What We Do

Structures &
Building Systems

The vast experience and capabilities of our Structures and Building Systems division will help your projects to a successful completion. We’ll assist from preliminary conceptual design through final construction assistance and operation, supporting as needed in each step along the way.

We thrive in the challenging conditions that come with the variety of our projects’ locations, both within the United States and internationally: complex architectural systems, heavy design loads (high seismic, coastal wind regions, heavy snow accumulations) and building code systems compliance.

Whether we are a single-discipline consultant or part of your overall McMahon team, we look to establish the trust of meeting your expectations, both for this project and beyond.
