The Land Transport Authority (LTA) has awarded the civil contracts for the design and construction of two stations and associated tunnels, part of the Cross Island Line Phase 1 (CRL1) project in Singapore.

The first contract, valued at S$467 million and covering the design and construction of Defu station and tunnels, was awarded to Gamuda Berhad Singapore Branch – Wai Fong Construction Pte Ltd Joint Venture.

The second contract covers the design and construction of Tampines North station and tunnels, totalling around S$397 million. It has been awarded to China Communications Construction Company Limited (Singapore Branch).

The Defu station is located along Tampines Road between Defu Avenue 1 and Defu Avenue 2, while the Tampines North station is located between Tampines Link and Tampines Ave 11. LTA said the excavation works at these areas are expected to be challenging, as their ground conditions comprise thick and soft layers of marine clay as well as a soil-like material consisting of sandy and silty clay.

Safety measures will be taken when performing the earth retaining stabilising structure (ERSS) and deep excavation works to ensure stability of the ground and surrounding structures. LTA and the contractors will monitor the works closely to ensure they are carried out safely and minimise any inconvenience to stakeholders.

Construction works on both stations are scheduled to start in the second quarter of this year, with passenger service for CRL1 slated to commence in 2030.

Gamuda Berhad has vast experience in infrastructure and residential projects locally and abroad. The company is currently involved in the construction of Gali Batu Bus Depot in Singapore.

In Singapore, the company is currently involved in the construction of two stations on the Jurong Region Line (JRL) plus road tunnels between Victoria Street and Kampong Java Road for the North-South Corridor.
