North-South Corridor Contract N102

Instrumentation and monitoring for 21.5 km North-South Corridor of the underground highway section was required for risk assessment. The corridor connects Marina Bay in the southern part and the northernmost Woodland area in Singapore. It is being built as an underground highway between two metropolitan subway lines (DTL and NEL). The project includes construction of two-way six lanes of cut & cover underground tunnel 1.42 km with 4 entry/exit slip roads. Section N102 is considered the most challenging section because the location for this section of the underground expressway is crisscrossed by roads on the ground and two subway lines (DTL and NEL) underground. Notably, the two-way six-lane expressway will be constructed just one meter above the NEL Line.

Encardio-rite supplied around 220 number of piezometer for the project through marketing associate in the region. 

All piezometers (100%) are operating satisfactorily until today.
