Singapore: The Land Transport Authority (LTA) stated in a press release on Monday (November 8) that the construction of the Aviation Park Station is expected to begin in the first quarter of 2022, and passenger services will begin in 2030.
The station is located beside Changi Coast Road and Aviation Park Road.
Fuliansheng Infrastructure has been awarded a contract for the design and construction of the Aviation Park station and tunnel, with a contract value of S$320 million.
According to the Land Transportation Bureau, the company “has a good track record in undertaking infrastructure and construction projects in Singapore” and has previously participated in the construction of the Jinchuan Depot on the Circle Line (CCL) and the Marina Bay Station along the CCL. It is currently involved in the construction of Maxwell Station along the Thomson-East Coastline (TEL).
“The ground conditions in this area are expected to be challenging because they consist of thick layers of seafloor clay,” LTA said.
“In the construction of retaining and stabilizing structures and deep foundation pits, safety measures will be taken to ensure the stability of the ground and surrounding structures.”
Given its proximity to the Changi Airport compound, these projects will be carried out in strict compliance with regulations, including aviation altitude restrictions.
The authorities stated that LTA and the contractor will closely monitor the project to ensure safe progress.
Tunnel between Tampines North Station and DEFU Station
LTA also announced on Monday that it has awarded another civil contract for the design and construction of the first phase of the cross-island line (CRL1).
In addition to the contract for the design and construction of the Aviation Park Station, Nishimatsu Construction also won a civil construction contract worth S$446 million for the design and construction of the bored tunnel between Tampines North Station and Telford Station.
The contract includes the construction of a facility building with a basement to meet the electrical and mechanical requirements of CRL1. Construction of the bored tunnel is expected to start in December 2021.
A tunnel boring machine with a diameter of 12.6 meters is the largest tunnel boring machine in Singapore’s history and will be used to construct a 2.9 km long tunnel with two tracks. The tunnel will be about 35m below ground level and about 50m at its deepest point.
LTA stated: “Nishimatsu Construction is an established company with a good track record in undertaking infrastructure, construction and tunnel projects at home and abroad.”
“It has built a tunnel between Ubi and Kaki Bukit stations along DTL, and a receiving tunnel from DTL to the Dacheng Facility Building. It is currently participating in the construction of TEL’s Marina Bay Station and CCL’s Keppel Station.”
The authorities stated that LTA and the contractor will closely monitor the progress of the tunnel boring machine and ensure that all works are carried out in a safe and timely manner, with minimal impact on existing structures, including shophouses in the area.
CRL is Singapore’s eighth subway line. It will serve the existing and future development of the eastern, northeastern and western corridors, connecting major hubs such as the Jurong Lake District, Punggol Digital District and Changi District.
CRL will use nearly half of the stations as intersections with other railway lines.
The first phase of the CRL is 29 kilometers long and includes 12 stations from Aviation Park to Bright Hill. This will serve residential and industrial areas in Luoyang, Tampines, Pasir Ris, Defu, Hougang, Serangoon North and Ang Mo Kio.
