Structural testing and monitoring in Singapore's Deep Tunnel Sewerage System (DTSS)

Monitoring the structural integrity of the Deep Tunnel Sewerage System (DTSS)

Singapore DTSS project will deliver 40 km of deep tunnels and 60 km of link sewers by 2025 in Western Singapore. Prototypes of the new structures and a Tunnel Integrity Monitoring System (TIMS) Network are under development as the tunnel boring machines do their work.
More than 100 km of fiber-optic sensors will be embedded in the tunnel walls, monitoring structural health during and for decades after construction. The precision of the fibrisTerre system’s measurement enables 3D shape sensing.
