SINGAPORE: The Land Transport Authority has awarded Alstom Transport an S$238·5m contract for track work on the Downtown Line now under construction.

The contract awarded on January 30 covers the design, supply and installation of 70 km of track with a 750 V DC third rail power supply on the first two phases of the Downtown Line. Other bids had been submitted by CTCI Corp, TSO and a joint venture of Balfour Beatty and Gammon.

The Downtown Line will link the northwestern and eastern areas of the island to the Central Business District and Marina Bay.

The 16·6 km Phase II to follow in 2015 will extend the line to Petir, adding a further 12 stations. Slab track will be used on the running lines, with ballasted track in the depot.

The 19·1 km Phase III from Chinatown to Expo is currently at the design stage and is expected to open in 2016. Parsons Brinckerhoff has been awarded a S$22·2m contract to provide electrical and mechanical consultancy for the final stage, while Arup has a S$45·7m contract for architectural and engineering consultancy.
