From the smallest to the largest, most complex projects, all tunnels have their own individual challenges. Hatch Mott MacDonald meets those challenges by combining knowledge of the ground with design and construction technologies that are right for the job. Through years of serving clients according to these simple but essential principles, we have delivered some of the most challenging tunneling projects ever undertaken. We've won awards for innovation and engineering excellence, and in several circumstances, accomplished what others said could not be done.

Through our founders' involvement in the development of London’s underground road and rail systems over a century ago, and their work on Toronto’s subway system more than 50 years ago, Hatch Mott MacDonald has an established history of tunneling expertise. Our association with these organizations continues today - a testimonial to the quality of our work. Hatch Mott MacDonald has engineered more than 1,600 miles of tunnels worldwide including world class projects such as the Channel Tunnel. The firm is equally proud of our engineering accomplishments across North America, including projects in: Los Angeles; Phoenix; San Diego; San Jose; San Francisco; Sacramento; Seattle; Atlanta; Buffalo; Boston; Cleveland; Connecticut; Florida; Kentucky; Minneapolis; Michigan; New Jersey; New York; Philadelphia; Pittsburgh; Washington DC; West Virginia; Toronto; Calgary; and Vancouver. We offer a proven track record of innovation, the ability to solve tough problems, and a willingness to listen. That’s how Hatch Mott MacDonald makes a difference.

We tailor our tunnel engineering knowledge to the issues that our clients face. While the ground may not know whether water, vehicles, or trains are being conveyed through a tunnel, our clients do. We offer our tunnel engineering services within a client-based focus.
