year forecast of expenditure, which is updated annually at the start of the financial year, was prepared on the basis of the Road Priority Programme mentioned earlier. The Works Programme of Road Construction and Improvement was sensibly prepared, taking the staff and resources situation into account. This is updated annually and approved by the Public Works Sub-Committee of the Finance Committee at the first of the three review meetings held each year.

Drainage and Water Pollution Control Projects

3.16 A review of the capacity of existing sewer systems has been undertaken to formulate recommendations for improvement works where necessary to cope with development. Sewer gaugings are also being carried out in different types of developments to check the validity of design criteria. A model has been constructed for the study of drainage characteristics of road pavement and the performance of gully gratings pertinent to Hong Kong conditions.

3.17 The final report on the Hygdrological Surveys of Victoria and Tolo Harbours prepared by consulting engineers indicated that pollu- tion levels off north-west Kowloon were critical and would become so in Tide Cove when the Sha Tin New Town is developed unless pre- cautions are taken. Consulting engineers have therefore been employed to carry out detailed study on these areas and to recommend appro- priate treatment and disposal methods. Regular monitoring of harbour waters and bottom sediments continues for obtaining basic informa- tion on the long-term effects of continuous discharge of sewage into the harbours and for assessing the effectiveness of future treatment works. The pilot sewage treatment plant under construction in Shek Wu Hui, when completed, will be operated under varying conditions employing different treatment methods. It is expected that the study will yield information on the treatment method most suitable for Hong Kong.

Port Works and Reclamation

3.18 The planning and construction of seawalls, piers and other marine structures are not normally carried out to a comprehensive programine but undertaken as and when required.

3.19 Reclamation schemes are conceived not only to provide addi- tional land for urban or other development but also to give an outlet for surplus material from private housing schemes and large-scale site formation work. Engineering feasibility studies are carried out to determine the size and layout for larger schemes. The detailed planning and layout of these schemes are prepared in consultation with in- terested Government departments and offices.

Land Development

3.20 Where the formation and servicing of undeveloped areas for urban use involve major engineering works, an investigation into the engineering feasibility of the proposed development is carried out by the Civil Engineering Office. The feasibility reports give details of land formation, population build-up, orders of engineering costs, profit- ability, time required, land clearance problems, main communications, necessary water and other utility services, etc. These investigations are carried out in accordance with a priority programme which is subject to periodic review. The programme stems from an assessment of the demand for land and its proposed use against the background of Government policy and the Colony Outline Plan.

27

3.21 Previous feasibility studies have set the pattern for the develop- ment of new towns at Tuen Mun and Sha Tin, each planned for a population of about 0.5 million people. Studies currently in the pro- gramme include, for example, areas for development such as Tai Hom, the next stage of development in the New Towns of Tuen Mun and Sha Tin, Tsing Yi Island, and areas north of La Salle Road and Tat Chee Avenue as well as many other locations. The accelerated public housing target has caused considerable revision of programmes for the New Towns.

Airport Development

3.22 A 10-Year development plan for Hong Kong Airport drawn up by the Civil Aviation Department provides the overall framework within which detailed planning of works done by the Civil Engineering Office is carried out. Such considerations as the growth in cargo and passenger traffic, aircraft movements and the commercial use of even larger and heavier aircraft are taken into account.

3.23 Work currently in hand on the extension of the runway and aircraft parking aprons will virtually exhaust the physical capacity of the present Airport for major expansion in those respects and with the completion of the planned air cargo complex in a few years time, there will be room only for improvement rather than additional facilities.

Railway Development

3.24 The land at the present time occupied by the Terminus of the Kowloon-Canton Railway at Tsim Sha Tsui is required for more comprehensive development and the Terminus is therefore being re- sited on the Hung Hom Reclamation. A description of the progress of this work is given elsewhere in this report. The new Terminus is expected to become an important centre of communications since it is served by passenger ferries from North Point and Wan Chai, is adjacent to the Kowloon entrance of the Cross Harbour Tunnel, and will be served by buses. It may also, possibly, be served in future by an under- ground railway line.

3.25 The 32-acre new site will accommodate a Terminus which will be able to handle 13,000 passengers an hour and 5,000 tons of goods a day. The passenger circulating area, waiting rooms, restaurants and railway offices will be built on a podium above the passenger

station; the podium will also accommodate a multi-storey car park and a bus terminus. An indoor stadium which can accommodate more than 15,000 spectators will also be built above the Terminus. An elevated road network will provide access to the entire complex.

3.26 The main line between Kowloon and Lo Wu is a single rail- way track. Planning is in hand for widening the track between Kowloon and Sha Tin to a double line except for the section through the Beacon Hill tunnel, remodelling the stations and constructing a spur line to the future race course at Sha Tin. Consideration is also being given to track-widening between Sha Tin and Tai Po Market.

Quarry Development

3.27 The Quarries Section appraises the construction industry's needs for quarry products and building sand and plans the availability of resources to meet these demands. It also plans to uprate the pro- duction of the Government quarries to meet the demands of the Civil Engineering and Highways Offices for aggregates and bitumen-coated materials by the introduction of modern quarrying methods and machinery. Attention is also directed to future testing requirements.

Electrical and Mechanical

3.28 Forward planning in the Electrical and Mechanical Office has three basic timescales each corresponding with the type of service concerned. A good deal of the Office's work is contingent on the long term plans of others so that much planning is concerned with the pro- vision of future services which are adequate, flexible and expeditious.

3.29 The shortest of these timescales is in connection with the com- pilation of schedules of preventive maintenance and planned overhauls of equipment. These must be kept under constant review in accord- ance with experience and the operational needs of client departments in order to optimise levels of equipment reliability and availability while preserving cost effectiveness. A considerable amount of work has been done and not only are improvements in each of these areas becoming apparent but greater results are expected in the future.

3.30 A high proportion of the construction work of this Office has to fit in with plans of others which are already well developed and this has a considerable effect on the type of forward planning which can be adopted. In such instances this means providing general in-

29

formation on the facilities which would be required for various kinds of plant and attempting to ensure that these facilities are incorporated into schemes from their inception. When this is done electrical and mechanical work can be incorporated in the usually limited time available.

3.31 Longer timescales are required in both the Operation and Maintenance Division and the Design and Projects Division for plan- ning in connection with the provision by the former of future services which will be adequate and timely, and the construction of major plants by the latter. The extensions to both Caroline Hill and Sung Wong Toi Workshops are in train together with further Vehicle Servicing Stations to provide the level of services required in the mid and late 70's. At the same time workshops management has been re-organized so that overhauls can be pre-planned, in such a way as to fit the needs of the equipment while facilities are kept in line with anticipated workloads.

3.32 A similar timescale is required in the consideration of future incinerator plants, electrical and mechanical services in future tunnels etc. In most of such schemes the provision of sites meeting environ- mental requirements has proved to be a major problem to be overcome and even when overcome has a great influence on the configuration finally adopted.

LAND

3.33 In carrying out the responsibilites of survey, mapping, town planning and the development and control of land, three factors are kept firmly to the fore:

(a) the need for continuous preparation and updating of survey maps and planning layouts which are basic to all forms of land development;

(b) the need for the establishment of a body a land administration principles in accordance with which land may be transferred to developers' hands, be they private or public, in an orderly and recognized manner so as to give effect to Government develop- ment policy;

(c) the need for flexibility of approach both to land use planning and the implementation of development policy so as to ensure quick and effective response to changes in economic climate and social needs.

30

3.34 The forward planning of the Survey Branch of the Crown Lands and Survey Office is directed to the preparation and updating of a variety of maps and plans sufficient to serve the needs of public and private developers and the community as a whole. In doing this, efforts are made to employ the most suitable modern techniques and equipment both for field survey and for reprographic processes in the Drawing Office.

3.35 The Planning Branch bases its work on the need to meet the demands of a population growing both in number and sophistication. It uses data provided by the Census and Statistics Department and other departments and from field research to assess the forward requirements of the community and translates these requirements into the provision, on outline development and layout plans, of land for communications and for industrial, residential and community develop- ment throughout the Colony.

3.36 The Land Branch is responsible for a large body of routine work concerned with land and property and its management and valuation; it gives effect to Government decisions by transferring Crown Land into the hands of developers both public and private. Its forward planning is based on known commitments for regrant and renewal of Crown leases and the potential property management com- mitment arising therefrom, on the expected demand for and availability of new Crown Land for disposal and on the need to give effect to certain new forms of development policy such as Urban Renewal, long term highways development and Mass Transit communications, provisions for containerization of cargo etc. in addition to the need for long term reclamation and land formation schemes, to anticipate long term demand for Crown Land for permanent development.

3.37 Within the Valuation Division, up-to-date and comprehensive analysis of all available land transaction data essential to the function of the Branch and its support of the Land Branch, Planning Branch, and other Government Department is proceeding, and an intensifica- tion and extension of work in this respect will be continued.

WATER

The Need

3.38 The demand for fresh water for domestic, industrial and com- mercial purposes has arisen from 25 million gallons per day in 1946 to 202 million gallons per day during 1972-73.

31

Digitized by

Google

3.39 A review of the probable future increase in demand was made in 1970, and it was estimated that the growth rate would be of the order of 8% per annum during the seventies. There are already indications that this growth rate will be exceeded, which demonstrates the need for a continuous planning review so that the necessary re- sources (such as storage reservoirs and desalting plants) can be developed and the associated treatment works, pumping stations, pipelines, service reservoirs and distribution systems can be built to satisfy the demand for water.

3.40 The variability in the rainfall into, and the volume of storage and size of catchment areas of the sixteen reservoirs, which at present provide Hong Kong's fresh water supply, imposes a need to plan the various draw-offs so that the productivity of the collective sources is maximized.

3.41 Planning for the development of the salt water flushing systems is similarly required. During the year, these systems supplied over 35 million gallons daily for sanitary purposes.

The Machinery

3.42 In the early post-war years, staff was scarce, and the need for work obvious. There was no specific planning section in the Water- works Office. Much of the thought on where new works were needed was done personally by the head of the office. As the organization grew, and planning became more complex, a single planning officer was appointed in 1965 and planning is now undertaken by a staff of four or five engineers responsible to a Chief Engineer. Outline proposals are prepared for new water supply schemes for proposed development throughout the Colony and also for revision of requirements in existing developments.

3.43 The planning for and development of operational programmes for existing resources is carried out by the Supply Division, and in- cludes the management, by computerization, of storage and supply.

The Method

3.44 The planning of resource development must begin with an estimate of the need-in this case, the future demand for water. Crudely, this can be done by extrapolation of the past trend. This method, however, ignores possible changes in the community which

32

Digitized by

Google

may make the future increase in demand quite different from that in the past. A more sophisticated complementary analysis can be made by subdivision of demand into categories-e.g. industrial, and various domestic categories-and with all available knowledge of future growth rates of each category of consumer, gleaned from population estimates, building programmes, etc., a picture of future demand can be built up from the estimates of its various parts. Estimates of this sort were prepared by the Water Resources Survey, and statistics to revise these are continuously being gathered by the Waterworks Supply Division.

3.45 When demand is estimated, the possible resources can be matched to it, taking account of practical time-tables for investigation, design and construction of large civil engineering works. This work showed the need to proceed with works to increase the capacity of the Plover Cove system, and to begin investigations for the new reservoir at High Island. It was also shown that desalting would be needed in Hong Kong. As a result an experimental desalting plant was installed to assess the performance in Hong Kong of materials used in evapora- tion for the manufacture of fresh water, and to establish a suitable location for the larger permanent plant currently under construction.

3.46 Planning of the supply facilities necessary to deliver water to the consumers involves assessment of the best physical subdivision into supply zones, limited in extent and level, calculation of probable demand in these zones, based on estimates of use, population, and unit demand rates and selection of suitable sites for pumping stations, pipe- lines and service reservoirs. The process is the same in established but growing areas, with the added guidance of a record of demand growth. All of this planning is duplicated for salt water flushing supplies.

3.47 Reservoir operational planning has historically depended on frequent adjustments of the supply zones of the various reservoirs so that the rate of draw-off is changed. The object is to avoid overflow from some reservoirs whilst others are not yet full, or conversely, to avoid some reservoirs emptying before others. The 'normal' com- plications of this work are the physical limitations on rate of draw- off from any particular source, the estimation of demand in the supply zone selected, and the rapid changes which can take place in the relative storage positions of the reservoirs due to mal-distribution of rainfall.

33

The Time Scale

3.48 The horizon for the different planning purposes varies. Thus, from conception to completion, a large reservoir may need 8-10 years, a treatment plant 5-6 years, service reservoirs and pumping stations 3-4 years and trunk mains 1-2 years. The arrangements for draw-off from reservoirs to maintain a proper distribution of resources must be planned months ahead, but sudden storms may require alterations to be made overnight.

3.49 All of this planning requires experienced professional staff trained in many inter-related disciplines, and maintaining such an organization might be said to be the most important planning function of the management of the Waterworks.

GENERAL

The Architectural Office is responsible for the control of the greater part of the Government building programme. Whilst most of the work is designed and supervised by the staff of the office it is some- times necessary to engage private architects, engineers and quantity surveyors to assist with the programme of work.

4.02 The maintenance of buildings owned by, or leased to, Govern- ment, including the routine management of Government-owned prop- erty, is the responsibility of the Maintenance Branch of the office.

4.03 Since July 1967 this office has assumed responsibility for the construction and maintenance of the majority of buildings required for the use of the British Armed Forces and their dependants within the Colony.

4.04 The Architectural Office staff, which in the year under review numbered 1,441 including 367 minor staff, supplies a fully comprehen- sive range of skills required for the design and construction of buildings of all types and includes architects, structural engineers, quantity surveyors, building services engineers and maintenance surveyors, together with subordinate technical staff and outdoor supervisory staff. In addition, the office has its own clerical and accounting sections.

4.05 All work was carried out on contract, and expenditure on new works, excluding furniture and equipment, amounted to $198,249,000. Of this sum, $68,565,000 was spent on Resettlement and Low Cost Housing, $120,421,000 on other Government projects under- taken in this office and $9,263,000 on Government projects undertaken by private architects. The value of work ordered on the Maintenance Contracts amounted to $57,225,000; $4,145,000 was spent on electri- city and the cleaning of Government buildings under the control of this office.

4.06 The Quantity Surveying and Building Services Branches advise the Director of Education on drawings, specifications, contract docu- ments, tenders, final accounts, building services installations and maintenance work for grant-in-aid and subsidized schools, and site inspections are made. Work estimated at $55,300,000 was started on 50 new projects and work costing $19,000,000 was completed on 43 schools. Repair and maintenance work estimated at $3,400,000 was started on some 185 schools and was completed at a cost of $3,000,000 on 181 schools. Advice was given on interest-free loans. amounting to some $12,500,000, to 7 schools.

4.08 All four Architectural Divisions are engaged on new works and each is headed by Chief Architect. Divisions I and II are each sub-divided into three groups headed by a Senior Architect, each group forming a working team capable of handling the whole process of designing the buildings and preparing the architectural drawings for the projects allocated to them. To each of these groups is allocated the building programme of specific Government departments, whilst other buildings designated 'general' are distributed amongst the groups. - This system simplifies liaison with the departments concerned and enables each group to acquire a background of experience of the * building requirements of their client departments. Division III is responsible for the Resettlement and Government Low Cost Housing programme in addition to a number of other projects such as crema- toria, columbaria, standard clinics and recreation grounds. Also in Division III is a minor works group, headed by a Senior Architect, which deals with the very large number of minor projects in the pro- gramme. Division IV is responsible for military and defence works projects.

4.10 This Branch is under the control of the Government Quantity Surveyor, assisted by the Chief Quantity Surveyor and is divided into six sections each under the supervision of a Senior Quantity Surveyor, dealing respectively with the following matters:

(a) Projects generally exceeding $500,000 for which bills of

quantities are prepared;

(b) Special projects such as Kai Tak Airport development and

large hospitals;

39

(c) Resettlement and Low Cost Housing;

(d) Maintenance contracts and advice on subsidized schools; (e) Defence works requiring Bills of Quantities and projects not exceeding $500,000 for which specifications but no bills of quantities are prepared;

(f) Estimates, materials supplied through Government Supplies

Department and cost statistics.

4.11 The Branch is responsible for the preparation of estimates, bills of quantities, contract documents, valuations for interim pay- ments, final accounts and contractual claims for all Architectural Office projects. It is also responsible for arranging contracts and checking accounts for the maintenance of Government buildings and British Armed Forces buildings, including checking the measurement of all works orders exceeding $1,600 in value.

4.12 The Branch is staffed by 45 Quantity Surveyors and profes sional assistants; supporting technical staff is engaged on preparation of contract documents for minor works, 'working-up', site measure- ment, checking accounts and similar duties.

4.13 The number of professional staff on the present establishment is insufficient to deal with the current building programme but further posts have not been recommended due to the extreme difficulty in recruiting staff to fill existing vacancies and it has therefore been necessary to employ the services of five private firms of quantity surveyors for some 25% of the output of the Branch for the year under review. The situation is further aggravated by the increasing number and complexity of claims submitted by contractors.

4.14 During the year under review 224 contracts were placed to a total value of $202 million and some 8,925 accounts were checked for work executed under the Maintenance Contracts to a total value of $45.52 million.

4.15 Building costs continued to rise throughout the year and the total increase was about 12% over the previous year. Although this is slightly less than the rate of increase reported for the previous year more than half of the increase occurred in the last few months of the year under review, due to the sharp rise in the cost of mild steel rein- forcement and plywood since November 1972. The deceleration of the rate of increase may be attributed to an apparent slackening in

4.20 This Branch is under the overall control of the Government Building Services Engineer and is organized into two main divisions, New Works and Maintenance. The New Works Division, headed by the Chief Building Services Engineer, is sub-divided into five Sections each under the supervision of a Senior Building Services Engineer with its complement of Building Services Engineers, Assistant Building Services Engineers, Engineering Assistants and supervisory staff. Four Sections each support an Architectural Division and one supports an Engineering Division of Civil Engineering Office, each being responsible for the design, specification and supervision of electrical, lift, air- conditioning, refrigeration, mechanical services and liquefied petroleum and town gas services installations in new public works projects (including Resettlement and Government Low Cost Housing and Hung Hom Development) and military new works projects. The Maintenance Division, headed by a Senior Building Services Engineer, has a similar complement of staff and is responsible for both the maintenance of electrical, lift, floodlighting, gas and fire alarm installations and the provision of air-conditioning in existing Government and H.B.M. Services Establishments.

4.21 In addition to projects designed in the Architectural Office, the Branch is responsible for the design, specification and the supervi sion of building services installations in buildings designed by private architects on behalf of Government. The Branch has also commis- sioned Consultant Engineers for building engineering services estimated at $54.82M in twelve major projects at present under investigation, being designed or in progress. Assistance has also been given to the Education Department on the subject of building services installations in grant-in-aid and subsidized schools and to the Commissioner for Resettlement and the Commissioner for Housing on building services engineering in flats, estates and factories under their respective control.

4.22 During the year, contracts or sub-contracts were let for build- ing services on New Works to a total value of $26.429M and work to the value of $10.916M was ordered on the electrical, lift, and other maintenance contracts. In addition, standard fittings and other materials to the value of $11.905M were ordered through the Govern- ment Supplies Department for incorporation in the works.

4.23 The Branch continued the task of rewiring Mark I and Mark II Resettlement Estate blocks in the final year of the four year pro-

K. R. R. BOYCE, F.R.I.C.S. P. J. CORSER, A.R.I.C.S. (Acting)

Chief Maintenance Surveyor:

P. J. CORSER, A.R.I.C.S.

J. K. PENNEY, A.R.I.C.S. (Acting)

4.24 This Branch, under the overall control of the Government Maintenance Surveyor, is responsible for the Maintenance of and minor alterations or improvements to all Government buildings (except those under the control of the Housing Department) and Services establish- ments.

4.25 The work on Government buildings is divided into three contract areas, Hong Kong Island, sub-divided into six districts, Kowloon, sub-divided into four districts, and New Territories and Islands, sub-divided into four districts. Approval has been given to re-divide both Hong Kong and Kowloon into eight districts but lack of staff has precluded this from being put into operation. Three maintenance surveyors, under the supervision of a Senior Maintenance Surveyor, are in charge of the work in the first section and four main- tenance surveyors, under the supervision of a Senior Maintenance Surveyor, are in charge of the work in the second and third sections. A Clerk of Works assisted by assistant clerks of works, and/or building foremen, is responsible for the day-to-day supervision of work in each maintenance district. Work is mainly executed by a term contract based on a Schedule of rates but small groups of directly employed labour have been established this year in major building complexes to execute day to day and emergency repairs. This use of directly employed labour will be expanded further in due course and when adequate technical staff can be recruited. Maintenance of electrical and other services, under building services engineers, assisted by inspectors, assistant inspectors and foremen, is also organized on a regional basis. Checking of accounts is carried out by sections of the Quantity Surveying Branch and Building Services Branch.

4.26 The maintenance and minor improvements of Services estab- lishments is co-ordinated by a Senior Maintenance Surveyor and is

divided into three areas, Hong Kong Island, Kowloon and New Terri- tories and administered by three maintenance surveyors assisted by depot technical officers each working from a depot situated in his area, with a supporting supervisory staff of clerks of works and fore- men, together with clerical staff. Approval has been given for the creation of a fourth depot which will deal solely with R.N. and R.A.F. establishments but again lack of staff has precluded this from being put into operation. Direct labour is employed in the execution of some of the work on Services establishments. The Branch is also responsible for roads, water supplies, sewage disposal and playing fields. within military areas.

4.27 Scheduled maintenance programmes were carried out on Gov- ernment buildings and leased buildings, and day-to-day maintenance of buildings and redecoration of quarters was carried out as necessary. Total expenditure on this work amounted to $25,350,000.00. Similar work was carried out on Services establishments and the portion carried out by contract amounted to $18,250,000.00.

4.28 A total of 202 major and 1,400 minor items of alterations, additions or improvements to Government buildings were executed at a cost of $2,500,000.00. Work of a similar nature carried out in Services establishments amounted to $4,325,000.00.

4.29 Works were executed by three triennial building maintenance contracts, twenty-three annual/triennial specialist contracts and several triennial cleaning contracts.

4.30 Other items of work undertaken by the Maintenance Branch included minor security and defence works and items for other depart- ments ordered on the maintenance Contracts and amounted in all to some $5,000,000.00. Surveys and reports were made on several prop- erties acquired by Government on lease. Regular inspections were made, by the building supervisor and his staff, of those offices and non- departmental quarters for whose cleaning and general management the Maintenance Branch is responsible.

GENERAL

5.01 The Buildings Ordinance Office is responsible, on behalf of the Building Authority, who is the Director of Public Works, for the control of all private building and street works, and for action in respect of dangerous or potentially dangerous buildings, defective private drainage, and unauthorized alterations and changes of use in existing buildings. The Office is also responsible for the administration of the Demolished Buildings (Redevelopment of Sites) Ordinance.

5.02 The control of building development on private land is under- taken by five general divisions covering Hong Kong island, the Kowloon peninsula and the New Territories. There are two other divisions,the Dangerous Buildings Division and Works Division, which are specialist divisions dealing with works primarily associated with dangerous or potentially dangerous buildings in the Colony, and any building work carried out by the Government Contractor in default of the owner. A chart indicating the organization and functions of the Office is shown on page 53.

5.03 The Office was represented by senior staff on the following committees or boards:

5.04 The Public Works Department/Authorized Architects Liaison Group, consisting of representatives of the Office and members of the Hong Kong Institute of Architects and the Engineering Society of Hong Kong, serves as a useful link between Government and architects and engineers in private practice. Two meetings were convened during the year, in which views were exchanged on matters arising from the interpretation and application of the Buildings Ordinance.

5.05 The office maintained, as in past years, two separate organiza- tions rendering service to the public in the event of emergencies. Both work in conjunction with the Police. The first organization provides professional and technical staff on a round-the-clock basis to assist in matters arising from building collapses, fires, landslides, etc. The second organization is set up, during typhoons or when there are excessive rains, by the assembling of two groups of professional officers, one on each side of the harbour, on a shift basis, to attend to reports of damage or danger to private buildings.

5.06 The unprecedented rainstorms in June, which lasted for several days, brought about a large number of landslides causing many deaths and destruction of property worth millions of dollars. Of these landslides, the most significant occurred around the areas of Po Shan Road, Conduit Road, Kotewall Road, Shiu Fai Terrace and Sau Mau Ping Resite Area. During this period, over 250 cases of damage or threatened danger to private buildings were reported, and the Office was forced to suspend all normal work in order to deal with these emergency matters. At the end of June, Commission of Enquiry was appointed by the Governor to inquire into the circum- stances in which these disasters occurred and to make recommenda- tions to prevent the recurrence of such disasters.

5.07 During the period under review, disciplinary proceedings were instituted by the Building Authority against one authorized architect and four registered contractors for failing to comply with

55

the Buildings Ordinance during construction of buildings. The architect and two contractors were reprimanded; the other two contractors were permanently removed from the register of building contractors.

5.08 The Working Party on Structural Regulations was re-convened at the end of the year for the purpose of converting the proposed draft structural regulations into metric form.

5.09 The Chief Structural Engineer, Mr. H. K. CHENG, later promoted to Government Structural Engineer, represented the Depart- ment at the International Conference on the Planning and Design of Tall Buildings held in August at Lehigh University, Bethlehem, Pennsylvania, U.S.A. He also served as a State-of-Art reporter of Technical Committee 20 on Concrete Design Standards and presented at the Conference his paper on Concrete Design Standards in Asia.

5.10 The Head Office is responsible for matters of policy, law revision, co-ordination, disposition and training of staff. The Principal Government Building Surveyor, in overall control, is assisted by the Government Building Surveyor (General) and, with effect from September, the occupants of the newly created posts of the Govern- ment Building Surveyor (Works) and the Government Structural Engineer.

5.11 With an increased establishment of building surveying and structural engineering staff, the Office was re-organized in November. The original three general divisions were expanded to five. In addition to the Dangerous Buildings Division, a new Works Division was created to form the Specialist Branch.

5.12 In recognition of the need for greater control over soil en- gineering aspects in connection with foundation and site formation works, five civil engineers were seconded to the office in September to form a new Civil Engineering Unit.

5.13 The large volume of emergency work generated by the June rainstorms paralysed the normal function of the General Divisions. Processing of plans was suspended for about a month as the staff of the General Divisions were directed to assist in dealing with dangerous buildings and sites. A substantial backlog of applications for approval of plans was created, which continued to increase throughout the year.

To cope with this unusual situation, the Building (Amendment) Ordinance 1972 was introduced, which was later supplemented by the Buildings Ordinance (Extension of Operation of Section 30A) (Amendment) Regulations 1972, to relieve the Building Authority of the obligation to deal with applications for approval of plans, consent to commence building works and for occupation permits within the respective statutory periods under the Buildings Ordinance. On 1st December, the period of 14 days was reintroduced for the processing of applications for occupation permits.

5.14 The principal functions of the general divisions are to scru- tinize and approve all plans for private building and street works, to grant consent to commence work, to carry out periodic inspections during construction, and to inspect and issue occupation permits on completion.

5.15 A total of 720 occupation permits were issued during the year, showing an increase of about 5% over the previous year. The declared capital cost of these completed buildings was $1,272M, an increase of about 28% compared with the figure of $991.2M for the previous year. This figure, the highest ever recorded since the building boom of the mid-sixties, when it reached its peak in 1966 with a record value

of $1.058M, reflects the high activity in the private sector of the build- ing industry. There is also indication that the building boom is likely to continue, for in the last quarter of the year under review 371 new building proposals were submitted, the highest number recorded in recent years.

5.16 Due to the favourable state of stability and prosperity existing in the Colony, private developers continued to show great confidence in the real estate field. It was noted that fewer proposals for industrial buildings were submitted this year, but instead there was a marked increase in the submissions for large office and hotel schemes. A new trend was also observed in the demolition of existing cinema buildings and their replacement by office buildings comprising office accommoda- tion on upper floors and commercial space and parking facilities on lower levels.

5.17 As a result of shortage of building land and great demand for small residential units, a tendency has developed to demolish the low density tenements, built in the early post war period, to make way for the high density blocks of small flats. It was also noted that car parking spaces were provided in many proposals for domestic accommodation, although they were not required under the lease conditions or by any other authority.

5.18 Several interesting private development projects were com- pleted or near completion during the year. These include the Connaught Centre, a 52-storey office building which has received a temporary occupation permit for the first sixteen storeys, the 34-storey Excelsior Hotel near the Island Entrance to the Cross Harbour Tunnel in Causeway Bay and the 35-storey Furama Hotel in Connaught Road, Central. Other noteworthy projects submitted for approval during this period include the World Centre, a 41-storey building with convention halls and offices, the 20-storey Hong Kong Art Centre containing theatres, studios, offices and other accommodation connected with the arts, a complex of multi-storey residential blocks with shopping facilities, restaurants and swimming pool all within one site on Lion Rock Road and the development of Stage 8 of Mei Foo Sun Chuen, comprising an automobile service station, shops, pedestrian con- course, parking, kindergarten and domestic tower blocks.

5.19 The backlog of structural plans awaiting processing increased rapidly after the June rainstorms. This was mainly due to the structural

engineering staff being engaged full time on emergency duties in con- nection with the rescue and investigation work in all the affected areas. They were at that time particularly involved with the investigation into the structural aspect of the collapse of Kotewall Court at Kotewall Road as a result of the landslide, and in the surveillance of the Peak area where some slope movement was observed.

5.20 Measures to clear the backlog were taken towards the end of the year. Messrs. Harris and Sutherland, consulting Civil and Structural Engineers, of London, were engaged by the Government to assist in checking structural plans submitted for approval by authorized architects. Progress of the work has since been well maintained.

5.21 The establishment of the Civil Engineering Unit enables the office to give a more thorough and detailed check on proposed and existing site formation and foundation works. During this period, the Unit dealt with 396 cases, a monthly average of 66. In addition the Unit has dealt with a number of cases requiring substantial repair of damage sustained during the June rainstorms. The Unit is also currently involved, in conjunction with consultants, in the preparation of a guide for authorized architects to ensure every precaution is taken to avoid future landslips etc. and to provide a sensible basis for the full and safe utilization of building land.

5.22 Due to the high pressure on the staff of the Office resulting from the effect of the June rainstorms, general increased activity in the building industry and shortage of staff at professional levels, little progress has been made in dealing with unauthorized building works. during the year. However, in January, following a survey of 952 units of a large residential block in King's Road, 357 notices under the Buildings Ordinance were served on the respective owners, requiring them to remove all the unauthorized works and to restore the building to the condition in which it had been certified for occupation.

5.24 The advent of the rainstorms of mid-June escalated dangerous building work with emergencies demanding the total activities of the Division augmented by staff from other Divisions. This continued at high pressure for several weeks and at a lower level throughout the year. There were many emergency demolitions and the clearance and recovery work at Kotewall Court alone occupied the staff of the Division, assisted by officers from other Divisions, working round the clock on a shift basis for 10 weeks.

5.25 In the latter part of the year it was possible to re-commence survey of potentially dangerous buildings on a planned survey basis, and many buildings have been closed and demolished or repaired as a result, while the routine re-inspection of suspect buildings has con- tinued and many were found to have deteriorated to a point where closure and demolition is necessary.

5.26 The Division is also responsible for action under the Demo- lished Buildings (Redevelopment of Sites) Ordinance by the service of Redevelopment Notices which enable displaced tenants to claim compensation and re-housing, while the service of Redevelopment Orders where appropriate requires the redevelopment of the property within a specified period.

5.27 Action in connection with the repair of defective drainage continued at a high level with the size and scope of the work increasing in large building complexes in multiple ownership.

5.28

The Division inspected and reported on buildings which may be affected by Mass Transit proposals.

Chief Building Surveyor:

G. F. HOGG, F.R.I.C.S., C.Eng., M.I.Struct.E.

5.29 This new Division was formed to take over all works functions of the Buildings Ordinance Office arising from the necessity to carry out works ordered under the Buildings Ordinance in default of owners, mainly in connection with the demolition or repair of dangerous build- ings and signs, control and enforcement cases, defective drainage, and danger arising from site formation or landslips associated with buildings.

5.30 At the same time a Senior Building Surveyor was seconded from the Buildings Ordinance Office to Crown Lands and Survey Office to assist with preparation and administration of a new contract for the clearance and preparation of Crown Land under the Crown Land Ordinance 1972. This officer is associated with the Works Division and took over the work and staff previously within the Dangerous Buildings Division dealing with maintenance of buildings under the control of the Property Management Division of Crown Lands and Survey Office and done under the Buildings Ordinance. Office Works Contract.

5.31 The Works Division also became responsible for demolition, under contract, of buildings acquired for urban renewal within the Pilot Scheme, including the shoring and maintenance of stability of adjoining buildings.

5.32 The Division was also called upon to furnish estimates for demolition of buildings and removal of balconies in connection with proposed elevated roadways.

5.33 At the time the Division was formed 65 Work Orders under the Buildings Ordinance Office contract were in hand and a further total of 107 were issued up to 31st March, 1973. The total expenditure under this contract during the year was in the region of $1,150,000.

Staff

STAFF, TRAINING AND WELFARE

5.34 The Office continued to be below strength, particularly at the Building Surveyor and the Structural Engineer levels. Every effort was made to recruit professional Building Surveying and Structural En- gineering staff both locally and abroad.

Training

5.35 The Technical Training Board continued to guide and train the Surveying Assistants (Building) Class III. A programme of lectures and site visits was again instituted to prepare the trainees for the upgrading examination conducted by the Board. Of the twelve candi- dates in the Examination, five were successful and recommended for promotion to Class II on completion of their normal four-year trial period.

GENERAL

6.01 The Civil Engineering Office is responsible for harbour en- gineering works, reclamation, and land development and for the overall planning, design and construction of new stormwater drains, sewers, sewage treatment and disposal systems and controlled tipping of municipal refuse. It also undertakes civil engineering works required for the development of Kai Tak Airport and the Kowloon-Canton Railway. In addition, it operates all P.W.D. material-testing labora- tories and Government quarries, administers the Sand Monopoly and all contracts for quarrying let out to private concerns and provides liaison to facilitate the development and maintenance of Kai Tak Airport.

6.02 The Office is divided into 5 divisions, 2 sections and 1 unit, the responsibilities of which are outlined on the organization chart on page 63. Consulting engineers are employed to carry out certain projects primarily due to staff shortage, although in a few instances their expertise is needed.

6.03 All new projects and most maintenance works are carried out by contract, but the Office maintains a direct-labour force for the operation of Government quarries, sewage-treatment works and float- ing plant. Satisfactory progress was generally maintained throughout the year, for which the non-recurrent expenditure was $134.12M. Another $26.42M was spent on maintenance and minor improvement works.

6.04 Projects completed or under construction and particulars of site formation schemes are listed in Appendices O, P and Q respec- tively. A list of projects undertaken by consulting engineers is given at Appendix R, while statistics relating to road and drainage works,

6.06 Where the formation and servicing of undeveloped areas in Kowloon and the New Territories for urban use involve major en- gineering works, the Development and Airport Division is responsible firstly for investigating the engineering feasibility of such development and secondly, in those schemes which are approved, for the formation of the land and the provision of services.

6.07 The Division is also responsible for civil engineering works at the Airport and for the planning of future controlled tips for the disposal of refuse in Kowloon and the New Territories. The Railway Section was expanded to an independent Division during the year and was detached from this Division.

Planning and Investigation

6.08 The feasibility reports on Development at Kowloon Bay and Tsuen Wan/Kwai Chung North were completed and a report on Development at Tsing Yi was nearing completion. Other feasibility studies in hand were on areas north of Tat Chee Avenue and La Salle Road and also at Tai Hom.

6.09 The Division's annual contract under which site investigations were carried out for all offices of the Department functioned well. The total depth of probes, drill holes, bore holes and open trial pits sunk was 59,107 feet.

Projects under Construction

6.10 Statistical details of land-formation projects under construc- tion are given at Appendix Q and of other projects at Appendices O and P.

6.11 A description of the works carried out is given below under the appropriate district headings.

Kowloon

6.12 At Ho Man Tin Development Area, a contract for the removal of stockpiled materials from Fat Kwong Street landslide was

completed, while the site formation contract at Stage VII continued to progress satisfactorily with some 9 acres of land being formed for residential, commercial and education uses. A road surfacing contract for Stages VIII and X was started. At Lung Cheung Road Develop- ment Area 1, a road surfacing contract for part of Cornwall Street Extension started and is progressing well.

6.13 Reclamation continued at Kowloon Bay where about 702,000 cubic yards of materials from Government projects and private build- ing sites was deposited to form some 37 acres of land.

Kwai Chung Tsuen Wan New Town

6.14 The contract at Kwai Chung Area 29B, to provide 20 acres of land for industrial, storage and Government uses, was completed.

6.15 Reclamation continued at Gin Drinkers Bay where some 244,000 cubic yards of material from Government and private works was deposited, bringing the total area reclaimed to 296 acres.

Sha Tin New Town

6.16 The Stage I Phase I development scheme was originally designed to provide some 100 acres of land to accommodate a popula- tion of 30,000 people. Extension of its scope to include an additional Government Housing Estate site in order to keep pace with the accelerated housing programme arising from the approval of the '10 Year Housing Target' was being contemplated, as well as the inclusion of certain roadworks required to handle the expected increase in traffic due to the proposed New Race Course.

6.17 Contracts in Areas 7, 8 and 16 to provide sites for a Govern- ment Housing Estate and for residential/commercial and industrial building made good progress; some 625,000 cubic yards of materials. was dumped, bringing a total of 61 acres of land formed in those areas. An underbridge was substantially completed to provide access through the railway embankment to the future industrial sites in Area 16.

6.18 Planning of the next phase of Sha Tin Development was in hand.

Tuen Mun New Town

6.19 The name of the New Town was changed from Castle Peak to Tuen Mun, the traditional Chinese name for the area.

6.20 Stage IA of the New Town Development entered its final phase. It provides formed land, roads and services for private residen- tial purposes, Government housing, industrial sites, Government, in- stitutional and community use, as well as open space for recreation; it will be able to accommodate 57,500 persons.

6.21 A further site formation contract was completed during the year, contributing another 8 acres to the area of formed land. Some of the roads and drains in Areas 9 and 12 were completed. A sewage pumping station and sub-marine outfall at Pak Kok Tsui were com missioned and the associated staff quarters were completed and occupied.

6.22 A contract was started for the construction of approximately one mile of main road through the northern half of the New Town. Under the same contract, some 6 acres of site formation were substan- tially complete and construction of roads and drainage in Areas 10B and 12 was also in hand.

6.23 Planning of Stage IB of Tuen Mun Development was nearing completion.

Airport Development

6.24 Stage I of the Apron and Taxiway Extension Project was com- pleted by the conversion of the old outer taxiway into six aircraft parking bays. Stage II of the same Project was commenced with a con- tract to provide a further six aircraft parking bays together with related taxiways.

6.25 Construction of the Link Taxiway to provide rapid access to the parking apron via a high speed turn-off from the runway continued and the associated drainage works were nearing completion.

6.26 Vehicular access in the cargo area was much improved with the completion of a new road and bridge across the Kai Tak Nullah, and construction of a new access road at the eastern end of the Airport was nearing completion.

6.27 3,700 feet of six-way cable ducts to cater for various electrical systems were installed around the north-west end of the runway. Civil engineering works for a temporary car park providing 271 spaces for staff of airline industries were completed.

69

6.28 A contract was started for the civil engineering works con- nected with the Apron Services Complex, which includes decking 300 feet of the Kai Tak Nullah and the reconstruction of the northern access road bridge.

6.29 Planning was in hand for Kowloon Bay Development drainage works, affecting the airport expansion. Tenders were invited for a 1,500 ft. extension of the Kai Tak Nullah and construction of a vehicular access bridge. Planning for the reconstruction of the R.A.F. taxiway was also in hand.

6.30 Maintenance and minor new works costing almost $500,000 were carried out during the year and together with supervision of private projects, notably the oil companies' new fuel mains thrust- bored under the runway, occupied a considerable amount of staff time, including night works during the runway-closure period.

General

PORT WORKS DIVISION

Chief Engineer:

H. R. A. CHAMBERLAIN, B.Sc., C.Eng., F.I.C.E.

6.31 The Division is mainly responsible for the construction and maintenance of seawalls, breakwaters and reclamations throughout the Colony and for the investigation of development schemes on Hong Kong Island. Good progress was maintained throughout the year on most major projects. Minor works completed during the year included a number of light beacons and navigational aids and maintenance dredging at various locations throughout the Colony waters. Other activities carried out by this Division included marine site investiga- tions, hydrographic surveys and an investigation into the problems of refuse disposal by controlled tipping on Hong Kong Island.

Hong Kong

6.32 At Aldrich Bay, work commenced on 300 feet of submerged rubble mound and reclamation which, on completion, will provide land for five boatyard lots. Work on 1,730 feet of seawall required to provide land for resettlement and industry at Chai Wan proceeded satisfactorily. Another section of 1,700 feet of seawall was being designed with a view to commencing construction in mid-1973.

6.33 Reclamation and seawall construction commenced near the Macau Ferry Terminal as part of the Central Stage V Reclamation Scheme. Sufficient seawall was constructed to allow reclamation to start. The planning for Aberdeen Reclamation Stage II Scheme, which includes a number of separate reclamations within the Aberdeen and Ap Lei Chau area, was finalized and a works programme was prepared.

6.34 A feasibility study for a large reclamation along the water- front of the Western District of Hong Kong Island was completed. Investigation for Tai Hang Road Development continued.

Kowloon

6.35 In the Yau Ma Tei typhoon shelter the remaining sections of seawall between Man Cheong Street and Shan Tung Street were com- pleted and the area behind the wall reclaimed for the extension of Tong Mi Road. A small launch landing to serve the Government Dockyard was built and the reconstruction of a jetty at Stonecutters Island was completed.

6.36 The construction of breakwaters for the Kowloon Bay Typhoon Shelter in the vicinity of the Kai Tak Runway Extension was well advanced.

6.37 Planning and design of the first stage of the Sham Shui Po Reclamation Scheme, which includes 25 acres of reclamation and a ferry pier, was nearly complete. The pier will replace the existing one which cannot cope adequately with the present traffic.

New Territories

6.38 A jetty at Sai Wan, Cheung Chau, was completed, as were a new pier at Sha Lo Wan and a sea-defence wall at Tai O, both on Lantau Island. Design work for a new ferry pier at Mui Wo was in hand.

6.39 Six further beacons have been constructed in Deep Bay to mark the navigable channels leading to Sham Chun River and Yuen Long Creek. The work on converting Yin Pai Beacon, Tolo Harbour, to a lit beacon was completed, together with landing facilities for maintenance purposes.

6.40 Other works completed included the provision of covers for the public piers at Yung Shue Wan and Tsing Yi to provide shelter for people using these piers.

Kwai Chung Container Terminal

6.41 The Division checked and approved the design and working drawings of the developers under the Buildings Ordinance and Sale Conditions. The three berths under construction were put into opera- tion in the latter part of the year.

6.42 The dredging of the sea approaches to the terminal was nearing completion. Sufficient dredging had been carried out to allow the first container ship to come into the terminal in September 1972. Mean- while, Stage I of the access road system to serve the terminal was completed by this Division in time for the operation of the first berth.

Maintenance and Dredging

6.43 General maintenance and repairs were carried out to Govern- ment piers, seawalls, breakwaters, navigational markers and light beacons.

6.44 The Division's two pontoon dredgers continued maintenance dredging at sewer and nullah outfalls, pier approaches and saltwater- pumphouse intakes. The quantity of spoil removed by these dredgers amounted to 33,827 cubic yards. The self-propelled hopper dredger continued dredging work, mainly in the Central Fairway, and removed a total of 220,000 cubic yards of spoil.

6.45 The Division's divers carried out underwater inspections of seawalls, piers, pumphouses, submarine outfalls and water mains. A total diving time of 416 hours was recorded.

Boring and Surveys

6.46 336 marine boreholes totalling 11,441 feet were sunk at various places in the Colony waters using the Division's boring barges.

6.47 The Survey Section had a very active year both for marine and land survey. Current observations were made at Kwai Chung and Chai Wan.

General

6.48 The Division is responsible for the investigation, planning. design and construction of all new stormwater drains, sewers and sewage disposal systems in Hong Kong, Kowloon and the New Terri- tories. The Division is also responsible for operation and maintenance of sewage plants.

Construction

6.49 Major works carried out during the year included the con- struction of main stormwater drains and sewers in Shan Kwong Road as well as a nullah at Staunton Creek, Hong Kong, the construction of a temporary screening plant at Lai Chi Kok, drainage improvement for Wong Tai Sin Resettlement Estate, Kowloon and the implementa- tion of the last two stages of the Shing Mun River Flood Control Scheme in the New Territories.

Planning and Design

6.50 New designs included the extension of sewer and stormwater culverts in Chai Wan, stormwater diversion for the Kennedy Town Telephone Exchange, drainage remedial works in Shau Kei Wan, Hong Kong, sewage-screening plant in Sham Shui Po, Kowloon, Yuen Long sewage-screening plant and a temporary sewage-treatment plant for Sha Tin New Town, New Territories. Planning was carried out for proposed submarine outfalls in Chai Wan and Aberdeen and for a proposed sewage-screening plant in Kwun Tong. To cope with new developments, drainage layout plans were prepared for Cheung Sha Wan Reclamation Area, Lei Yue Mun Village and Cha Kwo Ling.

Studies and Investigation

6.51 Theoretical and field investigations continued for the assess- ment of spare capacity of sewer systems in Hong Kong, Kowloon and major centres of the New Territories.

6.52 The final reports submitted by the Consulting Engineers, Messrs. J. D. & D. M. Watson, on the Hydrological Surveys of Victoria and Tolo Harbours were accepted and published.

6.53 Bottom drifters were released in May and November 1972 at various locations in the Colony waters to study the movement of bottom sediments in connection with the Hydrological Surveys.

6.59 With the continuing expansion of the civil engineering pro- gramme without a corresponding increase in professional and technical staff and due to the specialised nature of some of the work and in- vestigations, it has been necessary to engage consulting engineers to assist in implementing the programme and their involvement is likely to increase in the foreseeable future.

6.60 All projects under consulting engineers previously dealt with by other Divisions were taken over by this new Division during the year and six further projects were commenced. Eight firms of con- sulting engineers were engaged on 17 projects and another 4 projects intended to be undertaken by consultants were being initiated. Eight of the projects were investigations or feasibility studies and reports on three of these were received.

6.61 Construction work commencing during the year included Stage I of Clear Water Bay Road Development and, at Kai Tak Airport, the road tunnel, the overlaying of the existing runway, runway extension paving and electrical works.

Government Quarries

6.64 The Government quarries at Diamond Hill in Kowloon and Mount Butler on Hong Kong Island are operated by directly-employed labour to produce bitumen-coated stone for the Civil Engineering and Highways Offices and aggregates for P.W.D. and for sale. Diamond Hill Quarry has a plant producing ready-mixed concrete which is mostly used for lean concrete for road works. In response to increased demand, production of crushed stone increased by one-third over 1971-72. Production of bitumen-coated materials remained at last year's high level but by the end of the year demand was exceeding production capacity.

6.65 Modern high-capacity crushing plant to replace some of the old crushers and augment the rest of the plant was purchased for Mount Butler Quarry and plans were made to install it. Plans were finalized for similar new crushing plant at Diamond Hill Quarry and were in hand for new asphalt-mixing plant to replace old plant and increase production capacity of bitumen-coated materials there.

Private Quarries

6.66 The six private quarries operated on Government contracts increased production. In accordance with plans to replace small quarries, held on short-term permits, with quarries held on long-term Government contracts and operated on a large scale, tenders were called and a contract signed for the right to quarry stone at Cha Kwo Ling combined area for a ten-year period. The area is at present operated as two contract quarries and the new contract will take over and operate one large-scale quarry in the area as from mid-1974 when the present quarries' contract periods expire.

6.67 Of the six quarries still operating on short-term Crown Land Permits at the end of 1971-72, two were closed, three were reduced to continuing on a month-to-month basis and new permit conditions, limiting quarrying operations, were included for the sixth.

6.68 Production continued to be supplemented by ancillary crush- ing plants processing the stone extracted in levelling development sites.

Sand Monopoly

6.69 Building sand is sold to the public through the Sand Mono- poly at a standard price, which remained at $16.50 per cubic yard

throughout the year. Sand is dredged from the seabed by a contractor operating under a Government contract and delivered to depots for subsequent sale by Government to the public. Sand for building pur- poses is only in exceptional cases taken from waters adjacent to the coastline of Hong Kong and then only from carefully selected sites; the reason for this is to preserve the amenities of the Colony's coastline. To supply the large quantities of sand to meet Colony-wide demand, the sand contractor has therefore to dredge sand from deposits in coastal waters not adjacent to the Hong Kong coastline under special arrangements made with the appropriate Chinese authorities. This year 1.22 million cubic yards out of total sales of 1.25 million was dredged from Mirs Bay near the mainland opposite Ping Chau Island, the rest coming mainly from stock. Special silica sand for industrial use is also sold at the standard price for direct collection by the pur- chasers from sites in the New Territories. The New Territories Administration charges a fee of $6.00 per cubic yard for small quan- tities of river or beach sand collected by villagers for village works.

6.70 There are six sand-selling depots, at North Point on Hong Kong Island, at Cheung Sha Wan and Kwun Tong in Kowloon and at Sha Tin, Tai Lam Chung and Silver Mine Bay in the New Terri- tories. These depots were open for business on 354 days during the year. In addition to the selling depots there is a sand storage site at Kennedy Town on Hong Kong Island.

6.71 Plans were made for reprovisioning the Cheung Sha Wan, Sha Tin and Tai Lam Chung sand depots at other sites as essential marine access to the existing ones is to be cut off by further works to be carried out seawards of the existing depots.

Laboratory

6.72 The establishments operated by the Quarries Section for testing construction materials include the main P.W.D. Laboratory at North Point and three branch laboratories, one at Farm Road in Kowloon and one at each of the Government quarries at Mount Butler and Diamond Hill. Testing of materials for the Public Works and other Government Departments and for the public is carried out at the North Point and Farm Road laboratories. The two quarry laboratories test the materials produced at these quarries.

6.73 The total number of tests carried out by the laboratories during the year was 78,358. Of the tests, a total of 8,792 were for private firms. The total number of tests is slightly less than in 1971-72, when more tests were carried out on concrete materials. There was a marked increase during the year in the number of soil tests carried out.

6.74 Various new items of testing equipment were purchased. The equipping of the Farm Road branch laboratory with further testing facilities, to improve the testing service for works on the mainland, continued.

STAFF, TRAINING AND WELFARE

!

Staff

6.75 There were still unfilled vacancies in the professional and technical staff grades throughout the year, despite constant recruitment.

6.76 Ten Engineers from overseas were recruited and one Royal Engineer Officer was on secondment from the British Forces. Six Assistant Engineers were promoted to full professional grade and four Apprentice Engineers were appointed Assistant Engineers.

6.77 A total of 12 officers, including 7 who each had over 20 years service, retired during the year.

Training

6.78 A Quarry Manager was on two-year attachment to Tarmac, Ltd. in England whilst one Engineer of the Drainage Works Division started a one-year post-graduate course in Public Health Engineering at the Imperial College of Science and Technology in October 1972.

6.79 A scholarship for twelve months was awarded by the Con- federation of British Industry, London to one Engineer of the Drainage Works Division to receive training under a Chartered Civil Engineer in the United Kingdom. A U.N. Fellowship was awarded to one Engineer of the Port Works Division, who attended a course on Indus- trial Complexes and Estates Development at the Asian Institute for Economic Development and Planning in Bangkok.

6.80 Eighteen engineering graduates of the University of Hong Kong were employed as Apprentice Engineers in P.W.D. under agree- ment for three years training in accordance with the regulations of the

Institution of Civil Engineers; others entered their final year. Their training in various offices was co-ordinated by the Technical Secretary of the Civil Engineering Office.

6.81 Seventy Foremen were recruited as a result of two intakes during the year and they attended 6-month full-time development training courses conducted by the Technical Training Unit, to be followed by 18-month in-service field training and supplemented by 4-year part-time day-release courses specially Organized by the Hong Kong Polytechnic.

Welfare

6.82 The Staff Welfare Officer was responsible for a wide range of services which included assistance offered to staff on applications for loans, legal aid, places in schools, short-term relief in emergency cases, housing problems, etc.

6.83 Joint Staff Discussion Groups on a Divisional basis continued to hold regular meetings with a view to maintaining and promoting mutual understanding and co-operation among all the staff of the Office.

6.84 Outings to Cheung Chau for staff of the office and their families were arranged and over 700 persons took part.

GENERAL

7.01 The demand for land for development continued during the year but the availability of suitable sites for such purposes diminished. This, allied to the flotation of a number of public companies, partic- ularly in the real estate field, resulted in very high prices being realized at public auction sales. The resumption programme in connection with Urban Renewal continued. A Lease Renewal Branch was formed during the year to cope inter alia with the renewal of many leases which expired last year and others which will do so next year. The provision and clearance of sites for all purposes and in particular in connection with Government's expanding development programme has resulted in an increasing workload on the staff of all Branches.

7.02 Included in legislation which was enacted during the year was the Crown Land Ordinance which supersedes certain provisions of Summary Offences Ordinance. The Crown Land Permits issued under the latter have been replaced by Crown Land Licences. The new Ordinance provides greater control over unoccupied Crown Land and facilitates the removal of illegal goods and squatters, functions which form part of the responsibilities of the Crown Lands and Survey Office.

7.03 By its intimate connections with land for all purposes, this office is closely involved both within the Department and with other Government Departments, resulting in considerable demands upon the time of Senior Staff for attendance at committees. The Weekly Land Meeting, with representatives of the Secretariat and the Registrar General's Department, the weekly P.W.D. Land Conference, and the fortnightly Building Conference and Crown Land Conference, handle all cases of sales of private land and special cases where the building on a site is controlled by lease conditions, as well as deciding or advising on policy issues and sites for major Government projects.

7.04 Land values continued very high throughout the year and revenue from sales reached the highest level for any financial year. A slightly greater number of lots were sold than in the previous year and revenue from land sold by public auction and tender increased to over $527 million as compared with $119 million in the previous year. One particular sale which took place in May, that of Inland Lot No. 8294 in Central District, realized $105 million. Several sites were sold for non-industrial use including the mandatory provision of a supermarket and such a site at Junction Road, Kowloon, realized $50 million. Indicative of the very high value of residential and non- industrial land during the year were two sites sold in Kowloon, one at Broadcast Drive and the other at Ma Tau Chung Road which realized $916 per square foot and $1,643 per square foot respectively. A small site in Cameron Road, Kowloon, with existing buildings standing on the lot, realized $2,748 per square foot. Competition for purchase of industrial land by public auction continued unabated, the highest price of approximately $231 per square foot being paid for a site in Chai Wan.

Urban Estate Division

7.05 The Urban Estate Division is divided into two sections, one each for Hong Kong and Kowloon. The Division deals with all sales, new leases and allocation of Crown land on Hong Kong Island and in Kowloon and New Kowloon, and the general administration and control of Crown land in the urban areas. During the year there were 86 lots sold by public auction or tender compared with 57 during the previous year. Trespass on Crown land by miscellaneous trades and the storage of goods continued to present some difficulties during the year although the policy of fencing sites and installing security guards was continued. It is, however, expected that with the introduction the new Crown Land Ordinance and the recruitment of non-professional staff to implement its provisions, clearance of Crown land will be carried out more quickly and without the need, generally, for litigation.

83

7.06 Apart from sales by public auction and tender, there was a continuing requirement for land needed for Government, institutional or community projects such as schools, hospitals, police stations, fire stations, low cost housing, parks and playgrounds. Land for these purposes is granted by private treaty or allocated to Government Departments and during the year 33 private treaty grants were made and there were 52 Government Land Allocations.

Property Management Division

7.07 The Property Management Division is responsible for the letting and management of premises owned but not occupied by Government and it conducts negotiations for the letting of Government buildings and piers which are not required for the time being for Government purposes or which are intended for non-Government use. It also manages buildings on former leased land which have reverted to the ownership of the Crown either through re-entry, expiry of the lease or purchase by agreement.

7.08 The Property Management Division is also responsible for the management on a temporary basis, pending sale, of those properties, or parts of properties, which have reverted to Government in the form of the Colonial Treasurer Incorporated due either to the failure of a former owner of a part interest to take up the offer of an assignment or because of a breach of user conditions.

7.09 The amount of rent collected during the year totalled about $8.98 million. Thirteen properties were taken under management, either for failure to pay instalments of premium or where the Crown lessees did not take up an offer of renewal of the Crown lease, 31 properties were disposed of by public auction sale where the sites were not required for public purposes, and 7 further properties were being processed for sale. In the Urban Renewal area 35 old properties were being managed at the end of the year. Demolition work commenced within Phase I of the Urban Renewal Pilot Scheme area, where 5 properties were demolished and demolition work was in progress in respect of 20 more. Towards the end of the financial year this Division was receiving a member of properties within the Yaumati and Wan Chai improvement areas and it is expected that this work will increase.

7.10 Approximately 220 properties were under management at the end of the year and this comprised a total of about 500 lettings. In addition 7 commercial piers and 18 ferry piers were managed and various wayleaves, licences, etc. issued. Co-operation was maintained

84

with the Registrar General's Department which advises on the legal aspects of the Division's work, with the Legal Department regarding court action and with the Buildings Ordinance Office from which, midway through the year, an experienced member of staff was seconded to this Division to help bring more urgent attention to necessary repair works. This has resulted in an improvement in the standard and speed of such work.

Valuation Division

7.11 The Valuation Division is divided into four sections, Records, Urban Renewal, Resumption and Modification. The Records Section records and analyses all sales of land in the urban areas of the Colony, and carries out continuous research into all factors that effect value of land, including current sale prices of flats and shops and building costs generally. The Section completed, during the year, 135 assess- ments of Incremental Value under the provisions of the Demolished Buildings (Redevelopment of Sites) Ordinance, and valued for Estate Duty purposes 966 properties with a total value of $257 million.

7.12 The Urban Renewal Section acquired during the year 39 properties at an aggregate cost of $4 million. Nine Resumption Notices were gazetted in respect of a further 77 properties, and evidence was given by expert witnesses before 5 Resumption Boards which sat during the year. Compensation awarded by Boards totalled $3.5 million. in respect of 28 properties.

7.13 The Resumption Section dealt with all acquisitions for public purposes outside the Urban Renewal Area. The Section acquired 2 properties by agreement for $0.5 million, 12 parts of sites for road widening purposes at a cost of $0.5 million, and completed 18 cases of grant of land in lieu of cash compensation, involving the grant of over 24,000 square feet of land. In addition, 5 Resumption Notice were gazetted in respect of 25 lots. Evidence was given by expert witnesses to 2 Compensation Boards, and compensation of $44,000 was awarded in respect of 6 lots.

7.14 The Modification Section deals with the interpretation of development conditions contained in Crown leases and the modification of such conditions where appropriate. It completed 91 transactions regarding modifications of lease conditions during the year, the premia collected amounting to nearly $14 million.

LEASE RENEWAL Branch

Government Land Agent:

J. P. POTTER, J.P., F.R.I.C.S.

T. D. PETTY, F.R.I.C.S.

7.15 This Branch was formed during the year to deal with the valuation problems involved with the renewal of the leases of some 5,000 lots and sections in New Kowloon, the leases of which expire in June 1973, together with the lesser number of renewable leases which will annually expire both in New Kowloon and elsewhere. All these leases were subject to a right of renewal at a fair and reasonable rental value of the ground as at the date of renewal. The position was complicated owing to the fact that a considerable number of the properties held on renewable leases had been sub-divided into thousands of undivided shares which make it extremely unlikely that all the owners would be able to get together in order to exercise their right of renewal. In order to solve this problem, proposals were formulated for legislation which would have the effect of renewing all these leases automatically by statute, and for amendment of the Crown Rent and Premium (Appointment) Ordinance so as to ensure that reassessed Crown Rent was equitably apportioned between the undivided share owners according to the value of the shop or flat that each share owner owned.

7.16 Two sections were employed continuously on preliminary work for the valuation of some 5,000 individual sites. This work was complicated by the fact that during the year there was a considerable increase in the value of land generally throughout the Colony. Towards the end of the year the prices being paid for land were influenced by the ready availability of public investment through flotations of shares of real estate companies forecasting dividends at fairly modest rates of around 7%. It became apparent that to assess rents based upon the level of value thus established would not necessarily result in a 'fair and reasonable rental value of the ground', and accordingly a recommendation was made to the Government that the values for the purposes of renewing the leases in New Kowloon expiring in 1973 should be pegged to the values obtaining at 1st July, 1972.

7.17 Regrants of 84 non-renewable leases were completed, involving premia of nearly $19 million (paid in a lump sum) and premium instalments of nearly $7 million. The renewal of 92 leases was

86

completed, the majority being renewed early at the request of lessees; the reassessed Crown Rent was nearly $4 million per annum.

SURVEY BRANCH

Government Land Surveyor:

J. T. Cooper, F.R.I.C.S., F.R.G.S. G. J. BENTLEY, M.I.S. (Aust.) (Acting)

7.18 The Survey Branch consists of two Divisions, Hong Kong and Islands Survey and Mainland Survey. Functionally, the work of the Branch is divided into four main categories:

(a) Control Survey-The provision and maintenance of the rigid framework of fixed points, on both horizontal and vertical planes, on which all surveys are based, viz., triangulation stations, traverse stations and level datum bench marks.

(b) Mapping Survey-Surveys for the preparation of plans and maps of the whole Colony at different scales and their sub- sequent revision at regular intervals.

(c) Title Survey-The delineation and recording of all property boundaries in the urban areas (and in planned areas of the New Territories) and surveys for grants, sales, exchanges, Crown Leases, surrenders, etc.

(d) Cartography-The production of plans and maps at various scales for all purposes and their subsequent official distribution and public sale. The main cartographic sections and their supporting photo-reproduction section are in Murray Building and form part of the Hong Kong and Islands Division.

General

7.19 This year saw a reversal of last year's trend of increased land dealings requiring title surveys and the number of plans produced for this purpose decreased by approximately 18%. This released a number of survey parties, a few of whom were assigned to check the large-scale mapping of Mass Transit station sites carried out by Consultants, while most were diverted to assist with the revision programme, where considerable arrears had accumulated.

7.20 Following the completion of all large-scale mapping based on the photography provided by the contractors, photography has been

87

Digitized by

Google

undertaken with the RC10 camera to assist in the revision of certain areas in the New Territories using a recently developed method of field control combined with comparision of photography enlarged to plan scale. This has helped to speed-up 1/1,200 scale revision, and it is expected that revision of additional areas will be covered as part of the proposed new photogrammetric contract.

7.21 The accurate control system established for fixing points on the alignment of the Mass Transit scheme was broken down further and is now being incorporated into the entire control traverse network in the urban areas. Check surveys on Mass Transit site plans plotted to 1/200 scale, carried out by two firms of private surveyors for the Consulting Engineers, were completed by staff of the Control Section.

7.22 The large-scale survey plan redrawing programme was dras- tically curtailed during the latter half of the year, pending introduction of the new metric (S.I.) scales on which much effort was expended on sheet and specification design as well as production planning. Title drawing work was rather surprisingly down on production over the year, while the Photo-reprographic and Sales sections had record productive years.

Control Survey

7.23 Following closely on the traverses established to the maximum degree of accuracy along the proposed Mass Transit routes, the use of Electro-magnetic Distance Measuring Equipment has enabled re- measurement of existing control traverses and the fixing of new control traverses to be tied in quickly and accurately to this Mass Transit control.

7.24 An increased amount of control traversing was established in the New Territories to assist in the revision plans of developing areas and as a basis for the fixing of photo-control points in areas being plotted by photogrammetry from aerial photography. Permanent marks were also established in certain areas where the proposed New Town development is considered to have priority requirement.

Mapping

7.25 The number of 1/600 scale sheets fully revised decreased by about 5% this year but the number of 1/1,200 sheets fully revised. showed an increase of more than 30%. This substantial increase in

88

Digitized by

Google

production is due to three main factors, the additional staff gained from the title sections where work had fallen off, the new simplified specifications for 1/600 and 1/1,200 scales, which are expected to have an even greater impact next year, and the use of new methods of survey made possible by modern equipment such as electro-magnetic distance measurers and radio-telephones.

7.26 Three additional electro-magnetic distance measurers have recently been delivered and a fourth with a much longer range is on order and is expected to arrive next year. These instruments greatly simplify the provision of control points required for revision and should further improve the production rate in 1973-74.

Title Survey

7.27 The demand for boundary surveys declined during the year under review but again showed a sharp increase during the last quarter and the arrears at the end of this period were approaching a record high level, exceeded only during the third quarter of 1971-72. Should this trend continue the Survey Branch will again find itself under severe pressure and longer delays in carrying out title surveys may result.

7.28 Work has continued on calculating the intersection points. where the Mass Transit reserves cut the boundaries of lots about to be developed or re-developed, in order to protect the proposed rail route during piling operations, etc. This data is then available to the owner/developer as part of the relevant dimensioned or setting-out

plan.

Local Air Survey

7.29 Photography for plotting purposes, using the RC10 air survey camera, commenced in April and continued at a steady pace during the year. Plotting of many sites, for the Engineering and Architectural Offices, has been carried out under contract in the United Kingdom. Vertical photography was provided following the rain storm damage of June, and was used for planning remedial works in the disaster areas and as a record for the Commission of Enquiry. This work and oblique photography from a helicopter placed a very heavy work- load on the photographic and reprographic staff of this office.

89

Digitized by

Google

7.30 It has been found that the availability of aerial photography has resulted in a demand for this facility, from all offices interested in engineering and land development, far in excess of that anticipated. In addition, requests for air photography have arisen in connection with those projects being dealt with by several firms of Consulting Engineers appointed by Government, and this too has placed an increased work-load on the limited air survey and reprographic staff available at present.

7.31 Local Professional and Assistant Professional Land Survey Staff have been undergoing training in the operation of the RC10 camera during the latter half of the year and this will continue until the Air Survey Unit has a number of navigator/camera operators capable of performing this work. Navigation of the 'Islander' aircraft during photographic runs has been greatly assisted since the installation of the NF2 Navigation Sight in January.

7.32 Draft proposals for a new Photogrammetric Plotting Contract were circulated to a number of international air survey firms, and it is expected that tenders for this contract will be called later in 1973.

Cartography

7.33 Work at the two basic scales of 1/600 and 1/1,200 for basic mapping was restricted during the year to the addition of metric grids and conversion tables, and revision work to existing master trans- parencies. The cartographic specification and design of sheet format for the proposed new 1/750-1/1,000 dual-scale series was virtually completed.

7.34 Some of the pressure on the Cadastral and Land Registration Plan sections showed a small but welcome decrease during the year. This respite enabled staff on loan from other sections to return to their normal duties and enabled some redrawing of Land Records to proceed.

7.35 The 1/2,400 series was maintained on a revision basis during the year. Production of 1/4,800 sheets therefrom ceased pending a decision to adopt 1/5,000 scale.

7.36 The first pilot sheet at 1/5,000 is virtually completed. This series will be produced by direct photo-reduction of the 1/2,400 series with new contours at 10 m. vertical interval. Full production for the urban areas will commence during the next year.

7.37 The 8 inches to 1 mile series was not revised since it is intended to commence its replacement with a new 1/10,000 (about 6 inches to 1 mile) series. However, the feasibility sheet was not a great success and further discussion led to the preparation of a new pilot sheet at 1/7,500, production of which will commence during the next year.

7.38 The production of revised 1/10,000 series L884 dual-language editions continues on a limited basis. As with all map scales, the future of this series is affected by metrication, since, although 1/10,000 is an S.I. scale, it is plotted to Imperial grid values and has Imperial contours. Ten sheets were revised, printed and distributed during the year, two sheets were with the printer and a further six were under revision at the end of the period. The actual revision of these sheets is now largely a drawing office function undertaken by Cartographic Assistants from the up-to-date air photographs.

7.39 Repro-material of the four component 1/10,000 sheets for one further 1/25,000 Series L882 sheet was forwarded to the Director of Military Survey, United Kingdom, for the production of a second Edition of that scale. Demand for these maps remains heavy. Arrange- ments have just been finalized to reprint locally all the sheets for which no second Edition is expected within the next year, comprising 17 sheets and a total of 27,500 prints.

7.40 The rate of miscellaneous work for all sections of Crown Lands and Survey Office, for other departments and for public sale, has increased to such an extent that two posts have been created to cope with it in the coming year. It includes serial photograph indexing and the preparation of index maps thereof, simplified grid reference booklets, various indices for metrication and contract mapping policies, maps for Police, Defence Branch, General Post Office, Mass Transit etc., and the preparation of several wall maps for various heads of departments.

7.41 The metrication of the two-sheet 1/50,000 HK1 series is well in hand. During the next year it is intended to print a new metric edition in two versions, one with elevation tints, hillshading and 50 m contours and an unlayered version with 25 m contours. The detail revision remains to be completed. Stocks of the reprinted second Edition (3,600 sheets) are expected to last till October 1973.

7.42 The 1/100,000 L681 military series will be replaced by a Hong Kong produced dual-language metric version based largely on the map currently completed for the second Edition of the Hong Kong Official Guide Map.

7.43 The folded, doubled-sided, dual-language Hong Kong Official Guide Map, published in May, has proved popular and is now sold out (10,000 copies). A revised and improved second Edition, under urgent preparation, is now at proof correction stage and should be printed in the near future.

7.44 Sheet 2 (New Territories West) the Countryside Series has been in production for most of the year, but has become delayed due to non-availability of field staff for footpath checking. This is now being undertaken by Cartographic staff using air photographs. Its completion date is difficult to forecast but, it is hoped, will be within 1973.

7.45 New end-plate maps were produced for both Chinese and English versions of the Annual Report in its new larger format. The same plates will be used for the production of a separate map at 1/200,000.

7.46 Sales, direct to the public and indirectly through retailers, increased by 60% over the previous year and are three times larger than in 1970-71. These totals take no account of the many hundreds of maps held and sold at the Government Publications Centre which are accounted as issues by this office. This large increase in sales and distribution has created heavy pressure on the staff of this section. The advent of RC10 aerial photography has also increased the demand on the services of this section, which has to explain the coverage to potential users. Furthermore, the many consultants and contractors working on Government projects make continual demands for urgent photographic work in connection with their own projects.

7.47 The Planning Sections, which are expanding, of Cartographic Assistants working under the direction of Planning Officers, are technically overseen by the senior cartographic staff of Survey Branch. Statistically, production was slightly down on previous years due largely to the fact that the products are increasingly complex and involve more man-hours in production. Details of the work produced are included in the report concerning Planning Branch.

7.48 The Photo-reprographic Section was completely re-organized during the year, which saw the installation of the large format precision process camera and construction of additional accommodation. The difficulty of delivering the base of the camera to the 21st floor of Murray Building was overcome with the help of the R.A.F., who lifted it by helicopter during May. Structural modifications, and the supply of electrical, water supply, drainage and air conditioning services for the camera, ancillary equipment and processing rooms were delayed for many reasons and the unit did not come into produc- tion until January. However, the section is now fully equipped and should now be able to cope with any demand normal to map produc- tion as well as the additional demand brought about by metrication, which will increase during 1973-74. The accuracy and performance of the camera have so far exceeded expectations and its reliability should prove equally good.

7.49 Overall print production was the highest ever recorded for a 12 month period, representing a 12% increase over the previous period. This can be attributed largely to the unprecedented demand for photo- graphic records and evidence of the June rain disasters, the advent of high quality aerial photography and the increasing demand for survey and layout plans, particularly from consultants and development companies.

7.50 The second exhibition of maps was held in the Ocean Terminal from 23rd-28th May and opened by the Hon. SZETO Wai. Public response was encouraging and nearly $20,000 was realized from sale of maps within the exhibition hall,

Development Programme. It prepares plans for the existing and future urban areas, including new towns, and planning guides for rural areas. It is also very much involved in the preparation of urban improve- ment schemes in the older urban areas. The work of the branch is undertaken by three divisions, namely, Colony Planning, Urban District Planning and New Territories District Planning.

Colony Planning Division

7.52 This division is divided into two sections, Colony Planning and Design and Layout. The functions of the Colony Planning Section include the revision of the Colony Outline Plan, the up-dating of the data bank on which it is based and the preparation and updating of the 10-Year Development Programme. The division carries out land use, constructional, occupancy and other special surveys for planning purposes. The information obtained is analysed within the framework of tertiary, secondary and primary planning units and planning periods in order to correlate land use and demographic data. The division prepares background studies which set out the existing conditions and future requirements in planning areas and thus ensures the integration of district and Colony Planning. It also carries out special studies and supplies information and reports to the Housing Board, Town Planning Board, Hong Kong Advisory Committee on Recreational Development and Nature Conservation and other advisory committees and Govern- ment Departments. It also prepares planning guides for rural areas in the New Territories in consultation with the New Territories District Planning Division and the New Territories Administration.

7.53 The Design and Layout Section services the District Planning Divisions and prepares layouts for new development areas throughout the Colony. It also advises on major private development proposals.

Urban District Planning Division

7.54 The Urban District Planning Division deals with district planning in the urban areas, i.e. Hong Kong Island, Kowloon and New Kowloon. It prepares draft outline zoning plans for the Town Planning Board and departmental, outline development and layout plans for the Land Development Planning Committee. The division is responsible for development control and the reservation of sites for Government Departments and utility companies and other purposes.

New Territories District Planning Division

7.55 The New Territories District Planning Division covers the whole of the New Territories. It is responsible for the preparation of draft Town Planning Board plans for the new towns and other areas in the New Territories and departmental, outline development, layout and outline zoning plans for Land Development Planning Committee. The division is responsible for advising the New Territories Adminis- tration on development control and reservation of sites for Govern- ment Departments, utility companies and other purposes in the New Territories.

Town Planning Board

7.56 The Town Planning Board met on 13 occasions and considered 24 papers and draft outline zoning plans for 6 planning areas in the urban areas and 2 in the New Territories.

Land Development Planning Committee

7.57 The Land Development Planning Committee, which is respon- sible for advising Government on departmental proposals, considered 42 papers presented by the Planning Branch. Items considered included outline zoning plans, layout plans, planning guides for rural areas, provision of open spaces, revision of the Colony Plan and preparation of the Colony 10-Year Development Programme.

Advice on Development Schemes

7.58 Planning advice given on public and private development projects increased substantially during the year. This was particularly noticeable in the New Territories.

Liaison

7.59 The planning and co-ordination functions of the Branch require extensive consultation with other Departments, utility com- panies, organizations and the public. The Branch was represented on Town Planning Board, Housing Board and numerous committees such as New Town Works and Management Committees, Roads Committee, Recreational Development and Nature Conservation. A circular listing all statutory and departmental plans, most of which can be purchased on application to the Cartographer, was issued quarterly to depart- ments, public utility companies and certain non-Government organiza- tions.

Staff

STAFF, TRAINING AND WELFARE

7.60 The total authorized establishment amounted to 1,071 persons, an increase of 60 over the previous year. The office continued to recruit professional staff for the New Territories Administration and the Civil Engineering and Highways Offices.

7.61 Eleven Estate Surveyors and two Land Surveyors were appointed on contract during the year. Local officers continued to be recruited and received in-service training, and in this category six Assistant Estate Surveyors who became professionally qualified were promoted to Estate Surveyors and two Surveying Assistants (Estate) were promoted to Assistant Estate Surveyors. Two non-expatriate Assistant Land Surveyors were promoted to Land Surveyors and four non-expatriate Assistant Planning Officers were promoted to Planning Officers. During the year one Chief Estate Surveyor and five Estate Surveyors resigned, one Senior Land Bailiff retired and one Land Surveyor left Government service on completion of his contract.

Training

7.62 Surveying Assistants (Land, Engineering, Estate and Planning) are mostly young men with the appropriate academic qualifications, often recruited immediately after leaving school. They all join the service initially at Class III level. Surveying Assistants (Land and Engineering) attend a comprehensive course in land survey for 8 months, while the Estate and Planning streams attend a shorter course. Thereafter, the Surveying Assistants (Engineering) are attached to various functional survey sections for field and practical experience for a period of 12 months before being posted to one of the engineering offices for further in-service training. Surveying Assistants (Land, Estate and Planning) do the whole of their in-service training in Crown Lands and Survey Office. At the end of 34 years, Surveying Assistants of the four streams sit for a promotion examination and, subject to passing this and satisfactory service, are promoted to Class II at the end of four years.

7.63 Officers recruited in the Surveying Assistant grades, although not pupils, are, subject to holding the necessary academic qualifica- tions, able to take professional examinations. In the 1972 Royal Institu- tion of Chartered Surveyors examinations (Land Surveying Division), two Surveying Assistants (Engineering) passed the Intermediate and

7.65 A limited number of entrants who have academic qualifications to become Students of the Royal Institution of Chartered Surveyors are recruited as Student Estate Surveyors and encouraged to take a correspondence course and to attend evening classes at the Hong Kong Technical College. Student Estate Surveyors, who were preparing for the Final examination, were permitted to attend a day-release course at the Hong Kong Technical College on one day each week. There were six officers undergoing this form of training during the year. Five students passed the Intermediate examination (General Section) of the Royal Institution of Chartered Surveyors.

Overseas Training

7.66 Three Assistant Planning Officers were awarded Government Scholarships for two-year post-graduate town planning courses at Universities in Australia; one returned after successfully completing a similar course. One Assistant Estate Surveyor and one Student Estate Surveyor began a twelve-month training attachment to the Estates and Development Valuer, Plymouth and one returned after completing a similar attachment.

8.01 This Office continued to be responsible for the electrical and mechanical engineering of Government projects, with the exception of Waterworks projects. Just prior to the end of the year, pumps and pumping systems and emergency generators for Building Services Projects also became the responsibility of this office. In addition, air conditioning, mechanical ventilation, refrigeration, cold stores, pump- ing stations for air conditioning installations and filtration plant for swimming pools are now referred to this office to ensure adequate provision for operation and maintenance facilities.

8.02 The office provides a service to other Departments and other offices of the Public Works Department, acting as consultants and contractors on electrical and mechanical matters, including the main- tenance of most of the equipment used by Government and the whole of its fleet of 3,499 vehicles.

8.03 During the year a detailed study of the Workshops organiza- tion was completed and certain proposals made and adopted to accommodate the changing and increasing workload and to provide a service for Government Departments which would be simultaneously effective, timely and economical.

8.04 The Progress and Planning Sub-Division, working in liaison with the workshop re-organization, introduced new working procedures in various Sections, conducted feasibility studies into the use of various proprietary products, and revised existing procedures to reduce massive documentation and associated clerical effort. It is to be regretted that the activities of this Sub-division were, to some extent, limited due to the staffing situation where resignations outpaced recruitment. This was due to higher salary inducements offered in the private sector.

Passenger boarding bridges for aircraft parking bays, the installation of apron floodlights, inner and outer taxiway, link taxiway and south taxiway turn-off circuits and associated work, together with the installation of an additional sea- water pump for the Terminal Building Air conditioning Plant, were in hand at Hong Kong International Airport.

Lifts and Escalators

8.10 There are now 8,627 lifts and 152 escalators in use in the Colony. 9,854 certificates in respect of examinations and tests of safety equipment were issued and 33 investigations made into lift accidents, unregistered lifts and complaints by the public.

OPERATIONS AND MAINTENANCE DIVISION

Chief Electrical and Mechanical Engineer:

G. J. OSBORNE, C.Eng., F.I.Mech.E., M.B.I.M.

8.11 For the purposes of the operation and maintenance of major plants, specialist electrical and mechanical services and the maintenance. of the Government's fleet of 3,499 vehicles this Division is split into five sub-divisions each responsible for a certain aspect of the Division's overall responsibilities.

8.12 The Progress and Planning Sub-Division is responsible for co- ordinating the activities of both major workshops, their detachments

and the Military Works Sub-division with regard to job control systems, overhaul programmes, control of spare parts, and cost effectiveness of repair operations, including repair standards, manpower utilisation and work evaluation, utilization of workshop space and machinery, standardization of working procedures and maintenance records.

8.13 The Workshops and Maintenance Sub-Division consists of two main workshops located at Caroline Hill Road, Hong Kong and Sung Wong Toi Road, Kowloon and four Vehicle Service Stations at Kennedy Town, Lantau Island, Lai Chi Kok and Fan Gardens. The Sub-division is broadly responsible for the maintenance of vehicles, electrical, air-conditioning, refrigeration and other electrical and mechanical plant and equipment.

8.14 The Vehicle Design and Procurement Sub-Division is respon- sible for the preparation of vehicle and mobile plant specifications, including specialized plant and equipment, the design of non-standard vehicle bodies, co-ordination of Government's annual vehicle require- ments, contracts for vehicle bodywork construction, bodywork repair and repainting, construction of refuse handcarts and bulk containers and the supervision of such contracts. The sub-division is also responsible for the Transport Pool within the Government fleet.

8.15 The Operations Sub-Division is responsible for the operation and maintenance of major plant and is sectionalized into Incineration Plants and Abattoirs, Air Conditioning Plants, Airport Services, City Hall and Hospital Services. The majority of the plants are required to provide a 24-hour year-round service.

8.16 The Military Works Sub-Division, headed by an officer of the Royal Engineers on secondment, is responsible for the operation and minor maintenance of non-combat electrical and mechanical equipment in Royal Naval, Army and Royal Air Force installations, barracks and some 3,500 services married quarters and hirings in the Colony. This involves the operation of Cold Stores, Boilers, Pumping Stations, Swimming Pools, Generators, etc., and the maintenance not only of the above facilities but also of Switchgear, Air Compressors, Workshops Equipment, Grass Cutters, Cookhouse Equipment and a wide range of Domestic Equipment in married quarters. In all over 60,000 items are involved, including 5,300 refrigerators and over 50,000 items of domestic equipment such as fans, cookers, water heaters, irons and vacuum cleaners. Major maintenance is now undertaken by the main Workshops on behalf of The Military Works Sub-Division.

PROGRESS AND PLANNING SUB-DIVISION

8.17 At the beginning of the year authority was given to establish this Sub-division on a permanent basis. Although every effort has been made to bring the staff up to strength, resignations have outpaced recruitment. However, with the help of Apprentice Engineers and Technical Apprentices undergoing training in carefully selected areas of projects, the initial work of the Sub-division has been maintained and consolidated.

8.18 With the exception of the Vehicle Section of the Kowloon Workshop, new working procedures have been introduced in all sections of the E. & M. Office Workshops, including Kennedy Town, Lai Chi Kok and Lantau Vehicle Service Stations, Fan Gardens Depot and the Parking Meter Workshop Section at Caroline Hill.

8.19 The routine work of the section continued with the aim of planning, progressing and analysing repair loads while maintaining a satisfactory repair and maintenance service to client departments at minimum cost.

8.20 Savings have been effected during the year through reorganiza- tion of the use of reconditioned and reusable vehicle engines leading to a considerable reduction in contract repair costs. The availability of Government vehicles was improved by a number of measures but a useful improvement also resulted from tighter control on completed vehicles awaiting collection. The recycling of stocks of domestic refrigerator and electrical appliances held in Government Supplies Department has reduced the necessity of purchasing new replacement equipment resulting in substantial savings in capital expenditure.

8.21 Close liaison with Government Supplies Department continued throughout the year with E. & M. Office staff being responsible for the local purchase of non-standard spare parts, all standard items being obtained by Government Supplies Department staff.

8.22 Spares holdings continued to be reviewed, stock lists regularly updated and dead stock eliminated, thus reducing the amount of capital tied up in spares and ensuring higher utilization of storage space.

WORKSHOPS AND MAINTENANCE SUB-DIVISION

8.23 In addition to the maintenance of Government's vehicle fleet this sub-division regularly inspects, repairs and renovates almost all

105

the electrical and mechanical equipment used by Government. This work ranges from electro-medical devices to high voltage distribution, from bicycles to refuse collection vehicles, from rice cookers to road- making plant. The workload of the workshops has increased in step with the expansion of Government activity and new Government services and although the average rate of expansion was 12% per annum over the period 1963-1971 the corresponding average rate of increase of the work force has been held to 7%.

8.24 To accommodate the changing and increasing workload, organization structures were adapted to meet each change or increase but it was not until 1971 with the recruitment of additional professional staff that it was possible to survey the whole structure with a view to effecting improvements by a general re-organization of management while introducing new systems of planning control.

8.25 On the basis of the information derived from the survey a completely new management structure was designed. In this, proposals for higher grade staff for managerial and supervisory staff were accompanied by a reduction in the total number of staff.

8.26 These proposals were approved with effect from 30th August, 1972 and the process of reorganization commenced. The original Vehicle, General Engineering, Electrical and Air-Conditioning and Refrigeration Workshops have been reorganized into three Sections, namely Electrical, Mechanical and Vehicle. At the same time the workload on each Section was rationalized in order to concentrate skills, and the number of management levels reduced so that better communication would be achieved between top management and shop floor personnel, giving each Chargehand, Foreman, Supervisor and Section Manager a manageable span of control.

8.27 Quality Control and Production Control Systems to assist and support the line management at all levels, and Method Study and Training Service functions so that best use can be made of the avail- able resources, were set up towards the end of the year and are still in the course of development and trial operation.

Electrical Sections

8.28 These Sections, in Hong Kong and Kowloon, each under a Section Manager, are now divided into four sub-sections. The Refrigerator and Room Cooler Workshops are responsible for the

106

delivery and collection, overhaul and major repair of refrigerators and room coolers, and also the testing of these and other items of new electrical equipment. The Site Maintenance sub-sections are respon- sible for on-site maintenance, overhaul and preventive maintenance of electrical equipment, room coolers and refrigerators. The Electrical Workshop sections are responsible for attending fault calls in respect of such equipment, its overhaul in workshop and electro-mechanical fitting work and the repair/rewinding of electric motors. The Traffic Light and Installation sub-sections are responsible for the installation, modification, maintenance and repair of traffic light signals and aids (including a night patrol of such equipment), the installation and wiring of new equipment and also temporary lighting.

8.29 During the year these Sections carried out tests of 28,610 items of new equipment, of which 1,426 were room coolers, for the Government Supplies Department and other Departments. New room coolers and domestic refrigerators totalling 273 were installed and 3,170 of these items completely overhauled. Preventive maintenance. was carried out on 34,369 items of electrical equipment and 6,573 inspections of contract-maintained room coolers carried out. Domestic refrigerator cabinets totalling 1,670 were re-sprayed, 3,708 electric motors of various sizes overhauled and 45,522 fault calls attended. In addition, lighting facilities were installed in pedestrian subways, electric wiring installed for various machines and equipment, defec- tive cables renewed, control equipment for steam boilers, pumps and other equipment installed and numerous other electrical installations carried out.

Vehicle Sections

8.30 These Sections are divided into units, each being responsible for some part of the maintenance, repair and overhaul of a vehicle. The various shops undertake the inspection, servicing and repair of Government's vehicle fleet, including motor cycles. The Sub-assembly Shop deals with the reconditioning and test of engines removed from vehicles, the major overhaul of gearboxes, clutches, axles, steering boxes, suspension and brake components. Body, Sheet Metal and Carpenters Shop are very fully engaged on the construction and repair of bodywork. The Upholstery Shops repair vehicle upholstery, including the re-lining of roofs and door panels and also make all canvas canopies, carpets, rubber seats and seat covers for vehicles. Tyres and tubes are repaired, electrical systems are maintained and

rewired and batteries are serviced in other subsidiary shops. The Paint Shop in the Caroline Hill Workshop not only deals with complete vehicle respraying but also the painting of electrical appliances and other miscellaneous items, although it has been necessary to have some of the vehicle respraying work carried out under contract. In Kowloon the lack of workshop space necessitates not only all whole- vehicle respraying but also all major vehicle body repairs being carried out under contract. The cost of such work by contract continues to rise but in the circumstances of current Workshops congestion this additional cost has to be accepted. In Kowloon room is available for only domestic equipment to be painted and small re-touching jobs carried out on vehicles.

8.31 During the year these Sections completed 86,608 Works Orders, which included the major overhaul of 926 vehicle engines and 143 vehicle bodies. Servicing action was carried out 18,084 times, 1,470 accident and 10,537 breakdown repairs were carried out, 262 vehicles were repainted in the workshops and 13,113 other paint jobs were performed. Repairs to 638 refuse handcarts and litter bins belonging to the Urban Services Department and 72 bicycles were carried out. Also completed were 2,424 upholstery repairs and 2,831 carpentry tasks. In the Welding, Blacksmiths and Tinsmiths Shops were completed 12,717 jobs for these and other Sections. Under contract 79 vehicles were repainted, body repairs were carried out on 157 vehicles, modifications carried out on 74 vehicles and bodies constructed for 53 vehicles.

Mechanical Sections

8.32 These Sections, one each in Hong Kong and Kowloon, consist of what were previously known as the Plant, Steam, General Engineering and Drainage Shops and are now divided into only two sub-sections, Heavy Plant and Steam, and General Engineering.

8.33 The Heavy Plant and Steam sub-sections are now responsible for the installation and maintenance of generators, pumps, steam boilers, swimming pool filtration plants, oil fuel systems, autoclaves, sterilizers, compressors and mobile plant such as road rollers.

8.34 The General Engineering sub-sections are now responsible for milling, turning and grinding of components of machinery, instrument fitting, engraving, small engines and gardening equipment, hydraulic

systems other than those used in the propulsion of vehicles, laundry and dental equipment, school equipment, printing and post office machinery and the installation and maintenance of masts and aerials.

8.35 During the year the staff of these sections completed 49,245 Works Orders which included the installation, testing and commission- ing of 403 water pumps and emergency generators, 8,561 tasks carried out by the machine shops, fitting shops and instrument shops, 169 tasks carried out by the riggers, 6,214 tasks (140 orders) by the engraving shop and the general maintenance and overhaul of plant and equip-

ment.

Parking Meter Section

8.36 This Section operates a main workshop at Caroline Hill and two depots, one each in Harcourt Road, Hong Kong and Government Offices Building, Canton Road, Kowloon. The main workshop carries out complete overhauls of meter mechanisms, the re-conditioning of casings and the painting of casings and brackets. The staff at each depot attend fault calls and carry out minor repairs. Where they are unable to effect a repair the meter is changed (for which purpose a stock is held at each depot) and the defective meter returned to the main workshop for overhaul. Thus the Section is responsible for the installation, servicing and maintenance of all parking meters through- out the Colony.

8.37 Additional staff was approved about the middle of the year to implement the scheme to extend the operational hours of parking meters until mid-night. This scheme, which was put into effect on 1st October, 1972, has necessitated the conversion of the instruction plates on each meter and by the end of the year 2,414 plates had been converted to cover the new hours.

8.38 At the end of the year there were 7,009 parking meters in operation. During the year 157,280 meter faults were attended, which represents an increase of just over 7% over the previous year's figure. 65% of these faults were caused by attempts to use foreign articles instead of the correct coins. A total of 8,915 meters were cleaned and overhauled, 7,166 mechanisms changed, and 580 new meters installed; 980 meters were removed and 447 re-installed; 2,000 new meters were time-tested.

VEHICLE DESIGN AND PROCUREMENT SUB-DIVISION

8.39 During the year 614 new vehicles, ranging from motor scooters to refuse collectors, were received and put into service, while 410 vehicles were withdrawn from service. Body and construction work completed on vehicles during the period under review included a cemetery van, 2 condemned meat vans, a prison van, a 50-seater bus, 5 meat vans, 2 Police Command Posts, an explosives lorry, a Health Van, a mobile Immigration Office and 22 covered lorries. Modifica- tions carried out included 9 street washing vehicles, 171 Ford Transit vehicles and 8 meat vans. Protective screens were fitted to 117 Police Vehicles, Ambulances and certain Government Saloon cars. Ten 9- seater buses were modified for use as temporary ambulances. Con- tracts were let for body building, modification, repair and repainting in respect of 492 vehicles. Over 300 refuse bins, steel trolleys and refuse handcarts were manufactured.

8.40 The 50-seater bus was to a completely new design and com- pared favourably with similar coaches in the private sector. The meat vans saw the introduction of the container principle where to achieve greater vehicle availability the chassis and body are separate units. Both the bus and meat vans received favourable press comment. The year also saw a breakaway from long established methods of body construction and the introduction of non-corrosive all aluminium skinned bodies. Also specialist-designed to meet the particular needs of Hong Kong was a 2 berth ambulance based on a standard Ford Transit body. This ambulance has proved extremely popular in use due to its comfort and mobility.

Transport Pool

8.41 The 143 vehicles of the Government Transport Pool made 30,363 trips during the year. In addition, there were 15,668 commercial vehicles hired to supplement pool transport. A total of 976 motor drivers (including servicing officers) were tested, 649 being passed, and 163 motor drivers were engaged. Government vehicles of all Depart- ments were involved in 1,470 accidents.

Also at the request of the Fire Services Department this Office was required to provide emergency lighting at the Kotewall Road disaster site. The Office co-operated throughout the year with the various practice crash exercises held by the Civil Aviation Department.

PLANT OPERATION

Incineration Plants, Abattoirs and Compost Plant

8.43 The Kennedy Town Incineration Plant operated continuously throughout the year until 1st March, 1973 when it was shut down for overhaul, the first in two years. Prior to the shut-down certain modifications and replacements of machinery were carried out with a resulting improvement in burning. Both boilers were surveyed at the beginning of the year. During the shut-down major work was carried out on renewing the whole of the top of the cold gas duct, a large section of the division plate, all deflector vanes and forced draught inlet dampers, and the refractory in the hot gas duct. In the incinerator units the only major repairs were the renewal of all incinerator bye-pass arches. Both waste heat boilers were opened up, cleaned internally and externally, all mountings refitted and the boilers surveyed. At the end of the year the overhaul was continuing on all ancillary machinery including cranes, conveyors, fans etc. Refuse burnt during the year amounted to 184,850 tons. In addition to routine maintenance 990 mechanical and 359 electrical repairs were carried out. The use of the high pressure water jet cleaner has brought about a saving in the time taken on cleaning the grit collector and the external parts of the boiler and in addition a far better cleaning has been achieved.

8.44 The Lai Chi Kok ‘A' Incineration Plant was shut down for two weeks in January 1973, otherwise it, too, operated continuously throughout the year. Modifications to boiler superheaters were completed early in the year and the turbo-alternator put on load. Modifications to the cooling system are under review due to the blockage, by pollution, of the sea water strainers and condenser tubes of this unit. In order to prolong their life the superheater tubes have been sprayed with a ceramic coating. An evalution of this coating. was continuing at the end of the year. Refuse burnt during the year amounted to 220,690 tons. In addition to routine maintenance 705 mechanical and 75 electrical repairs were carried out.

8.45 The Kennedy Town Abattoir plant continued to operate smoothly throughout the year and the annual overhaul of all equip- ment was carried out on a ‘one-line-at-a-time' basis during the first quarter. An extension of the By-Product Plant is in the design stage and is being handled by the Design and Projects Division of this Office. During the year 367 mechanical and 287 electrical repairs were carried out in addition to routine maintenance.

8.46 The Cheung Sha Wan Abattoir also continued to operate smoothly throughout the year. Night slaughtering was commenced on 1st November and additional staff was approved to cope with this. With night slaughtering it has been possible for major maintenance to be carried out on a 'one-line-at-a-time' basis. During the year 570 mechanical and 537 electrical repairs were carried out in addition to routine maintenance.

8.47 Compost was not produced from the Lai Chi Kok Compost Plant and towards the end of the year it was decided that the Plant, due to lack of demand for the product, be shut down permanently with a view to its being disposed of.

Air-conditioning and Refrigeration Plants

8.48 These Sections maintain all air-conditioning plants including associated water pumps with chlorination equipment and refrigeration plants. At the end of the year 287 air-conditioning plants totalling 15,629.15 tons of refrigeration were in operation. This figure includes 62 plants which are the property of H.B.M. Department of the Environment and which are maintained by this office. In addition to plant operation, maintenance visits were paid to non-attended plant; these included 1,637 visits to minor air-conditioning plant, 212 visits to refrigeration plant, 1,124 visits to water pumps and 506 visits to chlorination equipment. In addition 266 fault calls were attended.

City Hall

8.49 The City Hall Electrical and Mechanical Services Section main- tains all the electrical, mechanical and air-conditioning installations at the Hong Kong City Hall, carrying out the repair of faults, replace- ment of lamps of all types, installation of temporary wiring for flood and display lighting and operating the 700 TR air-conditioning plant as well as 21 zone cabinets. Operators were provided for the stage lighting of 1,082 performances and rehearsals, 328 cinema projections

and 47 slide projections. In addition to routine maintenance and annual overhauls of plant and equipment this section also undertook work involving modifications of the auditorium lighting electronic dimmer equipment and improvements to illumination in various areas of the City Hall. During the year the air-conditioning units installed in the Gavotte Restaurant were handed over to the Section for operation and maintenance.

Hong Kong International Airport

8.50 The Airport Electrical and Mechanical Services Section main- tains all the electrical, mechanical and air-conditioning systems as well as the runway and landing approach lights, substation equipment, air navigation beacons, baggage conveyor systems and passenger aerobridges at the airport. All plant and equipment was maintained throughout the year without major breakdown. As this Office's high pressure injecting testing apparatus is normally retained at the Airport this Section undertook the inspection and primary injection tests of 800-amp, 2,000-amp and 3,000-amp air circuit breakers for use in resettlement estates, low cost housing schemes and military establish- ments. In addition to normal routine maintenance and overhaul the re-routing of cables in connection with the laying of the new H.T. Ring Main system, the disconnection, removal and installation of lighting in connection with the improvements to the Airport and modification of the controls of passenger aerobridges was carried out.

Lion Rock Tunnel

8.51 The Lion Rock Tunnel Electrical and Mechanical Services Section operates and maintains all electrical and mechanical systems and electronic equipment connected with the toll booths and recorders, carbon monoxide monitoring equipment, visibility indication and alarm equipment, height detection equipment, emergency communication equipment, fire extinguisher alarm equipment, traffic aid signal control equipment, tunnel lighting, ventilation plants and 'no-break' generating sets as well as lane marker beacons at both ends of the toll plaza. Routine maintenance and overhaul of equipment continued through- out the year.

including steam boilers, calorifiers, sterilizers, steam heating and laundry equipment, emergency generators, hydrotherapy equipment and general lighting located in Government hospitals and in the British Military Hospital, as well as the Hung Hom pumping plant for the supply of sea water to the Queen Elizabeth and British Military Hospitals. The steam boilers and laundry equipment at Shau Kei Wan Medical Department Central Laundry were taken over for maintenance. During the year a total of 7,973 mechanical, 18,184 electrical and 1,125 air-conditioning repairs were carried out. 1,563 items of hospital equipment were overhauled.

MILITARY WORKS SUB-DIVISION

(Including the Royal Navy and Royal Air Force)

8.53 This Sub-Division is controlled by a small element at Head Office and the remainder is deployed in three Military Works Electrical and Mechanical Depots. These Depots are situated in the main military complexes with responsibility respectively for Hong Kong Island, Kowloon and New Territories. Each Depot is supervised by a Warrant Officer or Senior Non-Commissioned Officer of the Royal Engineers on secondment. The staff of each Depot numbers about 90 and they carry out inspections, minor repairs, planned maintenance tasks and attend fault calls. Within each Depot a small workshop with minor repair and test facilities exists to assist in the work. Major repairs and overhauls are carried out either in the main Electrical and Mechanical Workshops in Hong Kong or Kowloon or in situ by staff from these workshops. The maximum liaison between the Military Works Depots and the main Workshops is ensured by an experienced P.W.D. Inspector who plans and controls the flow of work. The Military Works Sub-Division provides a service for the Armed Forces which is essentially one of control and management involving electrical and mechanical equipment which varies from a simple domestic iron to a 1,500 KVA standby electricity generating station on Stonecutters Island.

8.54. During the year the staff of the Sub-Division have carried out 46,126 routine monthly inspections and routine servicing of plant, pressure vessels, air conditioners, kitchen equipment, refrigerators and miscellaneous items of equipment. A total of 40,166 repairs to all types of domestic equipment was carried out, 8,436 items of new

APPRENTICE TRAINING

8.55 At the end of the year there were 510 Apprentices under training in various Government Departments. This total includes 13 Apprentice Engineers, 114 Technical Apprentices and 383 Craft Apprentices. The figure of 544 expected in last year's report was not achieved due to resignations from the Scheme. Since its inception there have been 11% resignations in respect of Craft Apprentices and nearly 9% in respect of Technical Apprentices. Of the Craft Apprentice resignations approximately half were due to the fact that the individuals wished to continue full time academic studies.

8.56 of the old type apprentices undergoing training in the Water- works Office and this Office 16 completed their course during the year.

8.57 Four supernumerary posts of Workshop Instructor were approved during the year and staff recruited to fill them. These Officers will be placed in Departmental Workshops to relieve Workshop staff of the responsibility of training large numbers of Apprentices.

8.58 This year's Brown Cup winner is Mr. LEUNG Hip-hung of the Waterworks Office, who was adjudged to have made the best progress over the year in practical and theoretical fields.

Staff

STAFF, TRAINING AND WELFARE

8.59 With staff increases approved in the 1971-72 estimates and other additional posts created during the year, the establishment of the Office at the end of the year was 4,744. In addition to this, a sum of $200,000.00 was approved for the purpose of engaging casual labour as and when required.

8.60 Recruitment to the professional grades continued with two Assistant Electrical and Mechanical Engineers being recruited locally and one Electrical and Mechanical Engineer from overseas. Recruit- ment, however, has not been sufficient to maintain the professional grades at their full establishment.

GENERAL

9.01 The Highways Office is responsible for the planning, design, construction and maintenance of the public road system together with the associated sewerage and drainage works. It also concerns itself with traffic management schemes and all traffic and transport surveys which provide the basic data for the necessary traffic engineering planning and design. It is sub-divided into 8 divisions and 1 unit, the functions and responsibilities of which are outlined on the organization chart on page 117.

9.02 The majority of engineering works, including maintenance works, are carried out by contract. A direct labour force is maintained for minor road repairs and urgent drainage faults. Consulting engineers are engaged on a number of projects due mainly to staff shortage but in some instances consultants have been engaged for their specialist expertise.

9.03 Good progress was maintained on almost all engineering projects. The non-recurrent expenditure for the year amounted to $118,874,000 while $52,953,000 was spent on maintenance, minor improvements, storm damage repairs and works executed on private

account.

9.04 The office maintains a 24-hour skeleton organization through- out the year to deal with typhoon and rainstorm emergencies which may arise affecting public roads and drains and to provide assistance

9.06 The design, construction and maintenance of public roads and their associated sewerage and drainage systems are undertaken by these three works Divisions, who are responsible for works within their respective geographical areas.

9.07 The total number of major projects completed in the year numbered 65 with an aggregate value of $93 million and those in hand numbered 85 with an aggregate value of $341 million. Details and progress on some of these projects are described in paragraphs 9.14 to 9.26.

Maintenance

9.08 Heavy rains in May and June 1972 resulted in considerable additional burden on the Maintenance Sections of the Divisions. The exceptional rainstorm on 18th June, 1972 caused two catastrophic landslides, one in Sau Mau Ping, Kwun Tong and one in Po Shan Road on Hong Kong Island. Serious damage to the Colony's road network was also suffered through landslides and road collapses. A total of 537 incidents were reported. To cope urgently with the serious situation, staff and resources were diverted from other work to concentrate on emergency clearance and repair work. All but a few of the remedial works were completed by the end of the year. About $23 million was spent in repairing road damage and clearance of landslides caused by typhoons and rainstorms during the year.

9.09 In order to meet the growing need for maintenance of existing road and drainage systems the three Works Divisions were reorganized

122

Digitized by

Google

in October 1972 and a new Maintenance Section was established in each. This new arrangement proved successful and in response to the 'Keep Hong Kong Clean' Campaign, a major proportion of the staff effort was directed towards the repair of minor road defects, repainting and refurbishing of street furniture and the clearance of debris in conjunction with other departmental activities.

Utility Co-ordination

9.10 To minimize obstruction to vehicular and pedestrian traffic, close liaison was maintained with the utility companies, the Police and other Government Departments on the co-ordination of trench works. Monthly meetings continued to be held with their representatives to plan and phase such works. With the ever increasing demand for utility services, there was a corresponding rise in the number of road openings.

Works associated with Resettlement and Low Cost Housing Estates

9.11 Works on estate roads, drains and recreation areas continued at Ko Chiu Road and the Ho Man Tin Low Cost Housing Estates and at Lam Tin and Pak Tin Resettlement Estates. The contract for Stage VI roads and drainage works at the Sau Mau Ping Resettlement Estate was completed. Works continued on the provision of roads and drainage for Government Low Cost Housing Estates in Kwai Chung, 3 contracts being completed during the year.

Drainage and Sewerage Works

9.12 In conjunction with the various road construction pro- grammes, drainage works were carried out in a number of districts on Hong Kong Island including Wan Chai Reclamation, Causeway Bay, Chai Wan and the Peak. Construction of the large trunk sewer along the north side of Mei Foo Sun Tsuen progressed well. This sewer, when completed, will serve not only the adjacent area but also the new Princess Margaret Hospital at Lai Chi Kok.

NEW WORKS

9.13 The following paragraphs describe briefly progress on the more major work items. Details of projects completed or under con- struction are given in Appendices X and Y, while statistics relating to roads and drains are shown in Appendix AA.

Road Works in Hong Kong

9.14 The opening of two flyovers linking Upper Albert Road with Cotton Tree Drive and Kennedy Road this year marked the completion of another important stage of the Garden Road complex which was designed to improve traffic flow between Central District and the Mid-levels area.

9.15 Widening of Connaught Road, Central between Murray Road and Morrison Street was completed. Addition of new traffic lanes and installation of linked signals at road junctions contributed to a substantial improvement of traffic conditions in this busy road. A new road network on the reclamation fronting Connaught Road Central and a much expanded bus terminus were also constructed in con- junction with this scheme. A covered footbridge over Pedder Street at its junction with Connaught Road Central was completed while others in this area were being designed.

9.16 Pokfulam Road/Bonham Road/Hill Road junction was im- proved with the opening of the one-way flyover from Pokfulam Road to Bonham Road and the widening of the approaches to this heavily trafficked junction. A substantial length of Wongneichong Gap Road, leading to the south-east side of the island, was also improved and widened, incorporating an additional up-hill traffic lane.

9.17 The construction of two new roads, one linking Wongneichong Gap with Wong Chuk Hang and the other linking the Tin Hau Temple Road area with Tai Hang Road progressed satisfactorily. A number of minor new roads were also constructed in conjunction with building development in the Wan Chai Reclamation, Chai Wan, Jardines Lookout, Red Hill and Chung Hom Kok areas.

9.27 Design work on new highway structures included in the pro- gramme continued, and advice on structural matters was given to the Civil Engineering Office on request. Structural designs prepared by consulting engineers for highway projects continued to be checked, but this checking was mainly confined to designs prepared by newly- appointed consulting engineers.

Design Projects

9.28 The Division's main efforts were again expended on projects for Kowloon. Design for the elevated road between Prince Edward Road and Lai Chi Kok Road, and the grade-separated access to the Airport Maintenance Area were both completed, and considerable progress was made with the design for the West Kowloon Corridor elevated road joining Gascoigne Road to Tong Mi Road. Progress was also made with the design of the elevated highway between Kwun Tong and the Airport Tunnel Road.

9.29 Work for Hong Kong was largely confined to a feasibility study of the section of elevated road proposed on Pokfulam Road, which investigated the relative advantages of prestressed concrete, steel and reinforced concrete construction. Design work for two footbridges, one near Wah Yan College, and the other in North Point, was also started.

9.30 For the New Territories, Stage I of Tsuen Wan Bypass, running from Kwai Chung Road to Texaco Road in Tsuen Wan, has been the main project; uncertain foundation conditions have caused some design problems. Design work on three footbridges over Kwai Chung Road was completed.

Design Standards

9.31 Additions were made to the design standards manual as occasion demanded.

missioned for 8 additional projects and the expenditure on works undertaken by them was about $58 million.

9.33 Five firms of consultants (2 from overseas and 3 local) are currently engaged on over 30 projects. The road connections to the cross harbour tunnel were completed ready for its opening and work on a number of component contracts forming part of the Kowloon Foothills Road improvement scheme were started. Feasibility Studies of 3 major routes in the urban areas were carried out; these were the West Kowloon Corridor, the Airport Tunnel road and its western approaches, and the Aberdeen Tunnel and its approaches.

9.34 In the New Territories, the design of a new road between Tsuen Wan and Tuen Mun (Castle Peak), 94 miles long, was started. Work continued on Tsing Yi Bridge across Rambler Channel. This is being built by a private consortium and will be handed over to Government on completion. Consulting engineers undertook the con- struction of approach roads to the bridge on behalf of Government. Progress has been satisfactory.

9.35 As a result of the heavy rainstorms in May and June, the safety of a number of squatter and licensed areas gave cause for concern, and consultants were appointed to investigate and report on such areas.

9.36 A schedule showing projects undertaken by Consulting engineers is at Appendix Z.

9.38 Increase in vehicle registration continued to be high. The actual number of vehicles registered rose by 23,966 to 193,434, representing a rate of increase of 14.1%. The trend in vehicle increase over the last few years has resulted in more wide spread traffic con- gestion within the urban areas and an acute shortage of parking space throughout the Colony.

9.39 The graph on page 121 illustrates the growth in population, road mileage, accidents involving injury and vehicle registration in the past decade. It may be seen that the vehicle registration total is expected soon to exceed 200,000 units and that there are over 300 vehicles for every mile of road.

Traffic Aids

9.40 Routine installations of all types of traffic aids continued throughout the year in conjunction with highway improvement schemes or as separate items.

9.41 As in previous years the Stanley Prison Sign Shop continued to manufacture reflectorized traffic signs. With the recent purchase of a stoving oven it is hoped to train staff in the production of stoved enamel signs, thus increasing the capacity and range of products supplied by the Sign Shop. To supplement the production of the Sign Shop a contract for stoved enamel signs was entered into with a local manufacturer. Contracts were also let during the course of the year for the supply of rubber traffic cones and traffic sign supports.

9.42 A policy on Directional Signs giving guidance on siting, layout, letter sizes etc. was prepared and issued. Directional signs, designed to conform with this policy, were provided for the guidance of traffic on the Cross Harbour Tunnel Road Connections (Island and Mainland ends), Garden Road Complex Stage IV, New Central Bus Terminus, Marsh Road Flyover, Pokfulam Road/Bonham Road Flyover, Kow- loon City Interchange, San Po Kong Interchange, and Kwun Tong and Tai Kok Tsui Ferry Terminals. These involved the erection of many gantry structures spanning carriageways.

9.43 Ten illuminated traffic aids on the Island were installed, whilst 8 were removed. A total of 171 illuminated traffic aids were installed and 120 removed in Kowloon. In the New Territories the corresponding figures were 58 and 8.

Parking

9.44 In the Central District of Hong Kong Island, the construction of a multi-storey car park capable of parking 900 vehicles was nearing completion. A temporary off-street car park for over 500 vehicles at the Ex-Naval Dockyard was constructed and put into operation. In the private sector the provision of a multi-storey car park for 800 vehicles at the Plaza Hotel, Causeway Bay was in an advanced stage of construction.

9.45 The installation of parking meters continued. There were net increases of 39 metered spaces on Hong Kong Island and 963 in Kowloon.

9.46 A scheme was launched for the extension of the time of operation of metered parking in certain areas from 7.00 p.m. up to midnight. Work under this scheme has been completed in the Wan Chai, Happy Valley and Causeway Bay areas on the Island. On the Mainland a similar extension of the time of meter operation was made to parking spaces in the Yau Ma Tei and Mong Kok areas.

9.47 To cope with the increase of commercial vehicles, 241 lorry loading/unloading spaces at the Western District of the Island were designated. There was a net increase of 106 lorry loading/unloading spaces in Kowloon and 53 in the New Territories.

9.48 There was a net decrease of 41 designated parking spaces for motor cycles on the Island. On the Mainland the provision of such parking spaces increased by 152 in Kowloon and by 24 in the New Territories.

Traffic Light Signals

9.49 Four additional sets of traffic light signals were installed on the Island. The total number of sets in operation on Hong Kong Island is now 89.

9.50 On the Island, the designs for a further 18 signal intersections were completed and the installation of 5 sets of light signals was in hand.

9.51 On the Mainland, a total of 9 additional sets of traffic light signals were installed at intersections and crossing places. The total number of installations now in operation is 149.

9.52 The designs of a further 5 installations on the Mainland were completed, and the installation of a further 16 sets in Kowloon and 1 set in the New Territories was in progress.

9.53 The replacement of 100 sets of existing pedestrian signals with 'Walking Man' lenses at Central and Wan Chai Districts of the Island was completed.

9.54 The phasing and timing of existing signal installations were reviewed and adjustments were made where changes of traffic pattern had been observed.

Street Lighting

9.55 A total of 205 new street lamps were installed on the Island, 519 in Kowloon and 396 in the New Territories.

9.56 Annual expenditure on street lighting increased by 6.2% from $1,897,000 to $2,015,000 on Hong Kong Island.

9.57 On the Mainland, the annual expenditure on street lighting increased by 6.1% from $4,279,000 to $4,542,000, expenditure being $3,280,000 in Kowloon and $1,262,000 in the New Territories.

Public Transport

9.58 The planning, design and improvement of bus stops, bays, termini, public light bus stands and other facilities continued through- out the year, either independently or as part of road improvement schemes.

9.59 The new Central Bus Terminus on Central Reclamation of the Island, replacing the existing one at the Vehicular Ferry Concourse, was completed and put into use.

9.60 In connection with a comprehensive traffic management scheme for the Central District on the Island, four on-street and three off-street Public Light Bus Termini were planned. All major traffic routes in the area will be made clearways or prohibited to Public Light Buses in order to improve the traffic flow.

9.61 Work on the duplication of the taxi rank at the Star Ferry Concourse on the Mainland was completed.

9.62 A public light bus terminus at Ferry Street in Kowloon was completed and put into use in mid-April.

9.63 Facilities for taxis, public light bus termini and franchised bus termini were put in operation with the opening of the two new ferry concourses at Kwun Tong and Tai Kok Tsui, Kowloon.

9.64 There was a net increase of 2 public light bus stands on the Mainland and a number of major traffic routes were declared clearways for public light buses in order to improve traffic flow.

9.65 Expansion of bus services on both the Island and the Main- land continued. Four cross harbour bus routes have been introduced since the opening of the Cross Harbour Tunnel.

Pedestrian Facilities

9.66 The first part of the elevated walkway system in the Central District, that along Pedder Street extension, was completed and opened to the public. This facility gives complete segragation of pedestrians from vehicular traffic at the busy road junction of Pedder Street and Connaught Road Central. Planning and design for the remaining foot- bridge and elevated walkway network were well advanced and sections are ready for implementation in the near future.

9.67 On the Island six footbridges at the Waterfront Road / Cross Harbour Tunnel Interchange were completed. On the Mainland two footbridges were completed, one at Princess Margaret Road and another at Choi Hung Road.

9.68 Modification of existing traffic light settings to facilitate pedestrian movement at intersections was also carried out at many locations.

Investigation

9.69 On Hong Kong Island 60 traffic counts and 13 minor traffic studies were carried out in conjunction with traffic management schemes and the planning of new road layouts, while 88 traffic counts of a similar nature were conducted on the Mainland.

9.70 Following the results of a speed survey conducted by the Traffic and Transport Survey Division, the speed limit along the whole length of the Waterfront Road was raised to 40 m.p.h.

Planning and Design

9.71 The examination of Town Planning Layouts prepared by the Planning Branch of Crown Land and Survey Office continued

(Acting)

Government Mass Transit Engineer:

S. A. BARDEN, B.Sc. (Eng.) (Hons.), C.Eng., M.I.C.E., M.I.T.E.

10.01 The Mass Transit Department is responsible for all matters concerning the Mass Transit Railway system. Its primary function is to examine and evaluate the work of the Consulting Engineers and to direct their activities after ensuring that all aspects of this project are based on sound engineering concepts and are entirely appropriate for the circumstances. In addition, the department is responsible for co-ordinating all Government activities and public works associated with the Mass Transit Railway project and for examining all public and private development affected by the scheme to ensure that there is no conflict with the Mass Transit programme. The department is also responsible for co-ordination and liaison duties in respect of the Cross Harbour Tunnel project, the Tunnel Road Connections and other ancillary schemes linked to the Cross Harbour Tunnel.

10.02 The department has a total establishment of 37 in 16 different grades.

10.03 In June Government approved in principle the Mass Transit Railway system subject to satisfactory financial, contractual and opera- tional arrangements being made. Thereafter, international invitations were issued to all interested parties to submit proposals for financing, constructing and/or operating the railway, as a result of which Government decided, in February, to proceed immediately with the first four stages of the project subject to a decision on whether con- struction was to be carried out under single contract or under a series of separate contracts. Government also announced that the operation of the Mass Transit Railway would be entrusted to a public corporation to be established under a special ordinance.

Investigations and Design

10.04 In July 1972 the Consulting Engineers, Messrs. Freeman Fox & Partners (Far East) were re-appointed to investigate fully the sub-soil conditions, arrange for accurate surveys to be carried out and prepare

137

the final detailed design and contract documents for the first four stages in accordance with an agreed programme. Good progress was maintained on the soils investigations with 150 boreholes completed and contract documents finalized for a further 900 boreholes. Contract documents for four trial tunnels, to be undertaken at Tsim Sha Tsui, Admiralty (the former Naval Dockyard area), Lok Fu and Lai Chi Kok were also prepared. Field work for the large scale survey plans to a metric scale was completed.

10.05 The design of the track alignment, station layouts, rolling stock, train control, telecommunications and power supply and Kowloon Bay Maintenance Depot proceeded broadly in accordance with the agreed programme. The track layout at Mong Kok was revised and two stations, Prince Edward and Argyle, were substituted for Mong Kok Station. The layout of Admiralty Station was amended in conjunction with alterations to the track layout west of the station. A revised design of the ventilation/air conditioning system was commenced.

Co-ordination and Planning

10.06 Throughout the year, all public and private development proposals along the railway routes were examined to ensure that they did not conflict with the construction of the project. A total of 65 private redevelopment proposals were examined and, in nearly all cases, it was possible to preserve the Mass Transit routes by recom- mending either a suitable redesign of foundations or amendments to the redevelopment plans. In one case, it was recommended that the property be acquired.

10.07 The land required for the construction of the first four stages of the railway was identified and preliminary consideration was given to its acquisition. A Land Acquisition Co-ordinating Committee was formed to resolve the numerous problems that will arise out of obtaining possession of the land required for the construction of the railway. A total of 71 sites have so far been considered by the Committee. The drafting of legislation for the acquisition of land for the project was well advanced.

10.08 A series of meetings was held with representatives of the utility companies and the Consulting Engineers to examine the effect of the construction of the railway on the various utility services and

138

to find the most satisfactory method of organizing their diversion. A Utilities Co-ordinating Group was recommended and, pending its establishment, individual members commenced an assessment of the work required at individual station sites.

10.09 Considerable liaison took place with other Government Departments and P.W.D. Offices to co-ordinate items in the Public Works Programme which are associated with or affected by the construction of the Mass Transit Railway.

10.10 Heavy demands were made on the time of senior staff for attendance on committees and discussions with Government Depart- ments and representatives of local and overseas firms interested in the project. In particular, the Mass Transit Department participated in fifteen committees through which the various aspects of the project were planned, co-ordinated and controlled.

GENERAL

11.01 The Waterworks Office is responsible for all aspects of water supply and distribution carried out by Government. The work is divided among seven divisions and three units each with specific responsibilities as shown on the operation and organization chart. Consulting engineers are appointed to carry out planning, feasibility studies and construction of new works which require specialist knowledge or at times when the resources of the Office are fully extended. A list of projects undertaken by consultants is given at Appendix BB. New works and a large proportion of the maintenance work are carried out by contract but the operation of supply, the distribution of water and maintenance of meters and machinery is done by Waterworks staff.

Mains Sub-Division

11.08 Extensions to both fresh and salt water distribution mains were carried out to supply new development areas, undersized or defective mains replaced, and alterations made to facilitate road construction work. A total of 66 miles of mains were laid as exten- sions to the fresh and salt water distribution systems. Details of mains laid are given in Appendix CC under item (9).

11.09 Systematic waste detection continued throughout the year. Quarterly checks were carried out in 294 fresh water areas and annual checks in 65 salt water areas. A number of major leaks were discovered and repaired, resulting in an estimated daily saving of more than four million gallons of water.

House Service Sub-Division

11.10 The number of additional meters installed was 70,042. This was an increase of 18% on the number installed during 1971-72 and brought the total number of meters in service to 554,089.

11.11 The Division comprises a Headworks Sub-Division, respon- sible for the maintenance and operation of storage reservoirs, intakes, filter stations, trunk mains and service reservoirs, and an Operation Sub-Division, responsible for monitoring pumping stations, treatment works, service reservoirs and other facilities, for the collection and processing of hydrological data for design and record purposes, and for the development of rules for the operation of the multi-reservoir system.

11.12 At the end of the year 29,508 million gallons of water were held in storage, including 21,020 million gallons in the Plover Cove Reservoir. Storage at the end of the previous year was 25,861 million gallons, of which 18,238 million gallons was in Plover Cove. Rainfall for the year was 111.41 inches, which is 30.4% above average, and the total yield from the catchments was 47.6% higher than last year.

A total of 18,604 million gallons of water was received from China during the year. This includes the supply of an additional 3,000 million gallons following an agreement reached with the People's Council of Kwangtung Province in January 1972.

11.13 In mid November 1972, as a result of discussion with the Chinese Authorities during the visit, to Kwangtung, of a delegation of Waterworks senior officers led by the Director of Public Works, agreement was reached to supply the Colony with an additional 3,500 million gallons per annum on a continuing basis, making a total supply of 18,500 million gallons per annum. It was also agreed that, with immediate effect, the supply period should be from 1st October to 10th August each year (previously 1st October to 30th June).

11.14 All the Colony's reservoirs with the exception of Plover Cove filled as a result of the heavy rainstorms in summer. Had the reten- tion level of Plover Cove not been increased as a result of progress on the dam raising works it would have been full at the end of the wet season. The higher retention level increased storage capacity from 36,742 million gallons to 41,689 million gallons.

11.15 The 24-hour supply continued throughout the year. The average daily consumption was 201.6 million gallons with a peak demand of 234.9 million gallons. These figures are respectively 10.1% and 9.3% higher than the corresponding figures for 1971-72.

Headworks Sub-Division

11.16 The maintenance of a balanced draw-off between the reservoirs was difficult due to shut-downs at Tai Po Tau pumping station in connection with the Plover Cove extension works. Draw- off from Plover Cove reservoir was stopped in April 1972 and March 1973. The former shut-down was required for the removal of temporary bulk-heads installed in October 1971 in the tunnel linking the reservoir to Tai Po Tau. During the March shut-down, tunnel gates were installed at the portals at each end of the tunnel and at the junction of the tunnel and the Tau Pass culvert. During this stoppage advantage was taken to desilt the tunnel and branch tunnels. During the shut-downs a fully treated supply was maintained with draw-offs from old reservoirs as well as water from China.

11.17 Weekend patrol of catchment areas by Waterworks staff continued on a regular basis to minimize abuse by visitors which might lead to pollution and to discourage indiscriminate disposal of litter.

11.18 The routine maintenance of access roads, catchwaters, control gates, treatment works, pumping stations, staff quarters and depots, and the maintenance and cleaning of service reservoirs continued.

11.19 Two heavy rainstorms, in May and June, caused widespread damage to Waterworks installations, the estimated cost of repairs being $3.5 million. Of this, damage estimated at $1 million to headworks installations occurred in May, whereas the more severe rainstorm in June caused to the value of $2.5 million. Damage to installations resulted in the interruption of supplies to Stanley for almost a day and the island of Cheung Chau was on restricted supply for three days whilst repairs were carried out.

Operations Sub-Division

11.20 The Government I.C.L. 1903A series computer is used in connection with reservoir system operations, the determination of consumption statistics and other supply criteria. During the year, a computer programme for the determination of reservoir draw-off rates was introduced and work was completed on the development of reservoir regulation rules. The 1971 trade consumption figures were analysed on the basis of supply zones and the nature of the trades. Work continued on the per-capita consumption study and a review of pumping station capacity throughout the system was completed. A number of routine reports were prepared including a comprehensive report on reservoir yields and consumption in major supply zones over the period 1969 to 1972.

Hydrological Section

11.21 Routine maintenance of 123 rain gauging stations, 23 stream and reservoir gauging stations and one evaporation station continued. In connection with the High Island Water Scheme, weekly readings of water levels at 19 observation wells and 13 low flow weirs also continued.

11.22 Data abstraction and preparation of Volume VII in the series of 'Hong Kong Rainfall and Run-off' and the preparation work for printing a revision of 'Gross Yield of Hong Kong Reservoirs' continued. A study employing the aid of a computer is also being made on the gross yields and pumpable yields of the River Indus flood pumping scheme.

WATER QUALITY CONTROL UNIT

Senior Waterworks Chemist:

D. L. MAKER, A.R.I.C., P.A.I.W.E.

11.72 This Unit is responsible for controlling water treatment at filter stations and for maintaining a satisfactory quality of supply throughout the distribution system. It operates two main and two subsidiary laboratories for testing water samples and miscellaneous materials connected with the water supply industry.

11.73 The Unit also carries out investigations into improved or more economical methods of water treatment and deals with various problems arising in connection with water quality. Its analytical and advisory services are utilized in the planning and commissioning of new supply projects and by other government departments, commercial and industrial firms, and the general public.

11.74 The total number of samples examined increased by 14% to 38,659, of which 64% were for chemical testing, while 20% and 16% were for bacteriological and biological examination respectively. Other government departments, etc. submitted 1,148 samples, a 4% increase. In addition, a large number of analyses were carried out on stream samples in connection with the 'North Western Water Scheme Pollution Study' on behalf of the consultants engaged on the study.

Water Treatment

11.75 In general treatment at waterworks comprises coagulation with alum and lime followed by rapid gravity filtration, sterilization using chlorine, pH value correction and fluoridation. At stations designed to treat water from the more polluted sources filtration is preceded by sedimentation and chlorination. At Sha Tin treatment works activated carbon for control of taste and odour and poly- electrolytes to assist the clarification and filtration processes can also be dosed as and when required.

11.76 At Sha Tin and certain other stations the replacement of part of the sand in the filters by a layer of graded crushed anthracite successfully increased filtration rates and a report on performance was prepared.

11.77 Consumption of principal chemicals used in treatment was as follows:

Quality of Supply

11.78 The purity of treated water achieved, both chemically and bacteriologically, continued to be considerably higher than target standards recommended by the World Health Organization.

11.79 Generally the supply is classified as soft, and low to moderate in salt content. The chemical quality in most areas is subject to some fluctuation according to the proportion of water abstracted from Plover Cove reservoir which has a higher mineral content than water from other sources. Principal characteristics given in parts per million (p.p.m.) were as follows:

11.80 Fluoridation of supplies, started in 1971 to reduce dental decay in children, continued. The average level achieved during the year was 0.8 p.p.m. fluoride against a nominal target of 1.0 p.p.m.

11.81 The standard of bacteriological quality aimed at throughout the distribution system is absence of coliform organisms in 100 millilitres of sample. All 2,817 samples taken regularly from service reservoirs conformed to this standard as did all 2,085 random samples taken from taps connected directly to water mains. Of 1,167 samples from taps fed via private storage tanks 97.9% were free from coliform organisms.

Plover Cove

11.82 Regular chemical, limnological and biological surveys con- tinued in Plover Cove Reservoir where summer inflows reduced the salinity from 260 p.p.m. (NaCl) in May to 150 p.p.m. by November, the total of all dissolved salts being then 220 p.p.m. The general quality of the stored water remained good but an unusual earthy-musty taste and odour persisted for about 3 weeks during November when dosing of powdered activated carbon before filtration was necessary at Sha Tin treatment works, to maintain palatability. There was no further fish stocking but a research student from Hong Kong University began a study of the naturally occurring species of Tilapia which is thought likely to assume the functions of biological control hitherto performed by the stocked species of carp.

11.93 Close liaison was maintained with the consultants' office and site staff and regular site visits were made to monitor progress and claims and to ensure that site records were satisfactory. The great proportion of the time was devoted to the Plover Cove, High Island and 40 million gallons per day desalter projects.

11.94 The Unit is responsible for examining Standard Forms, Conditions of Contract and other standard procedures and drafted two documents, 'Conditions of Contract for Maintenance Works in Civil Engineering, Highways and Waterworks Office and 'Sub-contract Conditions', for use in conjunction with the General Conditions of Contract for Civil Engineering Construction within the Public Works Department.

APPRECIATION

12.01 It is unusual for a year to pass without the P.W.D. being involved in one sort of crisis or another but 1972 was catastrophic. The rainstorms of June were the most severe ever recorded, as were the associated landslides, damage to property and loss of life. As is usual in these circumstances, all branches of the Department, whether directly involved or not, turned to and gave a helping hand but with widespread damage of this nature the brunt of work once again fell upon the Highways Office and Buildings Ordinance Office--and once again they responded magnificently.

12.02 These offices were manned on a 24-hour basis at the onset of the heavy rains and hence ready and mobilized for emergency work from the moment their services were needed. But the emergency escalated so rapidly that soon the full staff of both offices were deployed on a 24-hour emergency basis. This continued for many weeks to the detriment of the normal routine of the offices and the resulting backlog of work in the Buildings Ordinance Office persisted throughout the year, putting further strain on a short-staffed and overworked office.

12.03 Other offices may not have been beset with problems and strains both mental and physical-as severe as those which descended on the Buildings Ordinance and Highways Offices but staff shortages have resulted in every office, branch, division and section of the P.W.D. being overworked. This has now persisted for a number of years and as this is my last report as Director of Public Works I wish to record my admiration of the spirit and dedication with which the staff at all levels have tackled their respective duties. I thank them for the support and co-operation they have given me not only as D.P.W. but over the 27 years I have been with the Department.
