U.S. seeks concrete demolition, replacement at 517.8-MW Garrison Dam

The U.S. Army Corps of Engineers seeks bids for demolition and replacement of spillway chute slab and stilling basin concrete as well as joint and subdrain repairs at 517.8-MW Garrison Dam on the Missouri River in North Dakota. A site visit is scheduled April 17 with bids due May 2.

The Corps’ Omaha District awarded a contract last year to Knight Construction and Supply Inc. for flood control tunnel interior repairs and another in 2012 to ESI Contracting Corp. for rehabilitation of drainage systems at Garrison. It also took bids in 2012 to rehabilitate spillway gates at Garrison and at 786-MW Oahe Dam, also on the Missouri.

The district now seeks bids for the concrete work, including removal by hydro-demolition and replacement of about 3,400 square feet of minimum-6-inch-deep concrete on the Garrison Dam spillway. Optional work includes removal and replacement of another 8,200 square feet, repairs to 230 linear feet of cast-in-place pipe, rehabilitation and sealing of nearly 13,000 linear feet of concrete contraction and construction joints, and about 300 square feet of spall and patch repairs by hydro-demolition. The work is valued at $1 million to $2.5 million.
