| Bouygues to construct two tunnels for the Hong Kong metro Through its subsidiaries Dragages Hong Kong and Bouygues Travaux Publics, Bouygues Construction has won a contract worth HK$ 5.2 billion (roughly €490 million) from MTR Corporation for the construction of 2x2 tunnels that will form part of a 6-kilometre 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 540 m 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 450 m long, will be bored between the Fenwick Pier emergency egress point and the existing Admiralty station. Bouygues Construction will also construct the ventilation building. To cope with the complex geological conditions, two different types of tunnel boring machines (TBMs) will be used: a slurry TBM and an earth pressure balanced TBM. 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 17-kilometre 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. write your comments about the article :: © 2014 Construction News :: home page |
