Singapore’s Land Transport Authority has awarded a design-build contract for a stretch of the North-South Corridor to Japanese firm Penta-Ocean Construction and Bachy Soletanche Singapore.
Construction on the 1km tunnel between Suffolk Walk and Novena Rise, estimated to be worth around US$584 million, will start by the first quarter of 2019, according to a statement by the Authority.
Works by the joint venture will include an underground pedestrian network, pedestrian overhead bridges, bus stops, sheltered walkways and cycling paths.
The 21.5km North-South Corridor, to be completed in 2026, is a mostly underground expressway with dedicated bus and cycling lanes running between Admiralty Road West and the area close to Ophir Road and East Coast Parkway.
Bachy Soletanche Singapore is part of the UK-based geotechnical and civil engineering business Bachy Soletanche, a specialist in geotechnical and civil engineering works.
Penta-Ocean Construction and Bachy Soletanche Singapore have worked together before on Singapore transportation projects, including a section of the 5km Marina Coastal Expressway that was opened in 2013. It links the eastern and western parts of Singapore to the New Downtown area being developed in the Marina Bay area. With five lanes in each direction, the expressway is a major commuter route.
