PROBLEM

There are no grade-separated pedestrian crossings to serve the recreational facilities in area 3, Tsing Yi.

PROPOSAL

2. The Director of Territory Development, with the support of the Secretary for Planning, Environment and Lands, proposes to upgrade part of 175CL to Category A at an estimated cost of $78 million in money-of-the-day (MOD) prices for the construction of three footbridges, a staircase and a ramp, in area 3, Tsing Yi.

PROJECT SCOPE AND NATURE

3. The scope of 175CL comprises the construction of -

1. roads and drains in area 16, Tsing Yi; footbridges across Roads TY4 (Tsing King Road) and TY6 (Tsing Luk Street) in area 3, Tsing Yi;
2. minor roads and slope improvement works near the entrance to Peninsula Electric Power Company; and
3. North Tsing Yi boatyard rehabilitation works.

4. We now propose to upgrade the works described in paragraph 3(b) above to Category A. This comprises the construction of -

1. footbridges A and B across Tsing King Road;
2. footbridge C across Tsing Luk Street;
3. a staircase and a ramp between Tsing Yi Garden and Tsing Yi Town Clinic; and
4. associated drainage, landscaping and ancillary works.

JUSTIFICATION

5. The recreational facilities in Tsing Yi area 3 comprise the recently completed Tsing Yi Park and Tsing Yi swimming pool, and the Regional Council Complex and the Tsing Yi sports ground which will be completed by end 1998. These recreational facilities Tsing Luk Street and will serve a population of 140 000 in Tsing Yi.

6. Tsing King Road is a straight main thoroughfare. Tsing Luk Street links up Tsing Yi Estate and Tsing King Road. These roads separate the various recreational facilities from each other as well as from the residents. the recreational facilities in area 3 and to enhance pedestrian safety, wWe need to provide grade-separated crossings above these roads linking the nearby residential areas with the recreational facilities so as to ensure safe pedestrian access and to maximise usage of the facilities.

7. The proposed footbridge A will connect Tsing Yi Park with the existing elevated covered walkway at Tivoli Garden. This will provide a safe grade-separated crossing above Tsing King Road linking Tsing Yi Park with the Tsing Yi Swimming Pool and Sports Complex.

8. The proposed footbridge B will connect the existing elevated covered walkway at Serene Garden and the passageway at the Regional Council Complex. This will provide another safe grade-separated crossing over Tsing King Road to facilitate residents to make use of the Regional Council facilities.

9. The proposed footbridge C will provide safe access for residents at Tsing Yi Garden to the Regional Council Complex by means of a grade-separated crossing over Tsing Luk Street.

10. We also propose to construct a staircase and a ramp between Tsing Yi Garden and Tsing Yi Town Clinic to provide a direct access between the Tsing Yi Town Clinic and Tsing Yi Garden and Tsing Yi Estate via the proposed footbridge C and the existing elevated walkway between these residential areas.

11. To match the expected pedestrian flow, we have designed footbridges A, B and C to have a capacity of 7 000, 7 000 and 4 000 pedestrians per hour respectively in both directions.

FINANCIAL IMPLICATIONS

12. We estimate the capital cost of the project to be $78 million in MOD prices (see paragraph 13 below), made up as follows -

We propose to employ site staff through consultants as we do not have sufficient in-house staff to supervise the project. A breakdown by man months of the estimate for consultants’ fees for construction stage and resident site staff costs is at the Enclosure.

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

14. We have derived the MOD estimate on the basis of the Government’s forecast of trend labour and construction prices for the period 1997 to 2000. We will tender the works under a fixed-price lump sum contract because we have firm quantities for the majority of the works. As the contract period is less than 21 months, the contract will not provide for adjustments to the tender price due to inflation.

15. We estimate the annually recurrent expenditure for the project to be $207,000.

PUBLIC CONSULTATION

16. We consulted the Traffic and Transportation Committee of the Kwai Tsing District Board on 21 June 1996 and received no adverse comments on the proposal.

17. We gazetted the proposed works under Roads (Works, Use and Compensation) Ordinance on 8 November 1996 and received no objections.

ENVIRONMENTAL IMPLICATIONS

18. In April 1996, the Director of Environmental Protection conducted an Environmental Review which concluded that the proposed works would have no long term environmental impacts and therefore no Environmental Impact Assessment was required. For short term impacts, we will control noise, dust and site run-off during construction by implementing of mitigation measures to be included in the works contract.

LAND ACQUISITION

19. This project does not require land acquisition.

BACKGROUND INFORMATION

20. We upgraded 175CL to Category B in March 1992.

21. We engaged consultants to undertake the investigations and design for the proposed works and charged the cost of $1.9 million to 41CL "Tsing Yi development : investigations and consulting engineers’ fees". The consultants have completed the detailed design and drawings. We plan to commence construction in September 1997 for completion in April 1999.

175CL - Tsing Yi development - remaining works

Breakdown of the estimate for consultants’ fees for construction stage

*MPS = Master Pay Scale

Notes

1. A multiplier factor of 3 is applied to the average MPS point to arrive at the full staff costs including the consultants’ overheads and profit, as the staff will be employed in the consultants’ offices. A multiplier factor of 2.1 is applied to the average MPS point in the case of site staff supplied by the consultants. (At 1.4.95, MPS pt. 40 = $51,440 p.m. and MPS pt. 16 = $17,270 p.m.)

2. The figures given above are based on estimates prepared by the Director of Territory Development. The consultancy work for this project is included in the overall consultancy agreement for New Town Development at Tsing Yi.
