The Cross Island Line is Singapore's next great underground undertaking, and its central packages run through ground our people know ring by ring — the same granite and mixed-face conditions our crews drove on the Downtown Line and Thomson–East Coast Line.

Together with our affiliates Yu Sin Engineering Work Pte. Ltd. and Pro TBM Pte. Ltd., we are actively tendering for packages CR105, CR110, CR116 and CR117, offering complete TBM crews, mechanical teams and machine services.

For Zen Tunnel Engineering the pursuit is strategic as well as commercial: every drive our crews complete in Singapore deepens the bench of experience we will bring to the Dhaka Metro's underground phase.
