Y--FY11 Trail Creek Sea Lamprey Barrier, Michigan City, IN

Contract W911XK-11-C-0004, solicited under number W911XK-11-B-0001, is a total small business set-aside project managed by the Department of Defense through the Detroit District of the U.S. Army Corps of Engineers. The project involves the construction of a steel sea lamprey barrier and fish way in Trail Creek, located in Michigan City, LaPorte County, Indiana. With an estimated cost between 500,000 and 1,000,000 dollars and a performance period of 210 calendar days, the scope of work includes clearing and grubbing, erosion control, tree removal, and the construction of an access road using excavation, fill, and aggregate. Additional requirements include the placement of a stay-in-place cofferdam, barrier SSP, geo-textile, riprap, and reinforced concrete for the fish way floor and walls. The contractor is responsible for fabricating and installing fish way appurtenances such as baffles, fish screens, an upstream gate, and grating, as well as installing chain link fencing and warning signs. Technical specifications emphasize that site access is restricted to the east side of the creek. The project is subject to a temporary in-stream work waiver from the Division of Fish and Wildlife, permitting construction from July 1 through October 31, 2011, to ensure fish stocking events are not impacted. The procurement process included a sealed bid solicitation with a deadline of May 5, 2011, and subsequent technical clarifications regarding steel sheet piling, pile testing, and design elevations.
