Singapore’s Land Transport Authority (LTA) awarded the joint venture of Taisei Corporation and China State Construction Engineering Corporation (Singapore) the civil contract to construct a tunnel for the Cross Island Line Phase 1 (CRL1).
SGD 356 million (USD 266.22 million) is the value of the contract which covers the construction of a 3.2 km tunnel between Aviation Park station and Loyang station. The works are expected to start in the second quarter of 2021.
For the first time, the Land Transport Authority will use a large-diameter tunnel boring machine to construct a single tunnel with two tracks.
The first phase of CRL is 29 km – long line with 12 stations from Aviation Park to Bright Hill. This section will serve residential and industrial areas such as Loyang, Tampines, Pasir Ris, Defu, Hougang, Serangoon North and Ang Mo Kio and benefit more than 100,000 households. With CRL1, common recreational spaces such as Changi Beach Park and Bishan – Ang Mo Kio Park will be more accessible by public transport. The studies on the details of subsequent CRL phases are ongoing.
The Cross Island Line is Singapore’s eighth MRT line and is scheduled to enter passenger transport services in 2030. The CRL1 will be the longest fully underground line at more than 50 km long. It will serve the existing and future developments in the eastern, western, and north-eastern corridors, linking major hubs such as Jurong Lake District, Punggol Digital District and Changi region.
When fully completed, the line is expected to have a daily ridership of at least 600,000 in the initial years, growing to one million in the longer term. The CRL will have almost half of its stations as interchanges with other train lines, making it easier and more convenient to travel across the rail network. It will be constructed in three phases.
Taisei Corporation is currently performing the construction works for the Marina Bay station and tunnels for the Thomson-East Coast Line while China State Construction Engineering Corporation (Singapore Branch) is working on the construction of Keppel and Cantonment stations for Circle Line 6, as well as tunnels for the North East Line extension. The company had previously completed the construction of Kaki Bukit and Geylang Bahru stations for Downtown Line Stage 3 and Canberra station for the North-South Line.
