SINGAPORE’s Land Transport Authority (LTA) has awarded a $S 530m ($US 392m) construction contract for a new underground metro station. A joint venture of Shanghai Tunnel Engineering (Singapore) and Obayashi won the bid for the Turf City station on the Cross Island Line Phase 2 (CRL2) project.

Both companies have previously built stations on Singapore’s metro system, including Shenton Way (Shanghai Tunnel) and Dhoby Ghaut (Obayashi). This was an important consideration for LTA, which expects construction work to be challenging due to the varying soil conditions in the area, especially the harder ground conditions of the Bukit Timah granite formation that requires the use of specialised techniques to carry out excavation work safely.

Construction is expected to start in the third quarter of this year, while passenger services on CRL2 are not due to start until 2032. CRL is Singapore’s eighth metro line and runs fully underground. The 29km CRL1 with 12 stations is currently under construction and is due to be completed by 2030. CRL2 is 15km long with six stations. Engineering studies for CRL3 are now underway.
