Our 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, energy and water sectors.

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 features leisure, retail, hotel and airport operations facilities.

Singapore’s Indian heritage is celebrated by a 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 the transport network in the region over the years. We acted as consultants to the Singapore Land Transport Authority on the first mass rapid transit line. We’ve been helping the government achieve ambitious expansion plans.

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

On 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 and saves travel time by up to 30%.

We were the designer for a 1km extension to the existing North-South Line which serves Singapore’s 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.


We were 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. We've provided engineering services for the Singapore Power North-South cable tunnels comprising 18km of bored tunnel 40-60m. Key services included advanced engineering design, contract packaging, project management and construction supervision.


Our water team can guide you through the water sector’s key challenges – ageing infrastructure, population growth, water scarcity and climate change. Constantly searching for the opportunity to add value, we provide innovative, sustainable solutions for water supply, wastewater recycling, and water management.

From specialist utility and drainage design – including the complex relocation of water and sewer networks, to hydrology and flood risk management, to advisory, asset management and the maintenance of operational facilities – our skills are wide-ranging.

Examples of major water infrastructure projects we’re working on include Changi’s water reclamation plant upgrade in Singapore and Palembang’s wastewater scheme in Indonesia. We’re also supporting the development of several IFI-funded water projects.

With a focus on delivering projects digitally by default, we are using building information modelling (BIM) to unlock efficiencies, and our cloud-based analytics and visualisation service – MOATA – provides real-time insights on asset performance.
