IFB_25-040-MC_Addendum_1_ATTACHMENT__B_.pdf

This document is Addendum 1, Attachment "B" for Invitation for Bid (IFB) 25-040-MC for 69 KV Vertical Air Break Replacement Disconnects, issued by a Florida-based utility or government agency. The addendum contains detailed technical drawings and photographs for the replacement of vertical air break disconnects at multiple substations, including Marydia Substation (S01405S & S01405N), BVL Substation (S06405S), and S06407W. The project involves furnishing four (4) outdoor 2000A, 69KV vertical break transformer disconnect switches and associated accessories, with comprehensive technical specifications and site-specific installation diagrams.

The technical documentation provides precise engineering details, including dimensional layouts, connection point specifications, and installation requirements for the disconnect switches. The drawings indicate specific measurements, mounting configurations, and electrical connection details across different substation locations. Photographs of the existing infrastructure are included to provide visual context for the proposed equipment replacements. The technical specifications suggest this is a critical infrastructure upgrade focused on enhancing electrical distribution reliability and maintaining modern substation standards.
