Basic Information 1.1 Project Title Reconstruction of Wong Shek Public Pier, Sai Kung North, Tai Po 1.2 Purpose and Nature of the Project The main purpose of the project is to reconstruct the existing Wong Shek Public Pier at Sai Kung North of Tai Po. Recent inspection by the Civil Engineering Department (CED) reveals that the pier, which was constructed using prestressed concrete members, is in a deteriorating condition with severe corrosion in the prestressed tendons. As a result, some tendons have broken. Reinstating them to acceptable conditions is very difficult and costly. Even with such costly repair, the long term durability of the structure will still be limited. The pier users will be at risk if the pier is not to be replaced. It is therefore proposed to reconstruct the pier as well as take the opportunity to enhance the appearance of the pier and to provide an attractive focal point at its location. 1.3 Name of Project Proponent Economic Development and Labour Bureau is the policy bureau. CED is the client department. The Technical Services Division of CED is the works agent for the planning, detailed design and works supervision for the project. 1.4 Location of Project, Scale of Project and History of Site The existing pier was built in 1960s. It is a public pier for kaitos and pleasure vessels operating in Sai Kung North area. The proposed new pier is located adjacent to the existing pier. The proposed structural form of the new pier should be open type suspended deck sitting on piles. Drawing Nos. TS 2185A and TS 2186A showing the location and general arrangement of the new pier are attached at Appendix A and B respectively. The scale of the works is small and the major work items are as follows:- (1) Provision of temporary berthing and mooring facilities until commissioning of the new pier; (2) Drilling of about 46 numbers of pre-bored H-piles; (3) Construction of about 600 m2 reinforced concrete deck, with 3 sets of landing steps, fenders, one navigation light and public lighting; Technical Services Division, Civil Engineering Department Page 3 Reconstruction of Wong Shek Public Pier, Sai Kung North, Tai Po Project Profile (4) Construction of roof; and (5) Cutting of the existing pier into several segments and delivery to designated site(s) as artificial reefs (approximately 350m3) after the commissioning of the new pier. No dredging and spoil dumping will be involved. A silt curtain will be installed prior to carrying out the marine works. 1.5 Number and Types of Designated Projects to be covered by the Project Profile The project is a designated project under Section Q.1 of Schedule 2, Environmental Impact Assessment (EIA) Ordinance, as the proposed site is within an existing country park, namely the Sai Kung East Country Park. 1.6 Name and Telephone Number of Contact Persons Technical Services Division Civil Engineering Department Mr Y W Li, Senior Engineer, Tel: 2762 5576 Fax: 2714 2054 Email: [email protected] Mr Johnny C H Chan, Engineer, Tel: 2762 5562 Fax: 2714 2054 Email: [email protected] 1.7 Estimated Cost $ 28.0 million (at September
