Singapore’s Land Transport Authority (LTA) has awarded the civil contract for the design and construction of West Coast station and tunnels under the Cross Island Line Phase 2 (CRL2) to Gamuda Berhad Singapore Branch, at a contract value of around S$510 million.
The CRL West Coast station is an underground station located along West Coast Road. Given its proximity to existing infrastructures such as residential and commercial buildings, LTA said necessary traffic and utilities diversion works will be implemented in phases to mitigate the impact to residents and other stakeholders.
The works are expected to be challenging, according to LTA, due to the mixed ground conditions at this location, which include soft marine clay and hard sedimentary rocks. To ensure safety and ground stability, earth retaining and stabilising structures will be built prior to excavation and construction of the station structures.
Construction works for the CRL West Coast station are expected to start in the first quarter of 2024, with passenger service for CRL Phase 2 targeted to commence in 2032.
Gamuda Berhad has an established track record in infrastructure and residential projects both locally and abroad. The company is currently involved in the design and construction of CRL Defu station and tunnels, as well as the Gali Batu Bus Depot.
The CRL is Singapore’s eighth MRT 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. The CRL will have almost half of its stations as interchanges with other rail lines, making it easier and more convenient for commuters to travel across the rail network.
The fully underground CRL will be constructed in three phases. Announced in 2019, CRL Phase 1 is 29 km long and comprises 12 stations. Construction works for the Phase 1 have commenced and are expected to complete by 2030. CRL Phase 2, announced in September 2022, is approximately 15 km long and comprises six stations. Engineering studies for CRL Phase 3 are ongoing and more details will be revealed later.
