About this file

This document is an amendment to a solicitation for replacement variable frequency drives (VFDs) for a dredge. The U.S. Army Corps of Engineers Engineering District St Paul issued the solicitation and is seeking VFDs that can be used as replacements in existing VFD cabinets on the dredge Goetz. The amendment provides answers to five questions from vendors, including cabinet dimensions, electrical schematics and motor nameplate information provided in a previous amendment, as well as specifications for dynamic braking resistors located in the VFD cabinets. All other terms and conditions of the solicitation remain unchanged. The maximum ratings of the existing VFDs can be used to size the new replacement VFDs.
