Woh Hup Engineering Pte Ltd has won the design and construction of DEI station on Sungei Kadut Avenue. The contract, valued at around S$285m (US$224.7m), includes constructing a vehicular bridge to extend Choa Chu Kang North 7 and a pedestrian link-bridge over Pang Sua Canal to enhance connectivity between Yew Tee, DE1 station and the Rail Corridor.
Woh Hup Engineering Pte Ltd is a Singapore-registered company specialising in infrastructure and building projects. It is currently involved in the design and construction of Punggol Interchange station for the Cross Island Line (CRL) Punggol Extension (CPe), and CR3 station for CRL Phase 1. Woh Hup Engineering Pte Ltd was also awarded the contract for tunnelling works between DE1 station and DE2 interchange station for the DTL2e project.
A joint venture between Samwoh Corporation Pte Ltd and China Communications Construction Company Ltd (Singapore branch) has been awarded the design and construction of the NS6/DE2 interchange station. The approximately S$450m (US$354.8m) contract involves the construction of an underground DE2 station on the DTL and a connected aboveground NS6 station between the Yew Tee and Kranji stations on the North-South Line (NSL).
Samwoh Corporation Pte Ltd’s completed projects include the Sentosa Gateway Tunnel, and the flyover slip road from Seletar West Link to Seletar Expressway.
China Communications Construction Company is currently involved in the construction of CR6 Tampines North station, CR15 King Albert Park and CR17 Clementi interchange stations on the Cross Island Line, JS8 Boon Lay interchange station on the Jurong Region Line, and the Johor Bahru – Singapore Rapid Transit System Link viaduct and tunnels. It is also involved in the construction of the Jurong East Integrated Transport Hub.
The DE1 and NS6/DE2 stations will be constructed concurrently using earth retaining and stabilising structures because of the expected complex ground conditions, such as hard granite. The works will be carried out within a constrained workspace and in close proximity to the NSL.
Construction works are expected to start in the second quarter of this year and the DTL2e is scheduled to open in 2035.
DTL2e comprises three stations: DE1, DE2 and NS6. When completed, DTL2e will improve rail connectivity in the north-western region, and shorten journey times between north and north-west Singpore. It will provide improved access to existing and new growth areas such as Yew Tee and the future Sungei Kadut Eco-District, as well as amenities such as the Rail Corridor and Pang Sua Park Connector.
