The U.S. Army Corps of Engineers has awarded two contracts for lock rehabilitation at Olmsted Dam on the Ohio River in Kentucky.
The first contract, worth $11.8 million, was awarded to C.J. Mahan Construction Company LLC of Ohio, for a major lock rehab project. The twin 1,200-foot-long locks are in need of rehabilitation to return them to reliable functional condition, the Corps says. This contract includes dewatering two lock chambers, cleaning of miter gates and culvert valves, extension of two maintenance bulkhead reinforced concrete sills, replacement of air bubbler and grease lines in the lock chambers along with solenoid valves on the bubbler system, repair of culvert valve latching bars and addition of a culvert valve support beam. Also included is remanufacture of eight miter gate and eight culvert valve cylinders and fabrication of two new miter gate and two new culvert valve cylinders. Also included is replacement of lock control systems.
A second contract, worth $674,000, was awarded in February to T&T Construction Enterprises LLC of Leitchfield, Ky., for minor lock rehab. Specific details of the work to be performed under this contract were not disclosed.
Olmsted Dam is part of the Corps' Locks and Dam 52 and 53 Replacement Project, known as Olmsted Locks and Dam, under construction between Illinois and Kentucky about 17 miles upstream from the confluence of the Ohio and Mississippi rivers. The Olmsted Locks and Dam project is to reduce tow and barge delays through the busiest stretch of river in America's inland waterways.
The project received $2.8 billion in funding as part of 2013 legislation that ended the federal government shutdown. Although the Corps dam has no hydropower, American River Power II LLC holds a Federal Energy Regulatory Commission preliminary permit to study building a 63-MW hydro project (No. 14325) at the site.
