With the award of the S$526m (US$389m) contract, Singapore’s Land Transport Authority (LTA) has now appointed contractors for all 12 stations for CRL1.
The LTA says Penta Ocean has a strong track record of undertaking infrastructure, building and tunnelling projects in Singapore. The company previously worked on Bright Hill station along the Thomson–East Coast Line (TEL) and it is currently constructing the station, tunnels and customs, immigration and quarantine building for the Johor Bahru–Singapore Rapid Transit System Link as well as the tunnel between Suffolk Walk and Novena Rise for the North-South Corridor.
Construction works for CRL1 Bright Hill station are expected to start in the second quarter of 2022, and passenger services are due to commence in 2030. The interchange station will enable commuters to transfer between CRL and TEL. It will be 20m deep and the TBMs will encounter mainly Bukit Timah granite.
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. Almost half of the stations will be interchanges.
The 29km CRL1 comprises 12 stations from Aviation Park to Bright Hill. The LTA says studies on the details of subsequent CRL phases are ongoing.
