McNeilus Companies Inc. recently took part in a ceremonial concrete placement event to celebrate the completion of the Wolf Creek Dam Remediation project in Jamestown, Ky.

The project

The Wolf Creek Dam Remediation project includes 1197 piles that are each approximately four feet in diameter and extend 275 feet into bedrock below the foundation of the existing dam’s 4000-foot long embankment.

“The logistical challenges on this project were formidable but, together with the U.S. Army Corps of Engineers and very experienced contractors, we made a great team,” says Doug Pyles, president of Pyles Concrete. “We had 24 S-Series vehicles in our fleet during the project, and the trucks were running 24 hours/day, six days/week, for four years. The vehicles were incredibly reliable; we purchased four new ones when the job began and the rest came from our existing fleet.”

The concrete

In addition, concrete batch plant manufacturer, CON-E-CO, played an important role on the project. Its LO-PRO portable batch plant was located near the site and mixed all of the concrete used for the project.

Wolf Creek Dam is on the Cumberland River in south central Kentucky. The lake’s huge water storage capability provides downstream communities with important flood risk reduction. The dam’s water resources also provide commercial navigation, water supply, water quality, hydropower, and environmental benefits.

Altogether, nearly 300,000 cubic yards of concrete was placed in constructing the entire barrier wall and work platform. Pyles Concrete of Columbia, Ky. used the S-Series trucks, each with an 11-cubic-yard capacity, to deliver and place every single yard.

The Oshkosh S-Series is a leading front- discharge concrete mixer truck. Among its noteworthy features are the McNeilus mixer drum, an Oshkosh transfer case and proprietary axles (developed for military vehicles), an ergonomic cab optimized for visibility and easier troubleshooting, and a patented Load Span Tag Axle (LSTA) for a smoother ride and a 22-inch axle lift.

“Lake Cumberland is the most famous feature of South Central Kentucky, so we were very proud to have been a part of this project,” adds Pyles. “The stakes were pretty high, as well, with Nashville being downstream of the dam and the possibility of the dam failing before the repair work could be finished.”
