This is a technical plan document for the West Municipal Garage Beam Replacement project located in Green Bay, Wisconsin, prepared by Berners-Schober Associates, Inc. The project involves HVAC system modifications including the demolition and replacement of an existing power roof ventilator (PRV), ductwork reconfiguration, and associated structural work. Key deliverables include removal of existing ducts and dampers to accommodate beam replacement, installation of new ductwork with a Greenheck GB-220 exhaust fan rated at 4,000 CFM with 0.50 HP, roof penetration work with an 18-inch tall insulated curb, masonry wall modifications, and electrical reconnection work. The plan specifies coordination requirements with multiple trades including structural, general contractor, firestopping, and roofing contractors. The project is identified as an alternate bid item with control damper or backdraft damper provisions dependent on existing fan configurations.

The project requires coordination of fire-rated wall penetrations, confirmation of existing motor voltage specifications in the field, and compliance with firestopping requirements for multiple penetrations in the same opening. Work includes patching and restoration by the general trade, with the fan schedule noting provisions for disconnect switches, control dampers, and sheave changes following system balancing. The bid document references standard construction specifications including selective demolition, unit masonry work, metal fabrications, roof patching, and joint sealants. The project was issued for owner review on April 11, 2023, with a bid document date of May 9, 2023. Additional contractual documentation referenced includes AIA Document A105-2017 for the agreement form and insurance requirements per Exhibit A.
