The Singapore Land Transport Authority (LTA) has awarded the final civil contract for the Cross Island Line (CRL) Phase 2. The civil contract for the design and construction of tunnels between Maju station (CR16) (working name) and Clementi station (CR17) was awarded to Sinohydro Corporation Limited (Singapore Branch). Valued at around S$199M, this contract completes LTA’s appointment of contractors for the nine civil contracts under CRL Phase 2.
The twin bored tunnels, each extending 1.4km between CR16 and CR17, will be constructed beneath key infrastructure such as the Sungei Ulu Pandan canal. The ground conditions in this area predominantly consist of hard sedimentary rock, for which a slurry TBM will be used to construct the tunnels. Real-time monitoring and safety measures will be implemented during the tunnelling works. LTA and the contractors will closely monitor the works and implement necessary mitigation measures to ensure ground stability as well as safe and timely completion, while minimising any impact on nearby stakeholders and infrastructure.
Construction works are expected to start in the fourth quarter of 2024 and passenger service for CRL Phase 2 is targeted to commence in 2032.
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 29km long, and comprises 12 stations. Construction works have commenced and are targeted to be completed by 2030. CRL Phase 2, announced in 2022, is approximately 15km and comprises six underground stations. Engineering studies for the CRL Phase 3 are ongoing and more details will be announced after these studies are completed.
