Mott MacDonald has had a presence in Spain since the early 1960s, initially supporting landmark projects such as the metro systems in Madrid and Bilbao as well as the country’s first immersed tube tunnel.

Our people have taken lead roles in the highest profile infrastructure and development projects. Working with us you have access to the vast knowledge of internationally recognised engineers, environmentalists, planners, economists, project finance advisors, cost consultants, health specialists, and more.

Our activity rapidly expanded to other major transport developments – including the high-speed rail between Madrid and Barcelona. Since then, we've helped public and private clients deliver energy, water, environment and health projects in Spain and neighbouring countries.

With direct access to the multidisciplinary resources and knowledge of our global company, we offer a substantial advantage to fulfil clients’ diverse and changing requirements. Our local experts look at problems from fresh angles and find opportunities in complexity. They bring together diverse skills and experience to turn obstacles into innovative and sustainable solutions.


We have helped conceive, drive and implement transport solutions around the world. From preparing the business case to developing the infrastructure and ongoing maintenance, our planning, engineering and management services cover the whole project cycle.

We offer clients an optimal solution – local expertise in the project location and resources in Spain that collaborate with teams in the technical office of the client. Multiple projects have been delivered using this approach.

Mott MacDonald has supported clients in the Windsor-Essex Parkway project in Canada, the Northern Line Extension between Charing Cross and Battersea in the United Kingdom, the Third set of Locks of the Panama Canal, the Chesapeake Bay Thimble Shoal Highway Tunnel in the United States and the Brisbane Cross River Rail project in Australia, just to name a few.
