The middle stages of the Circle Line were where much of our team's Singapore experience was forged. Across contracts C852, C853, C854 and C856, Herrenknecht and Kawasaki machines — both EPB and slurry — drove the orbital line's tunnels through the island's varied geology.
Working under Taisei Corporation and other main contractors, our members handled everything from machine assembly to cutter interventions to end-of-drive recovery, building the habits of safety and precision that define our company today.
