SOLDATA Geophysic survey enables successful TBM works in Singapore

May 2014

The TBM has successfully passed through the Rochor canal bridge’s foundation without any problem, following the geophysical survey by Soldata Geophysic on the MRT Downtown Line Stage 3 project in Singapore.

The Downtown Line is the fifth Mass Rapid Transit line in Singapore and the third line to be entirely underground. It will connect the North-Western and Central-Eastern regions to the new downtown of Singapore. At about 42 km long, it will be the longest driverless rapid transit line in Singapore, and it will serve more than half a million commuters daily. Stage 3 will aid commuters going to the industrial areas in the East.

A geophysical survey was undertaken, using mise-à-la-masse, parallel seismic and fluxgate magnetometry methods, to determine pile lengths in the tunnel vicinity as they may have been in conflict with the future tunnel works.
