Singapore’s Land Transport Authority (LTA) has awarded the final civil contract for the Cross Island Line (CRL) Phase 2, along with a separate contract for the CRL’s power supply system.

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$199 million, this contract completes LTA’s appointment of contractors for the nine civil contracts under CRL Phase 2.

The twin bored tunnels, each extending 1.4 km between CR16 and CR17, will be constructed beneath key infrastructure such as the Sungei Ulu Pandan canal. According to LTA, the ground conditions in this area predominantly consist of hard sedimentary rock, for which a slurry tunnel boring machine (TBM) will be used to build the tunnels. Real-time monitoring and safety measures will be implemented during the tunnelling works.

Construction of the project is expected to start in the fourth quarter of 2024, with passenger service for CRL Phase 2 targeted to commence in 2032.

Sinohydro Corporation has been involved in both local and overseas infrastructure projects. In Singapore, the contractor previously built the Napier station on the Thomson-East Coast Line and is currently working on the construction of CRL Phase 1 Pasir Ris East station, as well as the construction of CRL Phase 2 Clementi station via a joint venture.

LTA has also awarded a separate contract, valued at around S$400 million, to Siemens Mobility Pte Ltd and Concord Corporation Pte Ltd Consortium for the design, supply, installation, testing and commissioning of the power supply system for the CRL.
