About this file
This document appears to be a set of electrical drawings and specifications for the Repair Well #10 project at Keesler Air Force Base, Mississippi under Solicitation Number FA301024R0013.
The key details include:
- The project involves demolishing the existing generator, automatic transfer switch (ATS), well pump, and chlorine pump, and replacing them with new equipment. It also requires verifying the existing diesel tank can support the new generator.
- The new generator must be a 150kW, 480V, 3-phase standby generator capable of handling the required electrical loads. The new ATS must be a 480V, 200A, 3-phase unit with delayed transition and bypass isolation.
- The contractor must provide all necessary grounding, bonding, and accessories for a complete and functional system. The system must comply with relevant Air Force and UFC requirements.
- The contractor is required to provide redline as-built drawings with updated conduit, conductor, and disconnect fuse sizes and corrected diagram layout.
The federal contract opportunity associated with these drawings indicates it is a small business set-aside with an estimated project value between $250,000 and $500,000. An organized site visit is scheduled for August 12, 2024 and proposals are due at a future date.
