61--Electric brake motors, flexible couplings, molded case circuit breakers, full voltage reversing starters, and control transformers for Chickamauga Lock.

Solicitation W912P5-13-T-0055, issued by the Department of Defense through the US Army Corps of Engineers Nashville District, is a total small business set-aside contract for the procurement of critical industrial electrical components for the Chickamauga Lock in Chattanooga, Tennessee. The scope of work involves the acquisition of electric brake motors for culvert and miter gates, flexible couplings, full voltage reversing starters, and control transformers. The procurement includes specific technical requirements for motor replacement, referencing detailed power curve design data, wiring diagrams, and mechanical specifications for shaft seals and reduction ratios to ensure compatibility with existing gate and valve operating machinery. A key requirement of the contract is the procurement of Cutler Hammer Molded Case Circuit Breakers, which were designated as a sole-source requirement to ensure a precise bolt pattern match with existing motor control center buckets. This specification was mandated to prevent expensive modifications and avoid disruptions to navigation industry operations. The procurement process, which concluded with a response deadline of August 30, 2013, required strict adherence to submittal procedures and low-voltage motor standards to maintain the operational integrity of the lock's infrastructure.
