All systems go for MTR's South Island Line and Kwun Tong Line Extension

The MTR Corporation has awarded seven major civil works contracts totalling more than HK$12 billion in value for the construction of the South Island Line (East) (SIL(E)) and the Kwun Tong Line Extension (KTE).

A joint venture between Laing O'Rourke, Kier and Kaden was awarded a HK$2.4 billion for Contract 901, a target cost contract for the construction of an integrated Admiralty Station. The works involve the construction of four new platforms underneath the existing Admiralty Station (ADM), two for SIL(E) and two for the future Shatin-to-Central Link. Major elements of the works include a new extension east of the existing station; station cavern and overrun tunnel; underpinning of existing finger tunnels; diaphragm walls and secant pile walls; and relocation or demolition of various existing station facilities.

A HK$1.28 billion lump-sum contract was awarded to Nishismatsu Construction Co Ltd for Contract 902, for the construction of the Nam Fung Tunnel and ventilation buildings. The project calls for drill-and-blast tunnel works from Admiralty Station to the Nam Fung ventilation building; construction of overrun stub tunnels at the Hong Kong Park ventilation building; provision, management and operation of explosives magazine and associated facilities at Chung Hom Shan; construction of two ventilation buildings and an enclosed railway box structure and piers; as well as various modification and reinstatement works and temporary traffic management schemes.

As reported last month (HKE July 2011, pg 5), two contracts totalling HK$4.26 billion went to Leighton Asia, one in joint venture with John Holland Pty Ltd. Contract 903, a target cost contract worth HK$2.51 billion, was awarded to Leighton for the construction of a 2 km viaduct, the Aberdeen Channel Bridge, Ocean Park Station and Wong Chuk Hang Station.

Contract 904, worth HK$1.75 billion, went to Leighton-John Holland for the construction of underground stations at Lei Tung and South Horizons; cut-and-cover tunnels from Aberdeen Channel Bridge to Ap Lei Chau; drill-and-blast tunnels and overrun tunnels; the design and construction of a conveyor belt system for a barging point at Lee Nam Road; and other miscellaneous works.

The Chun Wo-Hip Hing Joint Venture won a HK$324.83 million contract (Contract 907) for site formation and piling works at Wong Chuk Hang Depot.

Two contracts were awarded for the construction of KTE: a HK$2.97 billion contract to Nishismatsu Construction Co Ltd (Contract 1001) for the construction of the Yau Ma Tei to Whampoa Tunnels and Ho Man Tin Station; and a HK$856.15 million contract (Contract 1002) to Chun Wo-Hip Hing JV for the construction of Whampoa Station and overrun tunnel.

SIL(E) will be a 7 km long medium-capacity railway linking Admiralty Station with South Horizons Station with intermediate stations at Ocean Park, Wong Chuk Hang and Lei Tung. KTE will be a 2.6 km long extension of the existing Kwun Tong Line to Ho Man Tin and Whampoa.

Both projects are scheduled for completion in 2015.
