Members are invited to recommend to Finance Committee the upgrading of 214ES, 215ES, 216ES and 220ES to Category A at an estimated total cost of $337.2 million in money-of-the-day prices for the construction of four secondary schools in the territory.
PROBLEM
The Director of Education (D of E) forecasts that there will be a shortfall of 501 secondary school classes in the territory by the year 1999.
PROPOSAL
2. The Director of Architectural Services (D Arch S), with the support of the Secretary for Education and Manpower, proposes to upgrade the following projects to Category A at an estimated total cost of $337.2 million in money-of-the-day (MOD) prices -
| | Project Estimate

PROJECT SCOPE AND NATURE
3. The proposed schools are standard design school buildings. Each school will have -
- 26 classrooms;
- 14 special rooms;
- three remedial teaching rooms;
- a guidance activity/interview room;
- two interview rooms;
- a staff common room;
- a student activity centre;
- an assembly hall; and
- ancillary facilities.
JUSTIFICATION
4. D of E forecasts that there will be a shortfall 501 secondary school classes in the territory by the year 1999. Upon completion of 211ES "Secondary school in area 31, Tin Shui Wai", 202ES "Third secondary school in area 56, Tseung Kwan O", 209ES "Two secondary schools in area 56, Tseung Kwan O", 213ES "Secondary school in area 20, Fanling", 217ES "Secondary school in area 17, Tung Chung", 218ES "Secondary school in Chai Wan Estate" and 219ES "Secondary school in area 14B, Shatin" [1) Projects 211ES , 202ES , 209ES and 213ES are now in Category A of the Public Works Programme. PWSC recommended the upgrading of 217ES , 218ES and 219ES to Category A at its meeting on 21 May 1997. Finance Committee will consider the recommendations at its meeting on 13 June 1997.] 1) in the year 1999, we will increase the provision of secondary school classes in the territory by 208 classes, resulting in a shortfall of 293 classes.
5. In order to reduce the projected shortfall of secondary school classes as well as to reduce the size of secondary school classes and to phase out floating classes in Secondary One to Secondary Five in accordance with the Government policy, we propose to construct four secondary schools in the territory. We are planning to construct more schools in the territory to meet the remaining shortfall.
FINANCIAL IMPLICATIONS
6. We estimate the capital costs of 214ES, 215ES, 216ES and 220ES to be $83.0 million, $72.6 million, $103.0 million and $78.6 million respectively in MOD prices (see paragraphs 7 & 8 below), made up as follows -

9. We have derived the MOD estimates on the basis of the Governments forecast of trend labour and construction prices for the period 1997 to 2001. We will tender the works under fixed-price lump sum contracts because we can clearly define the scope of works in advance, leaving little room for uncertainty.
10. We estimate the annually recurrent expenditure for each school to be $33.4 million. As the new schools will be operated as aided schools, the individual sponsoring body will bear the costs of furniture and equipment, estimated at $6.1 million for each school.
PUBLIC CONSULTATION
11. We consulted the Social Services Committee of the Tuen Mun District Board on 214ES and the Community Building Committee of the Eastern District Board on 216ES in April 1997. We also consulted the Tai Po District Board on 215ES and the Social Services and Publicity Committee of the Yuen Long District Board on 220ES in May 1997. They all supported the respective projects.
ENVIRONMENTAL IMPLICATIONS
12. The Director of Environmental Protection (DEP) vetted the Preliminary Environmental Reviews (PERs) completed by consultants of D Arch S on 214ES, 215ES and 216ES in December 1996. The PERs have concluded that with the provision of relevant mitigation measures, the impact of road traffic noise on the three proposed schools can be reduced to within the criteria stipulated in the Hong Kong Planning Standards and Guidelines. We have included in the project estimates the costs to implement the following environmental mitigation measures -

(b) the school building will be set back 25 metres from the adjacent Light Rail Transit line.

|

|---|
|
(b) provision of openable Type II well-gasketted windows [3) Type II windows provide additional noise insulation through the use of well-gasketted windows and 8-millimetre thick glass pane.] 3) and air-conditioning to three teaching rooms on the southwest facade of the special room block; and
|
|
|
(c) provision of fixed windows to nine teaching rooms on the northwest facade of the classroom block.
|
|
13. For 220ES, the consultants of the Director of Territory Development (DTD) completed an Environmental Impact Assessment (EIA) study in March 1997 to assess the environmental impacts arising from the Tin Shui Wai Further Development. The Advisory Council on the Environment endorsed the findings of the EIA Study at its meeting on 21 April 1997. The Study has concluded that with the provision of relevant mitigation measures, the impact of road traffic noise to the proposed school can be reduced to within the criteria stipulated in the Hong Kong Planning Standards and Guidelines. DTD has included in the relevant engineering contract the cost to implement the following mitigation measures -
- construction of 4 to 4.5-metre high road side noise barriers along Ping Ha Road; and
- provision of temporary noise mitigation measures prior to the completion of the noise barriers.
14. We will control noise, dust and site run-off nuisances during construction through the implementation of mitigation measures in the relevant works contracts to comply with the established guidelines/standards.
LAND ACQUISITION
15. The four projects do not require land acquisition.
BACKGROUND INFORMATION
16. We upgraded 214ES, 215ES, 216ES and 220ES to Category B in April 1997.
17. We have completed site investigations and are finalising the working drawings and tender documents for the four projects using in-house staff resources. We plan to start the construction works for the four projects in January 1998 for completion in August 1999.

*Assumptions 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 130 nos. of steel H-piles of an average depth of 30 metres.
- 3. Provision for the site safety of 2% of the estimated contract sum (which does not attract contingencies) is included in the building cost.
- 4. Cost for drainage and external works is for a standard school site area of 6 950 square metres built on a flat site. No diversion of existing utilities or noise mitigation measures are required.
- 5. No consultancy services are required.
- 6. Furniture and equipment cost is excluded as it is usually borne by the sponsoring body.
Notes
- The piling costs for the following proposed projects are higher as they are adjusted to suit individual site conditions -
|
Project
|
Piles
|
|---|
|
214ES
|
140 nos. of steel H-piles of an average depth of 40 metres. |
|---|
|
216ES
|
22 nos. of 2-metre and 8 nos. of 2.5-metre large diameter bored piles of average depth of 50 metres. |
|---|
|
220ES
|
120 nos. of steel H-piles of average depth of 35 metres. |
|---|
- For 214ES, 215ES and 216ES, the building costs are higher due to the provision of insulated windows as a noise mitigation measure.
- For 214ES, 215ES and 216ES, the building services cost are higher due to the provision of air-conditioning as a noise mitigation measure.
- For 215ES, the drainage and external works cost is higher due to a larger than standard site area of 9 460 square metres.
For 220ES, the drainage and external works cost is higher because $0.5 million is required for the relocation of the existing lamp posts.
