Hong Kong’s MTR has awarded the final major tunnelling contract, C704, on its 3km long West Island Line, to the Gammon/Nishimatsu JV. Under a target cost arrangement, the JV will excavate 2.1km of twin tube tunnel between Sai Ying Pun and Kennedy Town by drill and blast, and also construct cavern stations at Sai Ying Pun and Hong Kong University.
This is Gammon Construction’s second award on the West Island Line, having picked up the US$170M, lump sum, C705 last month for the cut and cover construction of Kennedy Town Station, and drill and blast excavation of the overrun tunnel.
Already up and running is the first of the tunnelling contracts, C703, which was awarded on the 12th August last year to the Dragages/Maeda/BSG JV. The US$200M target cost contract includes the TBM construction of the twin tunnels between Sheung Wan and Sai Ying Pun Stations, and also the demolition of an existing overrun tunnel that will be carried out by a specially designed Tunnel Dismantling Machine.
The Chief Executive in Council authorized the West Island Line (WIL) under the Railways Ordinance resulting in it being gazetted in March 2009.
In May 2009, the Executive Council endorsed the funding arrangement of the MTR WIL Project and funding approval was obtained from the Legislative Council in July 2009.
The construction of WIL commenced in July 2009 and will be completed in 2014.
