The U.S. Army Corps of Engineers seeks bids for remedial waterstop repairs in upstream monolith joints at the 494.3-MW Big Bend hydroelectric project on the Missouri River in South Dakota. Bids are due June 6.
The Corps took bids in 2013 for spillway dike bank stabilization at Old Fort Thompson at the Big Bend project, which began operation in 1952 near Fort Thompson, S.D. The agency awarded contracts in 2012 to J.F. Brennan Co. Inc. for rehabilitation of spillway gates and to Brunow Contracting LLC for dam embankment repairs at Big Bend. The Corps also took bids in 2010 to replace waterstop materials and bladders at Big Bend.
The Corps’ Omaha District now seeks construction management and installation service for drilling and installing new waterstops in upstream monolith joints 3/4 and 5/6 of the Big Bend powerhouse. The contractor is to coordinate with the waterstop system developer and provide concrete drilling, video inspection and installation services to replace the existing system with a new joint system to prevent water from flowing on or under the generator equipment floor.
The work is valued at $500,000 to $1 million. The winning contractor must begin work within 10 days after notice to proceed, and must complete the job in 150 days.
