The Shaw Group Inc. is one of five firms that will compete for $225 million worth of U.S. Army Corps of Engineers projects under a contract to provide nationwide environmental and restoration services for the agency’s Louisville District.

Shaw will investigate what environmental remediation is needed, restore ecosystems, and provide environmental dredging, operation and maintenance, and emergency response activities to support the Corps’ projects.

The contract includes a two-year base period and four two-year options. The undisclosed value of the contract was included in Shaw’s Environmental & Infrastructure segment’s backlog of unfilled orders in the first quarter of fiscal year 2012.
