Dam Engineering Discipline Leader

Greg Johnson

The Colliers Engineering & Design engineering professionals have extensive experience in providing all services relating to dam inspection and rehabilitation; geotechnical condition evaluation; engineering analysis; design and construction administration; and hazard classification services for dams. Our professionals also prepare Operations and Maintenance Manuals (O&MM) and Emergency Action plans (EAP) for all types of dams.

Our professionals have an in-depth, working knowledge of Dam Safety Standards that set forth procedures for applications to construct, repair, modify, design, maintain, and inspect dams. Our thorough comprehension of the applicable building and design codes; design guides’ permitting; and the general regulatory process necessary to comply with these standards; ensures our clients of a successful project completion. We maintain prudent and established working relationships with local, county, state, and federal agencies that are critical to maintaining the integrity of a project while keeping the project to schedule and budget.
