Singapore MRT Turas West Extension Project involved the construction of a twin level interchange station EW30 and 6 Km of elevated twin viaducts connecting to the existing Boon Lay extension.

In 2014 Shanghai Tunnel awarded SDI a subcontract for assembly, relocation, operation (segment and beam erection), maintenance and dismantling of both Launching Gantries.

Commencing in January 2014, SDI mobilized a team over 40 staff and workers for the project. SDI completed erection of over 200 spans and multiple relocations of the launching gantries within 18 months with no major incidents or reportable accidents.
