Dams are unique and diverse structures. They are a part of our American History and many of the most famous dams – Hoover, Grand Coulee, Glen Canyon, and Flaming Gorge Dam – are engineering marvels visited by thousands of people each year. Almost everyone knows what a dam does; it impounds water. However, most people know very little else about dams, including why they fail. Many factors can contribute to the failure of a dam including age, flooding, maintenance, construction flaws, foundation issues, earthquakes, seepage, and even design flaws. McMahon’s engineers perform all permitting, final design, and construction inspection phase services required to replace the existing structure. If you have a dam to maintain or to design, our specialty knowledge of this water transportation control device can be put to service for you.
