The U.S. Army Corps of Engineers is soliciting quotes for commercial services to perform a comprehensive diagnostic of a Variable Frequency Drive (VFD) and its repair or replacement, followed by a full operational load test of the electric hoist motor, final system tuning, integration testing, and safety certification to restore elevator service. The work will be performed in Indiana, and contractors must be licensed elevator repair contractors in that state, with personnel trained and certified for fall protection per USACE EM 385-1-1. This requirement is not set aside for small business, and all responsible sources may submit a quote. Interested contractors must be registered in SAM at the time of quote submission and submit quotes electronically via the PIEE system.
