Mott MacDonald’s operations in Singapore go back over 40 years. Today we’re supporting a range of clients with developments in the rail, road, buildings, infrastructure and energy sectors.


In the energy sector Mott MacDonald is working as the owner's engineer with Keppel Energy, one of the country’s major energy companies, on a large CCGT power plant to be constructed in Singapore's Jurong Island.

Urban transit

Mott MacDonald has been extensively involved in Singapore’s transport network over the years. We were the consultants for Singapore Land Transport Authority on the first mass rapid transit line in Singapore and since then, we have been helping the Singapore government achieve its ambitious plans of expanding the transport network.

Eastern Region Line
We are providing
detailed architectural and engineering design, including tunnel boring machine launch and retrieval shafts for a 6.5km section consisting five underground stations and connecting tunnels in challenging ground conditions.
Downtown Line

We are involved with design and construction of a number of sections of this line including five stations - Cross Street, Hillview, Cashew, Rochor and Little India. The stations are constructed using cut-and-cover techniques whilst the tunnels were excavated using both tunnel boring machines and cut and cover. This line improves connectivity for the community in the northwestern region of Singapore and will save travel time by up to 30%.

North-South Line

Mott MacDonald is the designer for a 1km extension to the existing North-South Line which will serve the new financial district of Singapore in Marina South. The station is built on reclaimed land. The tunnels for the extension are deep and located under the Marina Coastal Expressway road tunnels – which is under construction at the same time.

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.


Mott MacDonald has been involved with all of the recent and upcoming highways in Singapore – the Kallang-Paya Lebar Expressway, Marina Coastal Expressway and North-South Expressway.

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 five packages of the new Marina Coastal Expressway – a dual five lane highway linking the city’s state’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 2km underground section of this six-lane highway mitigated the risks of tunnelling in deep soft soils as close as 3m from high-rise housing and underneath a drainage canal.

Our building and construction economics skills are well represented on major projects such as the Star Vista, a S$976 million civic, cultural, business, retail and entertainment complex. We've been providing mechanical and electrical design and project managing building services works.

The hub’s striking looks will be matched by outstanding credentials on sustainability having achieved BCA Green Mark Gold rating.

Additionally, Mott MacDonald also worked as part of a technical advisory team on a PPP accommodation project – the Nanyang Technological University’s student residency facility providing dormitories for 6,600 students.
