DAMS & LEVEES

Go With The Flow

Dams and levees are important infrastructure, creating water supply reservoirs, serving as storm water and flood control structures, hydroelectric generating facilities and creating recreation lakes. Many were constructed in the first half of the 20th century and are showing their age.

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.

AMI understands environmental regulations and how they affect each phase of your project. We know that securing a permit that is tailored to your project is essential to maintain your operating schedule and maximize profit. We have experience monitoring in-field conditions and proactively working ahead to prevent costly delays. We have been there before and can help you navigate through the regulatory requirements and mitigate your project risks. AMI offers complete permitting services for all aspects of the marine and environmental industry. Our knowledge of the permitting systems includes the DNR, EPA, ACOE, Fish and Wildlife, SHPO, submerged land leases and open water mitigation.

Included in our inspection arsenal is a complete line of underwater and topside imaging equipment. Our underwater imaging includes single and multi-beam bathymetric surveys, processed with HYPACK software to produce complete underwater mapping for general design, dredge planning and payment. AMI performs side scan sonar and sector scan imaging to create underwater pictures of structures, debris fields, and impact damage. The sonar can also be utilized to find and salvage sunken objects. Sub-bottom profiling and magnetometer surveys are two other water-based services AMI can supply. Topside, AMI can utilize laser scanning to create detailed images and layouts of structures.
