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.




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


Our skills in building and construction economics 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 5,000-seat theater with striking looks that are matched by outstanding credentials on sustainability. 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 1.3 million square feet (125,000 square meters) and comprising three blocks of podium and one block of a 30-story 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 4-mile (6.5-kilometer) section of 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 northwestern region of Singapore and saves travel time by up to 30%.

We were also the designer for a 0.6-mile (1-kilometer) extension to the existing North-South Line that 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 preengineering 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 197 feet (60 meters).

For the Kallang-Paya Lebar Expressway, a 7.5-mile (12-kilometer) six-lane highway, we undertook design for contractor Samsung C&T. Our award-winning designs for a complex 1.9-mile (3-kilometer) underground section mitigated the risks of tunneling in deep soft soils as close as 10 feet (3 meters) 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 on Jurong Island. In addition, we've provided engineering services for the Singapore Power North-South cable tunnels comprising 11 miles (18 kilometers) of bored tunnel 131 to 197 feet (40 to 60 meters) below ground. Key services included advanced engineering design, contract packaging, project management, and construction supervision.
