Tunnel Engineering

Our tunnel engineering services play a key role in the development of solutions that deal with Singapore’s scarcity of land and constant search for solutions that do not congest the community and environment. ECAS provides tunnelling expertise in the planning, design, and construction supervision of tunnels for roads, rail, sewerage, power, and other utilities.

As underground work taps on numerous structures around it, our tunnelling professionals have experience in dealing with multiple parties affected by the construction and guarantee minimal disruption to operational services.

We have expertise in both Cut and Cover Tunnelling method using ERSS wall with multi-level struts and Bored Tunnelling method using Tunnel Boring Machine. We are experts in the design and supervision of NATM Tunnelling method using Shotcrete as sprayed lining during temporary stage. PLAXIS is widely used for the tunnel design for both bored tunnel and NATM tunnel.

Our experience in tunnel engineering extends to the accredited checking of Downtown Line and Thomson-East Coast Line MRT tunnels, the development of the Marina Coastal Expressway at Marina Wharf, and the construction of sewers and drains around Singapore.
