About this file
These documents are technical plans for the rehabilitation of a tow haulage high speed gearbox and limit switch at the Nickajack Auxiliary Lock in Hardin County, Tennessee, prepared by the U.S. Army Corps of Engineers Nashville District. The project (Contract W912P5-25-Q-A032) involves replacing multiple components including bearing bushings, bearings, oil seals, and stub shafts, with specific requirements that shafts must be replaced "In-Kind" to original dimensions. The technical drawings specify a NEMA 4X limit switch enclosure to be provided by the contractor, and include detailed part lists and dimensional specifications for the gearbox rehabilitation, with a projected completion date of June 2025.
The associated federal contract opportunity is a small business set-aside solicitation for commercial and industrial machinery equipment repair and maintenance (NAICS 811310). A mandatory site visit is scheduled for July 16, 2025, at 10:30 AM CST, with strict security access requirements for both U.S. citizens and foreign nationals. Interested contractors must be registered in the System for Award Management (SAM) and submit appropriate security access forms. The primary point of contact is Jori Cox, and potential bidders are required to provide company details, CAGE/UEI numbers, and contact information when expressing interest in the project.
