Circle Line 6 — C882

Overview

Circle Line Stage 6 closed the final gap in Singapore's orbital MRT line, connecting HarbourFront to Marina Bay. Contract C882 deployed four 6.6-metre CREG earth-pressure-balance machines on twin-bore drives beneath some of the island's densest urban fabric.

Our team members served on the contract, handling machine assembly, production tunnelling and end-of-drive dismantling — often recovering machines in tight underground chambers where every lift had to be planned to the centimetre.

Scope of Works

• TBM assembly and launch for four EPB machines
• Mining crews for twin-bore drives
• Underground dismantling and machine recovery
• Invert and first-stage concrete works
