DAMS & LEVEES
Go With The Flow
Dams and levees are critical infrastructure, creating water supply reservoirs, serving as stormwater and flood control structures, supporting hydroelectric power generation, and creating recreation lakes. Many of these structures were constructed in the first half of the 20th century and are now showing signs of age, requiring evaluation, maintenance, and rehabilitation to ensure continued safety and performance.
AMI has a wealth of experience in the evaluation and construction of improvements to existing earthen, rock fill, gravity dams, wing walls, aprons and scour protection structures. We take a measured approach to gather information needed by completing a full review of available project documents, comparison of applicable record drawings and historical design standards. We provide underwater and topside assessments, imaging, geotechnical and hydraulic investigations and material testing. We also provide remedial action recommendations and designs to correct structures that are degraded or do not meet current FERC or other design criteria and safety standards. Our team provides the practical and timely professional services to complete your project.
