As the LTA moves ahead with more transit, WSP is providing mechanical/electrical consultancy services for Phases 2 and 3 of the Downtown Line. When completed in 2015 and 2017 respectively, this line will enable direct travel from northwestern and eastern areas of Singapore to the city center.
Phase 2 involves 12 underground stations, three of them interchange stations, for a total route length of 10.4 miles (16.6 kilometers). For Phase 2, we are coordinating nine design-build contracts as well as providing project management, design, tender support and construction stage services for the mechanical and electrical (M&E) work for the stations and associated tunnels.
Phase 3 has a total route length of 14.3 miles (23 kilometers) and comprises 16 underground stations (three of which are interchange stations) and a fully underground 66kV electrical substation. The Downtown Line is a fully underground, automatic and driverless line.
The Thomson Line, currently in preliminary design, will run 19 miles (30 kilometers) from Marina Bay in the south, through the city center to the Woodlands in the north. We are lead electrical and mechanical consultant for the line's northern section package, which consists of 11 stations (including two station shells) and one depot. The work also involves a comprehensive fire engineering study as well as special elements to enable the stations to be used as civil defense centers.
