- Slurry tunnel boring machine digs tunnels and uses a thick liquid (called slurry) to remove dirt and rocks.
LTA Awards Final Contract for CRL Phase 2
In a press release by LTA, the Land Transport Authority (LTA) has awarded the final civil contract for the Cross Island Line (CRL) Phase 2.
The announcement was made on 15 August 2024.
Sinohydro Corporation Limited (Singapore Branch), a Chinese state-owned company, won the contract.
The contract is worth about S$199 million.
Here are some key highlights to note:
- The contract is for tunnels between Maju station (CR16) and Clementi station (CR17).
- Construction will start in the fourth quarter of 2024.
- Passenger service for CRL Phase 2 is set to begin in 2032.
Details of the Tunnel Construction
According to LTA, “The civil contract for the design and construction of tunnels between Maju station (CR16) and Clementi station (CR17) was awarded to Sinohydro Corporation Limited (Singapore Branch).”
The project involves building twin bored tunnels.
Each tunnel will be 1.4 kilometres long.
A slurry tunnel boring machine will be used.
This is due to hard sedimentary rock in the area.
Take a look at this quick table for a clear overview:
| Aspect | Detail |
|---|---|
| Tunnel Type | Twin bored tunnels |
| Length of Each Tunnel | 1.4 kilometres |
| Boring Method | Slurry tunnel boring machine |
| Reason for Method | Hard sedimentary rock in area |
Power Supply Contract for CRL
LTA also awarded a separate contract for the CRL’s power supply system.
Siemens Mobility Pte Ltd and Concord Corporation Pte Ltd won this contract.
The power supply contract is worth about S$400 million.
It includes design and installation of electrical systems.
Here’s what the power supply contract covers:
- 66kV AC system
- 22kV AC system
- 1500V DC traction power supply system
Overview of CRL Phase 2
Cross Island Line Phase 2 will be about 15 kilometres long.
It will have six underground stations.
The CRL will connect existing and future developments across Singapore.
Almost half of its stations will be interchanges with other rail lines.
Impact and Implications
The Cross Island Line will enhance connectivity across Singapore.
It will improve local commutes.
The project shows Singapore’s commitment to expanding public transport.
Timeline and Future Plans
As quoted in LTA’s press release, “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 Cross Island Line will be built in three phases.
All phases will be fully underground.
The project aims to serve existing and future developments in Singapore.
The Cross Island Line Phase 2 marks a significant step in Singapore’s ongoing efforts to enhance its public transport network.
