The U.S. Army Corps of Engineers has awarded a US$559,000 contract to Emagineered Solutions Inc. for remedial waterstop repairs in the upstream monolith joints at the 494.3-MW Big Bend hydroelectric project.
The Corps’ Omaha District most recently solicited bids for the work in May, which include construction management and installations services for drilling and installing new waterstops in upstream monolith joints 3/4 and 5/6 of the Big Bend powerhouse.
Per the tender, Emagineered Solutions 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.
HydroWorld.com reported that 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.
Emagineered Solutions was awarded a comtract for drilling and grouting services at the 2,160-MW John Day hydropower plant in Oregon earlier this year.
