Work on the foundations and diaphragm walls for the West Kowloon Terminus in Hong Kong is now fully underway in bid to complete the new station by 2015.
High speed rail services that will arrive into the new station will connect Hong Kong with mainland China when the 142km Guangzhou-Shenzhen-Hong Kong Express Rail Link (XRL) opens in two years’ time.
The new Kowloon station will feature 15 platforms and is expected to serve 99,000 passengers per day but the terminus will all be below ground with a public park covering the area at surface.
The Hong Kong section of the XRL is being constructed by the MTR Corporation, with the Leighton and Gammon joint ventures contracted to build the West Kowloon Terminus Station North and the Southern Approach Tunnel.
Construction requires the open cut excavation of approximately 1.7M.m³ of earth to a depth of 33m and the use of 600,000m³ of concrete and 150,000t of reinforcement steel.
The footprint of the terminus is surrounded by a diaphragm wall and the ground engineering work includes the construction of 500 3.6m diameter bored piles to 40m depth and 5,000 rock socketed H-piles.
