Mott MacDonald has been operating in Thailand since 1974, working on a diverse range of projects in energy, transport, advisory and international development. Our Bangkok office has also contributed to health and education initiatives in the region since the early 2000s.

Our Bangkok office has become a centre of technical excellence. We positively contribute to society with provision of thought leadership on some of the world’s most pressing issues, including tackling climate change through energy decarbonisation and advancements in infrastructure, coupled with working to strengthen the health and education system. Our digital innovation and focus underpins all of our work

Rom Rakpatapeesuwan

Country manager

We have over 90 staff engaged in planning, developing and delivering outcomes for our clients and communities. Our team works closely with clients and our other offices in Asia to provide an integrated service that is second to none.


We’re one of the industry's leading advisors to private developers and banks for a variety of low carbon and renewable energy developments. Our teams support local and international projects across Asia.

With expertise spanning the full project lifecycle, our services include meteorological station and met mast campaign management, plant layout optimisation, flood protection design, technology selection and yield optimisation, procurement, detailed design review, commissioning and operational performance review, and performance-based reassessment of future plant production.

Renewable energy

Having supported most solar and wind power operating capacity developed in Thailand and South East Asia to date we fully understand the challenges and opportunities for solar and wind power projects. We regularly publish and present leading-edge papers to share insights.

Working with our network of offices, our experts provide robust and forward-looking technical advice, supporting over 18GW of solar projects and 20GW of wind projects across Asia Pacific.

Moata, our digital twin platform, hosts solutions that use the power of data to solve today’s most pressing problems. Moata Smart Energy offers a suite of solutions that help our clients solve challenges associated with intermittent renewables.

Low carbon energy

For thermal power generation, we’ve provided technical advisory services to owners, lenders and investors on gas fired, biomass and energy from waste projects throughout East Asia. We’re familiar with the latest technological developments at all scales of power plants, from a few MWs up to several 1000MWs. Combining our expertise in thermodynamic modelling and simulation with evaluation methodologies, we assist in developing efficient and cost-effective thermal power stations that provide reliable power generation.


Mott MacDonald has worked on a number of city-shaping projects. In a consortium with Epsilon and Norconsult Civil Engineering, we undertook the feasibility study and preliminary and detailed design of the Bangkok Industrial Ring Road bridge for the Department of Rural Roads, Bangkok. The project forms part of the Industrial Ring Road, connecting industrial areas in Samut Prakarn with the Port of Bangkok.

We helped widen a four-lane highway on the Greater Mekong Subregion East-West Economic Corridor and completed detailed engineering design of Tak-Mae Sod highway for the Department of Highways. On behalf of the World Bank, we also developed a public private partnership procedure for the Thailand Highways Management project.

On major mass transit works, our experience ranges from feasibility to project management and construction supervision. We carried out feasibility studies on the Yellow, Brown and Pink mass transit lines for the Office of Transport and Traffic Policy and Planning. As well as tender designs for the Mass Rapid Transit Authority of Thailand Blueline extension, we were the project management consultant for the first underground mass rapid transit system in Thailand. We are providing project management and construction supervision on the Orange Line east section.


Mott MacDonald is contributing to the realisation of the UN Sustainable Development Goals and Bangkok’s future-focused vision.

We offer expertise in smart city technologies, sustainable urban development, flood protection, and transport planning. We bring together local and international expertise in project management, data analytics, urban planning, transportation, water management and other disciplines to service our client’s needs.

We are engaged as delivery partner for the Global Future Cities Programme which is focusing on building resilience and enabling smart transport in Thailand.

International development

The increase in life expectancy displays how lives have been impacted. Advances in medicine and technology mean more people are accessing healthcare services and for longer, what can be treated is increasing, and how and where this treatment can be provided is ever changing. This success brings challenges for a country's health system as it must respond to these changes and meet the needs of its citizens in a way that is sustainable.

We recognise these evolving challenges and work with governments and healthcare providers to develop specific solutions to meet future needs. We provide support across the entire spectrum of healthcare from design, planning and delivery, to evaluation and monitoring. This offering extends into social infrastructure, the built environment, water and environmental planning.

Our Fleming Fund South East Asia regional team is part of the £265M UK aid programme supporting up to 24 countries in tackling antimicrobial resistance (AMR). We work closely with governments to ensure programming contributes to national health system strengthening and prioritises investment in public sector laboratories and surveillance systems.

Our education assessment team was set up by our experts in Cambridge Education in 2002 to support education reform around the country. In Bangkok, we have repeatedly completed large cycles of school assessments. For example, the evaluation reports from 105 school assessments across seven provinces were rigorously quality checked by the team before submission to the Office for National Education Standards and Quality Assessment, the Thai government department responsible for standards in education.
