About $757 million worth of contracts have been awarded by the Land Transport Authority (LTA) to two companies, for the construction of two stations for the upcoming Thomson MRT Line.

Construction works for the new Springleaf and Upper Thomson stations are expected to commence by the first quarter of 2014, and are scheduled to be completed by 2020.

Leighton Contractors and John Holland won the Springleaf station tender for $383 million. John Holland is currently also working on the construction of Downtown Line 3's Jalan Besar station.

The $374 million contract for the Upper Thomson station went to Sato Kogyo, which is also working on a number of Downtown Line projects, including the construction of Downtown Line 3's Mattar, Bencoolen and Bedok North stations. Sato Kogyo has a broad spectrum of construction projects under its belt, ranging from industrial facilities, commercial buildings and institutional landmarks to roads, bridges and tunnels.

The LTA said that when completed, these stations will connect the northern and central parts of Singapore through the North-South Line's Woodlands interchange, the Circle Line's Caldecott interchange and the Downtown Line's Stevens interchange.
