A $189.8 million contract for the construction of new tunnels along the Thomson MRT Line has been awarded to a Japanese contractor, the Land Transport Authority (LTA) announced on Friday.
The civil contract, won by Shimizu Corporation, covers the building of tunnels from Seletar Expressway/Woodlands Avenue 12 to the new line's Springleaf Station.
Shimizu was previously involved in the design, construction and completion of the Circle Line/Downtown Line 1 tunnels undercrossing Marina Bay Reservoir, said the LTA.
Their latest work on the Thomson Line tunnels is set to start by the end of March this year and be completed in 2020.
The 30-km long Thomson Line will be fully underground and comprises 22 stations, including six interchange stations linking to the North-South-East-West Line, Downtown Line, North-East Line, and Circle Line.
