About this file
This document package includes drawings and specifications for an electrical system upgrade project. The contractor will be required to install a new 1150 KVA outdoor transformer to feed the 480V switchgear in Sub-basement 1 of the facility. Additionally, the contractor will correct wiring deficiencies for CAT Scan rooms and move the electrical feeds for several air handlers and associated chilled water pumps and controls to emergency power circuits. The project drawings provide details on the new transformer installation, medium voltage single line diagram, and floor plans to guide the electrical system upgrade work. The related pre-solicitation lists the Department of Veterans Affairs as the contracting agency and provides additional context that the intent is to address deficiencies and improve the 480V electrical system at the Louisville, KY location.
