The western corridors of Singapore are about to change. With construction on the Jurong Region Line taking shape, Aurecon's design work across three stations and major civil structures is will leave a lasting positive impact enhancing accessibility for communities across Choa Chu Kang and Tengah.
Aurecon was appointed lead consultant to Shanghai Tunnel Engineering Co (Singapore) Pte Ltd (STEC), which won the contract from the Land Transport Authority (LTA), to design and construct Choa Chu Kang, Choa Chu Kang West and Tengah stations, including a 4.3 km viaduct between Choa Chu Kang and Tengah along Choa Chu Kang Ave 3 at a contract value of approximately S$465.2 million.
Aurecon worked closely with STEC's tender design and construction team to put forward an alternative design that optimises space in the rail corridor, ensuring more efficient construction and reduced traffic disruption for surrounding communities.
The JRL is Singapore's seventh MRT line, an elevated line approximately 24 km long with 24 stations, including three interchange stations at Boon Lay, Choa Chu Kang and Jurong East. In its initial years, the line is expected to serve 200,000 daily commuters, growing to more than 500,000 as future developments in the area are realised.
In addition to Contract J102, Aurecon is also working on Contract J109 – design and construction of JE4, JE6, JE7 stations and viaduct for the Jurong Region Line.
As lead engineering consultant for Contract J102, Aurecon delivered design and engineering services across three stations, each presenting distinct challenges in operational continuity, community sensitivity, and environmental responsibility. Watch this video series to learn how our experts navigated these unique challenges.
1:26Building within a live MRT station is one of the most demanding environments in urban rail engineering. At Choa Chu Kang station, Aurecon designed structural additions and alterations while the station remained fully operational.
2:15Engineering in the heart of an existing neighbourhood demands precision and community sensitivity. At Choa Chu Kang West Station, Aurecon navigated residential proximity, underground utilities, road median constraints, and active traffic.
1:45At Tengah Station, Aurecon’s environment team worked with nature groups to establish three wildlife crossings, protecting biodiversity and an ecosystem that supports 117 bird species, 12 mammals, and endangered species.
As lead consultant, Aurecon advises on detailed design encompassing civil structures, architecture and mechanical and electrical works. At Choa Chu Kang Station, one of the project's most complex challenges was undertaking addition and alteration works within a fully operational MRT station.
The JS1 station was constructed adjacent to and parallel with the existing Choa Chu Kang station, requiring design concepts that preserved structural integrity and met authority requirements – all while the Existing NSL CCK station remained open to the public.
At Choa Chu Kang West Station, proximity to HDB blocks and active traffic corridors demanded careful planning. A key engineering feature of the project is the 95-metre bridge spanning Brickland Road, which was constructed using the balanced cantilever method. This approach eliminated the need for intermediate columns within Brickland Canal, thereby preserving both the structural integrity and functionality of the canal. Aurecon also supported traffic diversion planning throughout construction.
Tengah Station presented a different kind of complexity. The station is a double-tier viaduct and double-deck elevated structure. Its connecting viaducts feature Singapore's first seven-girder span design and incorporate one of the tightest curves on Singapore's MRT network.
The viaduct alignment also passes through the centre of Tengah Forest, home to endangered species including Leopard Cats, Sunda Pangolins and Straw-headed Bulbuls. Aurecon's environment team collaborated with nature groups to establish three wildlife crossings before construction commenced, ensuring animals could continue to move freely between forest patches.
Aurecon appointed as an independent accredited checker for the structural design of the underground Mass Rapid Transit, Downtown Line Stage 3, Package C in Singapore.
Aurecon was appointed to conduct detailed structural analysis and lead the inspection of the Punggol and Sengkang LRT networks in Singapore.
As lead engineering consultant, Aurecon worked closely with DYJV’s design and construction team to co-create a robust and cost-efficient elevated metro design.
