About this file
This document contains drawings for a project by the Texas Department of Criminal Justice (TDCJ) to replace a transformer at the Estelle Unit in Huntsville, Texas. The drawings show the demolition plan for the existing transformer and the equipment installation plan for the new 750 KVA, 12.47 kV-480/277 V, 3-phase power transformer. The project will involve disconnecting and re-routing the existing 12.47 kV primary wiring and 480/277 V secondary wiring to the new transformer location. The project is scheduled for construction on May 8, 2023.
The related state and local contract opportunity indicates that TDCJ is requesting bids to procure and install the replacement transformer. The project will be located in Walker County, Texas, and the city of Houston. No other details are provided regarding pricing, funding sources, set-asides, or the incumbent contractor.
