Attach I - Addendum 1 - Summary.docx

This is an Addendum 1 Summary document that outlines updated drawings and specifications for the Upgrade Campus Electrical Systems project (Project Number 610A4-23-101) at Ft. Wayne, Northern VA Healthcare System. The document provides detailed modifications to construction drawings and specifications resulting from the addendum issuance, which was posted under Amendment 0008 to the solicitation.

The drawing modifications affect multiple electrical and architectural sheets, including updates to general notes, stair details, and automatic transfer switch (ATS) equipment information across sheets AE401, E202, E204, E206, E208, E210, E502, ED101, ED101A, and EP101D. Specific changes include marking ATS-6 and ATS-10 as demolition items on certain sheets while showing new ATS-6 and ATS-10 equipment on others, revising the ATS-10 feeder configuration, and adding information related to an associated boiler project. Specification modifications address Unit Masonry (Section 04 20 00) to include face brick, introduce an entirely new Insulated Metal Wall Panels specification (Section 07 42 13), and update the Ethylene Propylene Diene Monomer Roofing specification (Section 07 53 23) to specify 60-mil thickness. These modifications support the core project scope of providing a new electrical service upgrade including demolition of existing equipment, a 6,600 square foot addition to Building 1 for primary switchgear, three 600 kW standby generators, and three new unit substations for the Department of Veterans Affairs facility.
