There are over 91,000 dams across the U.S., many of which have been classified as high-hazard structures with an estimated rehabilitation cost of nearly $20 billion. Locks and dams along the the nation’s inland waterway network, owned and operated by the U.S. Army Corps. of Engineers, are well past their 50-year design life. The cost to rehabilitate federal dams is estimated to be more than $25 billion.
As a top ten builder of dams, reservoirs, and water supply systems, Shimmick is posed to meet this growing need. Shimmick’s solutions enable reliable water supply, generate hydroelectric power, control flooding, and ensure water availability. Our work protects communities from flood damage and safeguards lives and property.
Shimmick and its legacy companies have a long history of delivering locks and dams, flood control, levees, fish screens, stream diversions, and pump stations for federal, state and municipal clients. Shimmick self-performs a large majority of work, including mechanical, electrical and plumbing scopes for water resources projects.
For example, at the LaGrange Lock and Dam in Illinois, USACE chose Shimmick to perform a major rehabilitation of the more than 80-year-old dam along one of the main inland waterways where barges transport nearly 830 million tons of the nation’s goods every year. Additionally, we recently completed the Rapid Disaster Infrastructure and Levee Repair for USACE, building more than five miles of levees in Missouri to protect the area from flooding. A Shimmick-led joint venture also replaced an aging lock and dam and constructed the new Olmsted Dam on the Ohio River, where according to USACE, more commerce traverses than any other location on the entire U.S. inland waterways. With the Olmsted lock and dam replacement, economic net benefits to the nation are estimated to be more than $640 million annually.
