AECOM Technology Corporation has announced today that it was appointed by MTR Corporation Limited (MTRCL) to design the cross-harbor tunnel of the North South Line (NSL), which forms part of the Shatin to Central Link (SCL). Under the contract, AECOM will produce the reference design and tender documentation, and provide support to MTRCL during tender and construction stages. This design-and-build project includes: a 280m section of cut-and-cover tunnels at the west side of the Causeway Bay Typhoon Shelter (CBTS); a 200m section of cut-and-cover tunnels adjacent to the existing seawall at Hung Hom Station (HUH); a 1.4km section of immersed tube tunnels (IMT) across Victoria Harbour linking the two cut-and-cover sections. The tunnel will comprise a minimum of 2 cells for rail plus additional cells for ventilation ducts for smoke control.
“We are honored to be part of this major rail project in Hong Kong and partner with our client to provide a convenient rail system to meet the growing demand between the north-east New Territories and urban areas,” said Tony Shum, AECOM’s president, Asia-Pacific. “This assignment demonstrates our strong commitment to MTRCL as our major client in Hong Kong, and will help to consolidate our position as the leading IMT designers in the region.”
The SCL consists of Phase 1 – East West Line and Phase 2 – NSL. The NSL is a 6km long extension of the East Rail Line from HUH across the harbour to Admiralty Station, forming the North-South rail corridor. Scheduled to be completed in 2020, it will become the fourth cross-harbour rail tunnel in Hong Kong.
