Singapore’s Land Transport Authority (LTA) has awarded the final civil contract for the Cross Island Line-Punggol Extension (CPe).

A joint venture of CES_SDC Pte Ltd and Chip Eng Seng Contractors will complete the S$562m (US$427m) contract for the design and construction of Elias station and tunnels.

The 7.3km CPe will comprise four stations – Punggol, Riviera, Elias, and Pasir Ris.

Elias station will be built at a depth of about 40m and have five entrances. The geology is old alluvium, a predominantly soil-like material comprising sandy and silty clay. A TBM will build a pair of tunnels, each approximately 1.4km long, linking Elias and Pasir Ris stations, with the deepest section approximately 50m below ground.

Construction works are expected to start in the second quarter of this year, and the service should be open to passengers in 2032.

The Cross Island Line (CRL) is Singapore’s eighth MRT line. It will be constructed in three phases. CRL Phase 1 is 29km long and comprises 12 stations from Aviation Park to Bright Hill. Construction is under way and is schedule to be completed by 2030. CRL Phase 2, announced in September 2022, is approximately 15km and comprises six underground stations. Engineering studies for the CRL Phase 3 are ongoing.
