Mott MacDonald’s operations in Singapore started in 1972 when we were invited by the government to investigate alternative ways of providing a crossing over the Kallang River. Since then we’ve been committed to supporting public and private sector clients in driving growth in the region, particularly in the rail, road, tunnels, buildings, infrastructure and energy sectors.

Telok Ayer Station, Singapore As designer for the 475m long Telok Ayer Station and associated tunnels, forming part of Singapore’s Downtown Line phase one, we found a cost-effective way to manage the risk associated with tunnelling over the top of an existing metro tunnel.

We focus on delivering projects that are designed safely, efficiently, durably and economically. Our team of over 350 experts are able to draw on the specialist knowledge of our global network of offices to provide our clients with a service that is second to none.


Our building and construction economics skills are well represented on several high profile projects. We’re building services consultant for the dynamic Jewel Changi Airport mixed-use development at Changi Airport that will feature leisure, retail, hotel and airport operations facilities.

Singapore’s Indian heritage is being celebrated by a new museum that has literally set new standards for sustainability. We were engaged by the country’s National Heritage Board to provide building services engineering and sustainable design in pursuit of a Green Mark Gold Plus award under the country’s Green Mark sustainable building rating system. Our solutions reduced the museum’s overall energy use by 28% compared to a code-compliant building.

For the Star, an iconic civic, cultural, retail and entertainment complex, we provided mechanical and electrical design and project managed building services works. The hub comprises a 5000 seat theatre with its striking looks that are matched by outstanding credentials on sustainability as it was awarded a Green Mark Gold rating once completed.

We are also the client’s building services engineer for the Mapletree Business City II, a business park covering 125,000sqm and comprising three blocks of podium and one block of a 30-storey tower.

Urban transit

Our team has been extensively involved in Singapore’s transport network over the years. We acted as consultants to the Singapore Land Transport Authority on the first mass rapid transit line in the region. Since then we’ve been helping the government achieve its ambitious plans of expanding the transport network.

We provided detailed architectural and engineering design, including tunnel boring machine launch and retrieval shafts, for a 6.5km section on the prestigious Eastern Region Line project, which consists of five underground stations and connecting tunnels in challenging ground conditions.

On another notable project, the Downtown Line, we helped with the design and construction of several sections including five stations – Cross Street, Hillview, Cashew, Rochor and Little India. The line improves connectivity for the community in the north-western region of Singapore and saves travel time by up to 30%.

We were also the designer for a 1km extension to the existing North-South Line which serves Singapore’s new financial district in Marina South. The tunnels for the extension are deep and located under the Marina Coastal Expressway road tunnels, which was under construction at the same time.


We have been working closely with clients on all of the recent and upcoming highways developments in Singapore – the Kallang-Paya Lebar, Marina Coastal and North-South expressways.

We provided pre-engineering and traffic studies for the North-South Expressway. We were also the design and build contractors’ designer for three out of the six packages of the new Marina Coastal Expressway, a dual five-lane highway linking the region’s downtown area and eastern suburbs constructed on recently reclaimed land with marine clay as deep as 60m.

For the Kallang-Paya Lebar Expressway, a 12km six-lane highway, we undertook design for contractor Samsung C&T. Our award-winning designs for a complex 3km underground section mitigated the risks of tunnelling in deep soft soils as close as 3m from high-rise housing and underneath a drainage canal.


Mott MacDonald was owner's engineer for Keppel Energy, one of Singapore’s major energy companies, on a large combined cycle gas turbine power plant constructed in on Jurong Island. In addition, we've provided engineering services for the Singapore Power North-South cable tunnels comprising 18km of bored tunnel 40-60m below ground. Key services included advanced engineering design, contract packaging, project management and construction supervision.
