The U.S. Army Corps of Engineers has awarded a $25.7 million contract to OCCI Inc. to repair tainter gates at Harlan County Dam in Nebraska.
The Corps plans rehabilitation of two to three spillway tainter gates at Harlan County Dam, a rolled-earth embankment and concrete gravity dam built for flood control and irrigation on the Republican River in the 1950s. The dam, which impounds the second largest lake in Nebraska, includes a controlled spillway regulated by 18 tainter gates, nine sluice gates, and two irrigation outlets.
OCCI of Fulton, Mo., is to strengthen structural steel components, replace trunnions and bearings with new components, replace tainter gate chains, repair or replace electrical systems, and blast and paint gates.
The Corps’ Kansas City District took bids for the work in June. It also took bids in August to replace electrical wiring at Harlan County Dam. It took bids in 2013 to fabricate and install stoplogs for spillway repair work.
