Dam and Levee Engineering

Dams and related features serve a critical role in providing water supply, hydropower, flood control, recreation, and other benefits. Given their importance, we have a dedicated team of experts focused exclusively on dam, levee, and water resource projects throughout the United States. This group represents over 30 percent of our business and continues to grow, in part a result of several of our projects winning prestigious awards from peers and professional societies.

We provide a broad range of services including dam safety inspections, engineering analyses, hydraulic modeling, project planning, design, and construction oversight. We have met our clients’ needs with all types of dams, including earthen, concrete, and roller-compacted concrete structures.
