MTR Corp has appointed Maunsell AECOM as design consultant for its South Island Line (East) in Hong Kong, which will involve approximately 3.5km of tunnelled route.
The consultant has a nine month contract to work with the client to produce the most cost-effective design solution for the link and develop it to preliminary design stage. The 7km long route also involves cut and cover tunnels as well as viaducts.
Work on the design contract began last month. Commercial terms of the contract were not disclosed.
South Island Line (E) has an estimated cost of more US$900M and will run from South Horizons, via Lei Tung, Wong Chuk Hang and Ocean Park, to the key interchange of Admiralty station.
The line will link the existing Tsuen Wan Line, the Island Line, the future Shatin-to-Central Line (at Admiralty station), and an interchange for the future South Island Line (West) will be at Wong Chuk Hang.
Maunsell Aecom’s design will address interfacing the four lines at Admiralty station as well as soft ground tunnelling needs at Nam Fung portal, some major faults, and urban excavation in addition to various site constraints. In addition, cavern excavation will be required at Lei Tung station.
Approval for the link was given by the Government of Hong Kong in December 2007.
