The construction works for Aviation Park MRT station will begin in the first quarter of 2022, with passenger service projected to commence in 2030, the Land Transport Authority (LTA) announced in a press release on Monday (Nov 8).
$320 Million Contract Awarded for Design & Construction of Aviation Park MRT station
Hock Lian Seng Infrastructure Pte. Ltd. is awarded the civil contract for the design and construction of the Aviation Park MRT station and tunnels for the Cross Island Line (CRL).
Aviation Park MRT station will be an underground MRT station located adjacent to Changi Coast Road and Aviation Park Road.
Company has a “strong track record of undertaking infrastructure and building projects in Singapore”
LTA said that the company has a “strong track record of undertaking infrastructure and building projects in Singapore.”
It was previously involved in the construction of both the Kim Chuan Depot (KCD) and Marina Bay MRT station for the Circle Line (CCL), and are currently involved in the construction of Maxwell MRT station for the Thomson-East Coast Line (TEL), said LTA.
Safety measures & strict compliance to regulations will be in place during construction works
LTA said that safety measures to ensure the stability of the ground and surrounding structures will be taken when carrying out the Earth Retaining and Stabilising Structure and deep excavation works.
Ground conditions in that area are expected to be challenging due to thick layers of underlying marine clay.
Located near Changi Airport, aviation height restrictions during construction works have to also be complied with strictly, said LTA. Both LTA and the contractor will monitor the construction works closely to ensure that they are carried out safely.
$446 Million Contract Awarded for Design & Construction of Bored Tunnel
Nishimatsu Construction Co., Ltd have been awarded the civil contract for the construction of a facility building with underground basements.
This will be catered for the electrical and mechanical requirements of the CRL.
Company has a “strong track record of undertaking infrastructure, building and tunnelling projects locally and abroad”
LTA said that the company has a “strong track record of undertaking infrastructure, building and tunnelling projects locally and abroad.”
It had constructed the tunnels between Ubi MRT station and Kaki Bukit MRT station, and the reception tunnels to the Tai Seng Facility Building along the Downtown Line (DTL).
The company is currently involved in the construction of Gardens by the Bay MRT station for the TEL and Keppel MRT station for the CCL.
Largest tunnel boring machine ever to be deployed in Singapore
LTA said that a large-diameter Tunnel Boring Machine (TBM), measuring about 12.6 metres in diameter, will be used to construct a single 2.9-kilometre long tunnel with two tracks in it.
It added that this will be the largest TBM ever to be deployed in Singapore and it is expected to increase work productivity and reduce manpower requirements.
The tunnel will be constructed at an approximate depth of 35 metres below ground level, and is almost 50 metres underground at its deepest, LTA said.
Construction works for the tunnel to begin in December 2021
LTA said that the tunnelling will be carried out in ‘mostly Old Alluvium,’ which is predominantly soil-like material comprising sandy and silty clay. Thus, the TBM cutting equipment is expected to receive some wear due to the abrasive ground condition.
As such, LTA and the contractor will be monitoring the TBM’s progress to ensure all works are carried out safely and timely with minimal impact to existing structures, including the shophouses in the area.
Shorter Travelling Times with the Cross Island Line
The first stage of the Cross Island Line (CRL1) which comprises 12 stations, will span from Aviation Park to Bright Hill. LTA mentioned that the CRL1 will benefit over 100,000 households, serving both residential and industrial areas along regions of Tampines, Pasir Ris, Hougang and Ang Mo Kio.
Commuters can expect the CRL1 to reduce travelling times from Ang Mo Kio to Aviation Park, from 105 minutes to 35 minutes. LTA also estimated that it would take 65 minutes to travel from Tavistock to Aviation Park, from the 95 minutes travelling time of today.
The CRL would be Singapore’s eighth MRT line, connecting the country’s major hubs such as Jurong Lake District, Punggol Digital District and Changi. When fully completed, it will serve existing and future developments in the eastern, north-eastern and western corridors.
