Through its subsidiaries Dragages Hong Kong and Bouygues Travaux Publics, Bouygues Construction has won a contract worth HK$5.2bn (roughly €490M) from MTR Corporation for the construction of 2×2 tunnels that will form part of a 6km extension of the Shatin to Central Link.
These tunnels are among the major infrastructure projects currently under way in the city, connecting tourist sites and the financial district.
The two eastern tunnels, each approximately 540m long, will run from the south ventilation building and the new Exhibition station on the Shatin to Central Link. The two western tunnels, each approximately 450m long, will be bored between the Fenwick Pier emergency egress point and the existing Admiralty station. Bouygues Construction will also construct the ventilation building.

Philippe Bonnave, Deputy Chief Executive of Bouygues Construction, said: “Bouygues Travaux Publics has achieved the status of a global reference for underground works, following a series of technically complex projects, adapting to the most diverse geologies. This latest success further demonstrates our ability to meet technical challenges and carry out very large-scale infrastructure projects.”
To cope with the complex geological conditions a slurry TBM and an EPBM will be used. The works have just begun, and are scheduled to last for six years, with completion due in 2020. Some 500 people will be working on-site at peak periods.
The 17km Shatin to Central Link is designed to enhance the entire railway network of Hong Kong by connecting several existing railway lines. When complete, road traffic congestion will be relieved, and travelling time between the New Territories and the city centre will be reduced to around 40% of the time currently taken.
