MTR Shatin to Central Link – Causeway Bay Typhoon Shelter to Admiralty Tunnels – Contract No. 1128

2014

Dragages was selected to construct one of Hong Kong’s most technically challenging tunnels – part of the 6km extension of the ongoing Shatin to Central Line – from Kowloon to the transit hub on Hong Kong Island.
 
The main scope and challenge of the project is to construct the Eastern Tunnels and Western Tunnels by Tunnel Boring Machine (TBM), as both tunnels go through the city’s busiest districts. Meticulous project planning is essential in aiding the TBMs to navigate through a large volume of pile obstructions and utilities with zero interruption of services to citizens. To cope with the complex geological conditions, two different types of TBMs are being employed for excavation – a slurry TBM and an Earth Pressure Balanced (EPB) TBM.
 
The construction of the South Ventilation Building requires careful effort as well, as the existing Police Officers’ Club (POC) needs to be demolished and reprovisioned on the top of the South Ventilation Building.
