WSP has been working closely with Hip Hing Joint Venture and Hong Kong Government’s Architectural Services Department and Transport Department to offer structural and MEP solutions for this complex with a site area of 34,850m2. The facility will provide 30 inspection lanes for different kinds of vehicles, from motorcycle to most heavy-duty trucks and trailers, with a range of vehicle inspection facilities such as chassis dynamometers for commercial vehicles, tilting stability test platform, a track lane and test ramps for brake testing, a swept circle testing area and axle weigh bridges.
Site-sensitive structural solutions
Located at Sai Tso Wan, the industrial area on the western side of Tsing Yi, the project site is bounded by Tsing Sha Highway and Cheung Tsing Highway, the two key highways leading to the Tsing Ma Bridge, the essential link connecting to the Hong Kong International Airport. Hence, WSP’s structural engineers refined the design of the building to reduce the impact of deep excavation to these existing highway bridges at close proximity.
We also iterated the building and road levels to minimise the excavation works, while excavated materials are treated and reused as part of the filling materials to minimise the demand on imported fill, reducing the cost and environmental impact.
Moreover, as the site is located in a drainage reserve zone with a complex layout, we tailored the foundation design and column locations of this long span structure of over 20m to accommodate the required swept paths for the long vehicles and the space needed for conducting vehicle examinations.
Apart from offering cost effective and simple construction solution, WSP also brought extra values to our client. With limited building code reference available to some of the testing facilities, we leveraged our extensive engineering expertise and proposed applying relevant international practices for these parts of the complex.
