Gamuda Berhad Singapore branch Wai Fong Construction has secured $467m contract to design and construct Defu station and tunnels.
China Communications Construction has secured $397m contract to design and construct Tampines North station and tunnels.
Contractors are expected to begin construction works on Defu and Tampines North stations in the second quarter of this year.
Defu station is situated along Tampines road between Defu Avenue 1 and Defu Avenue 2, and the Tampines North station is situated between ampines Link and Tampines Ave 11.
Due to thick and soft layers of marine clay, and soil-like material with sandy and silty clay, excavation works at these areas are anticipated to be challenging for the contractors.
In a statement, LTA said: “Safety measures will be taken when carrying out the Earth Retaining and Stabilising Structure and deep excavation works to ensure stability of the ground and surrounding structures.
“LTA and the contractors will monitor the works closely to ensure that they are carried out safely and minimise any inconvenience to stakeholders.”
The passenger service for CRL1, which is 29km long and includes 12 stations from Aviation Park to Bright Hill, is expected to be started in 2030.
Designed to benefit over 100,000 households, the CRL1 is said to serve residential and industrial areas in Loyang, Tampines, Pasir Ris, Defu, Hougang, Serangoon North and Ang Mo Kio.
In December last year, the LTA awarded a contract worth $780m for a joint venture (JV) between Shanghai Tunnel Engineering and LT Sambo to design and construct tunnels between Aviation Park station and Changi East Depot of the CRL 1.
The CRL is eighth mass rapid transit (MRT) line in Singapore. By connecting major hubs such as Jurong Lake District, Punggol Digital District and Changi region, the CRL is designed to serve existing and future developments in the eastern, north-eastern and western corridors.
