Inspection, repair, and construction services on dams have been part of J.F. Brennan Company’s core business segment of marine construction since its founding. Over the years, we have teamed with several government, utility, paper mill, and municipal entities to inspect, repair, and build water-based infrastructure. We have worked extensively throughout the Midwest on dam structures of all types. This includes all 29 Upper Mississippi River lock and dam systems, numerous hydro powered dams, and many non-powered dam structures. Brennan has the flexibility to perform small repairs, or work on capital projects that require large equipment and expert personnel.
