2.        Both companies are established local construction and civil engineering contractors with strong track records in rail and infrastructure projects. CES_SDC was involved in the construction of Marina South station on the Thomson-East Coast Line, and is currently involved in the construction of two stations on the Jurong Region Line, as well as another station along the Cross Island Line-Punggol Extension.

3.        KTC Civil Engineering & Construction previously constructed Tampines interchange station on the Downtown Line and Orchard Boulevard station on the Thomson-East Coast Line. It is currently involved in the construction of Sungei Bedok station on the Thomson-East Coast Line, and two stations on the Cross Island Line.

Enhancement of Road Networks at Xilin Avenue, East Coast Parkway (ECP) and Tanah Merah Coast Road (TMCR)

4.        The contract covers the design and construction of new flyovers, tunnels and underpasses, as well as the widening of the existing Changi Airport Diversion Canal with new vehicular bridges and road enhancement works along Xilin Avenue, ECP, TMCR and Changi Coast Walk. When completed, the enhancements will provide full and direct road connectivity to the future Changi Airport Terminal 5 from ECP, PIE and Xilin Avenue.

5.        In addition, with the increased road capacity and enhancements, motorists can look forward to smoother traffic flow and more travel options to the Changi East region from the PIE and ECP.

6.        Apart from road infrastructure, new cycling paths will be built along Xilin Avenue and TMCR to enhance connectivity between Tampines, East Coast and the future Changi East developments. In addition, the existing pedestrian underpass (ECP Underpass No. 10) between ECP and the ECP Service Road will be upgraded and extended to serve both pedestrians and cyclists. Together with the existing Park Connector Network, these improvements will strengthen first- and last-mile connectivity and provide more seamless, barrier-free journeys along the Xilin–Changi East corridor.

7.        To facilitate these works, traffic diversion along the ECP, PIE and TMCR will be necessary due to site constraints and the construction sequencing required for the infrastructure works. Details of these diversions will be announced at a later date. LTA will take measures to mitigate inconvenience to motorists and minimise impact to greenery.
