Shenton Way Excavation (III)

Bored tunnelling works between Marina Bay and Shenton Way stations have completed with the second and final drive of TBM 2 docking at the upper platform of the station. FSC works have commenced for the lower tunnel. The porous geological conditions around the former shoreline beneath Shenton Way has created an ongoing challenge for TBM 1 since its launch in April, which has progressed little since its main drive conversion.

Bulk of the station's structure has reached the under-lower platform level, with a final zone of excavation works due for completion within a month. Excavation and shoring works have commenced at entrance C.
