PROBLEM

The Director of Education (D of E) forecasts that by 1998, there will be a shortfall of 46 primary school classes in school zone 219 (Lam Tin and Lei Yue Mun).

PROPOSAL

2. The Director of Architectural Services, with the support of the Secretary for Education and Manpower, proposes to upgrade 192EP to Category A at an estimated cost of $62.8 million in money-of-the-day (MOD) prices for the construction of a primary school in Ko Chiu Road, Kwun Tong.

PROJECT SCOPE AND NATURE

3. The proposed school will be of a new standard design. It will comprise -

1. 30 classrooms;
2. four special rooms;
3. three remedial teaching rooms;
4. a guidance activity/interview room;
5. two interview rooms;
6. a staff common room;
7. a student activity centre;
8. a library; and
9. an assembly hall and ancillary facilities.

JUSTIFICATION

4. For school zone 219 (Lam Tin and Lei Yu Mun), there are at present five primary schools providing a total of 174 classes. We will provide three additional whole-day primary schools in 1996. However, due to the Housing Authority's comprehensive Redevelopment Programme, we will close down three primary schools, two in 1996 and one in 1998, resulting in a net decrease of 30 classes. D of E forecasts that the demand for primary school classes in this school zone will reach 190 classes in 1998. There will be a shortfall of 46 classes. In order to alleviate the shortfall, we will require a new whole-day primary school by 1998. We will absorb the remaining shortfall of 16 classes in adjacent school zones where there is surplus provision.

FINANCIAL IMPLICATIONS

5. We estimate the capital cost of the project to be $62.8 million in MOD prices (see paragraph 6 below), made up as follows -

6. Subject to approval, we will phase expenditure as follows -

7. A comparision between the standard cost of building a primary school and the cost of this project is at Enclosure II. We derive the MOD estimate on the basis of the Government's forecasts of trend labour and construction prices over the period between 1995 and 2000. We will separate the site formation and piling works from the superstructural works by two contracts because the former will include drainage diversion works which require specialized expertise. The two contracts will be fixed-price lump-sum contracts because we can define clearly the scope of works in advance, leaving little room for uncertainty.

8. Owing to site constraints, we need to divert the existing drainage nullah and water mains which are at present running across the site. The Director of Water Supplies (DWS) will undertake the watermain diversion works. We will include the drainage diversion works in the site formation and piling contract.

9. We estimate the annually recurrent expenditure for the school to be $13.6 million. As the new school will be an aided school, the sponsoring body will bear the costs of furniture and equipment, estimated at $1.9 million.

PUBLIC CONSULTATION

10. We consulted the Kwun Tong District Board in November 1995. The District Board supported this project.

ENVIRONMENTAL IMPLICATIONS

11. Consultants engaged by the Architectural Services Department completed a Preliminary Environmental Review on this project in March 1995. Because of the location and small scale of this project, they envisaged that there was limited potential for adverse impacts on the environment associated with the operation of the school. An Environmental Impact Assessment was therefore not necessary. For short term impacts, we will control the construction noise, dust and site run-off to within established standards and guidelines through the implementation of appropriate mitigation measures in relevant contracts.

LAND ACQUISITION

12. This project does not require land acquisition.

BACKGROUND INFORMATION

13. We included 192EP in Category B in September 1995.

14. We have engaged consultants to carry out structural engineering design, structural engineering documentation and quantity surveying documentation for the pre-construction stage of the project at an estimated cost of $1.05 million, which is charged to the block allocation Subhead 3009GX "Consultants' fees for building projects". We will complete the detailed design for this project in early December 1995.

15. DWS will start watermain diversion works in February 1996 for completion in November 1996. We will then proceed with the site formation and piling works in December 1996 and superstructural works in May 1997 and complete the whole project in July 1998.

Enclosure I

192EP - Primary school in Ko Chiu Road, Kwun Tong

Breakdown of the estimate for consultants' fees

Notes

1. The average estimated cost per professional man month is about equivalent to a professional on MPS point 44.
2. The average estimated cost per technical man month is about equivalent to a Technical Officer on MPS point 20.
3. The figures given above are based on estimates prepared by the Director of Architectural Services. We will only know the actual man months and actual fees when we have selected the consultants through the usual competitive system.
4. The estimated consultants' fees represent 2.5% of the total project estimate, and cover post contract site supervision services and contract administration services for quantity surveying discipline and structural engineering discipline.

Enclosure II

* Assumption for standard cost

1. No site formation work/geotechnical work is required as it is normally carried out under a separate engineering vote.
2. Piling cost is based on 110 nos. of steel H-piles of an average depth of 30 metres.
3. Cost for drainage and external works is for a standard school site area of 6 200 square metres.
4. No diversion of existing utilities is required.
5. No noise mitigation measures are required.
6. No consultancy services is required.
7. F&E cost is excluded as it is usually borne by the sponsoring body.

Notes

1. Includes construction of retaining walls to retain the cutting of existing hillslope and forming the slightly sloping site to level.
2. Based on 90 nos. of steel H-piles of an average depth of 20 metres.
3. Includes diversion of an existing watermain and drainage nullah.
4. Consultancy services for quantity surveying and structural engineering discipline are required.
