Singapore is a highly urbanized country with scarce land. To cope with the rising population, the government has continued to upgrade and expand the underground infrastructure in the construction of tunnel networks, both MRT tunnels and services tunnels. 

Wisescan is the key tunnel surveyor for construction of MRT tunnels and services tunnel (i.e. cable tunnels, sewerage tunnels and water tunnel). The services tunnels located deep underground are on a scale similar to the MRT tunnels.

Our project, DTSS T10 features the deepest shaft across all DTSS Phase 2 contracts measuring 66m deep and involves construction of an 8km tunnel that runs along Clementi Road, Farrer Road and the third one from West Coast Highway to Ayer Rajah Expressway. Our tunnel teams are stationed on site to provide dynamic surveying calculations to guide and drive the TBM (Tunnel Boring Machine) which are 3.5m, 4m and 6m in diameter) to travel in the predefined alignment, leading the tunnel to be constructed in the correct position and to optimize the tunnel breakthrough accuracy. 

At Wisescan, we have maintained an impressive track record in providing tunnelling survey in bored tunnel as well as cut and cover tunnel. To date, we have completed numerous islandwide tunnelling projects in both MRT tunnels and services tunnels.
