LTA Awards Civil Contract for Design and Construction of Riviera Station under Cross Island Line-Punggol Extension2 October 2022
The Land Transport Authority (LTA) has awarded the civil contract for the design and construction of Riviera station under the Cross Island Line-Punggol Extension (CPe) to Taisei Corporation – China State Construction Engineering Corporation Limited Singapore Branch Joint Venture. The contract is valued at around $1.1 billion.
Taisei and China State Construction Engineering have a strong track record of providing design-and-build construction services which include rail stations and tunnels locally and abroad. The Joint Venture is currently involved in the construction of bored tunnels between Aviation Park station and Loyang station for the Cross Island Line Phase 1. Taisei was involved in the construction of Marina Bay station on the Thomson-East Coast Line. China State Construction Engineering is currently involved in the construction of Keppel and Cantonment stations for the Circle Line. The company previously completed Downtown Line’s Kaki Bukit and Geylang Bahru stations as well as North-South Line’s Canberra station.
3Construction works for the CPe Riviera station are expected to start in the first quarter of 2023, with passenger service targeted to commence in 2032.
CPe Riviera station, located along Punggol East and Punggol Central, will improve transport accessibility for residents. Safety measures, such as ground improvement works, will be implemented before the construction of earth retaining structure and excavation works start at the worksite. Traffic diversions to facilitate the construction works will be carried out in phases so that any inconvenience to residents and motorists is minimised.
A large-diameter Earth Pressure Balance (EPB) Tunnel Boring Machine (TBM), measuring about 12 metres in diameter will be used to construct a single 4.3-kilometre-long tunnel with two tracks in it. The tunnel will be constructed at an approximate depth of 25 metres below ground. LTA and the contractor will closely monitor the works to ensure that they are carried out safely and in a timely manner and minimise the impact to the nearby stakeholders.
The Cross Island Line (CRL) is Singapore’s eighth MRT line. It 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.
CRL will be constructed in three phases. Announced in 2019, CRL Phase 1 is 29 kilometres long, and comprises 12 stations from Aviation Park to Bright Hill. As of March this year, all the civil contracts for CRL Phase 1 had been awarded. Construction works have commenced and are expected to be completed by 2030. CRL Phase 2, announced in September 2022, is approximately 15 kilometres and comprises six underground stations - Turf City, King Albert Park, Maju, Clementi, West Coast and Jurong Lake District. Engineering studies for the CRL Phase 3 are ongoing and more details will be announced after these studies are completed.
The 7.3-kilometre CPe will comprise four stations, namely Punggol, Riviera, Elias, and Pasir Ris. It will provide better rail connectivity and greater accessibility for those living in eastern areas such as Pasir Ris and Tampines North as well as north-eastern areas such as Punggol and Sengkang. More than 40,000 households are expected to benefit from the CPe.
