About this file

This document is a Bid Addendum for the Armed Forces Retirement Home Gulfport Generators Project (Project No. AFRH-041), dated 07.31.25. The addendum comprehensively revises multiple drawing and specification sections related to generator replacement, including electrical plans, one-line diagrams, generator sets (diesel, gas, and propane), and associated equipment. Key modifications include updates to generator enclosure footprints, electrical plans, load bank layouts, generator ratings, alarm lists, and specifications for generator types and controls.

The addendum includes attachments covering eight drawing sheets (from G001 to P101) and thirteen specification sections, with notable changes to specifications for diesel, gas, and propane engine-driven generator sets, medium voltage switchgear, and load bank requirements. Specific revisions include updating generator ratings, removing certain requirements like relative humidity specifications, clarifying test and inspection scopes, and refining technical details for generator installation and performance. The comprehensive nature of the addendum suggests significant technical refinements to the original generator replacement project specifications.
