About this file
This is an addendum to specifications and drawings for the 182nd Airlift Wing, Peoria Air National Guard Building 632 Repair of Fire Suppression and Hangar Doors contract, issued August 7, 2026.
The addendum makes multiple specification revisions across several sections. In Section 05 12 00, two ASTM references (F1136/F1136M and F2833) are deleted. Section 05 50 13 undergoes substantial revisions, including deletion of seven welding and aluminum-related standards (AA DAF45, AWS D1.2/D1.2M, ASTM B26/B26M, B108/B108M, B209/B209M, B221, B221M), complete removal of welder qualification requirements, deletion of aluminum alloy product specifications, removal of aluminum surface treatment paragraphs, and deletion of the second sentence in the Dissimilar Metals section. Similar aluminum and welding-related deletions apply to Section 05 50 33. Section 08 34 16.20 removes requirements for belt/wire rope system specifications and backup door operation procedures. Section 26 32 15 changes the engine-generator frequency parameter from 50 Hz to 60 Hz. New requirements are added to Section 26 36 23 for a camlock docking station assembly supporting full-capacity portable load bank testing at 1200A, 480V, 3-phase, with NEMA 4X stainless steel pad-mounted enclosure, shunt trip circuit breaker, female camlock configuration, and specified outlet configurations. Section 28 31 70 removes audible notification appliance and horn requirements while revising visual notification appliances to reference "Fire" instead of "Alert." Revised drawings effective August 8, 2026 accompany this addendum covering fire alarm, electrical, and related building systems.
