Singapore’s The Land Transport Authority (LTA) awarded a joint venture of Shanghai Tunnel Engineering Co (Singapore) and Obayashi Corporation the contract for the design and construction of CRL Turf City station and tunnels.
The construction works for the station are expected to start in the third quarter of 2024, and passenger service for CRL Phase 2 is targeted to commence in 2032.
The SGD 530 million (USD 392 million) contract includes the construction of the needed tunnels under the tunnels under the Cross Island Line phase 2 which will provide station’s connections.
CRL Turf City station will be build underground located along Turf Club Road, near the former Grandstand. The construction works are expected to be challenging due to the varying soil conditions in the area, in particular the harder ground conditions of the Bukit Timah granite formation which requires the use of specialised techniques to carry out excavation works safely. Before commencing excavation and construction works for the station structure, earth retaining and stabilising structures will be installed to ensure safety and ground stability.
LTA and the contractors will monitor works closely and implement necessary mitigation measures to ensure safe construction with minimal impact to nearby stakeholders and infrastructure.
The joint venture and its two member companies have established track records in local rail projects. The JV had earlier been awarded the contract for the design and construction of the bored tunnel between Fairways Drive and Sin Ming Walk under the CRL2 in December 2022. Currently, Shanghai Tunnel Engineering Co (Singapore) is in the final stages of completing Katong Park and Bayshore stations on the Thomson-East Coast Line (TEL), having also completed the construction of TEL Shenton Way station. Obayashi Corporation previously constructed the North East Line Dhoby Ghaut station.
The CRL is Singapore’s eighth MRT line and will serve existing and future developments in the eastern, north-eastern and western corridors linking major hubs such as Jurong Lake District, Punggol Digital District and Changi region.
The CRL will have almost half of its stations as interchanges with other rail lines, making it easier and more convenient for commuters to travel across the rail network.
The fully underground CRL will be constructed in three phases. Announced in 2019, CRL Phase 1 is 29 km long, and comprises 12 stations. Construction works have commenced and are expected to complete by 2030. CRL Phase 2, announced in September 2022, is approximately 15 km and comprises six underground stations. Engineering studies for the CRL Phase 3 are ongoing and more details will be announced after these studies are completed.
