Singapore MRT Tuas 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 2013 NDF, SDI’s parent company, supplied two Overhead Launching Gantries for the project, one for the approach viaducts, one specially adapted for the station area. 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.
