LTA awards contract for design and construction of underground station

The S$1.1bn (US$770m) contract has been won by a joint venture of Taisei Corporation and China State Construction Engineering Corporation Ltd Singapore Branch.

An EPBM with a diameter of around 12m will be used to construct a single bore 4.3km-long tunnel housing two tracks. The tunnel will be constructed at an approximate depth of 25m.

The joint venture is currently involved in the construction of bored tunnels between Aviation Park station and Loyang station for the Cross Island Line Phase 1. Taisei was involved in the construction of Marina Bay station on the Thomson-East Coast Line, while China State Construction Engineering is currently involved in the construction of Keppel and Cantonment stations for the Circle Line. The company previously completed Downtown Line’s Kaki Bukit and Geylang Bahru stations as well as North-South Line’s Canberra station.

Construction works for the CPe Riviera station are expected to start in the first quarter of 2023, with passenger service targeted to commence in 2032.

The Cross Island Line (CRL) is Singapore’s eighth mass rapid transit line. It will serve existing and future developments in the eastern, north-eastern and western corridors, linking major hubs such as Jurong Lake District, Punggol Digital District and Changi region.

CRL will be built in three phases. Announced in 2019, CRL Phase 1 is 29km long, and comprises 12 stations from Aviation Park to Bright Hill^. As of March this year, all the civil contracts for CRL Phase 1 had been awarded. Construction works are expected to be completed by 2030.

CRL Phase 2, announced last month, is approximately 15km long and comprises six underground stations – Turf City, King Albert Park, Maju, Clementi, West Coast and Jurong Lake District.

Engineering studies for CRL Phase 3 are under way.
