This is a mechanical floor plan drawing for an HVAC duct work remodel project at 50 Monroe Street in Medford, Oregon, prepared for the Maslow Building. The drawing, dated November 9, 2021, with project number 21-1180, illustrates the mechanical systems layout for the facility's first floor, which contains multiple office spaces, conference rooms, common areas, storage rooms, and support facilities. The plan shows the routing of supply ducts, return ducts, and exhaust systems serving four air handling units (AHU-1 through AHU-4), along with equipment locations, duct sizes ranging from 4 to 28 inches, and connections to existing and new ductwork. The drawing indicates provisions for thermostat locations, equipment flues, and various air distribution components throughout the 11 rooms and corridors depicted on the floor plan. The document is marked as preliminary and explicitly states it shall not be used for construction bidding, recordation, conveyance, or permit issuance.

The scope includes general notes requiring contractors to fire-caulk all duct and pipe penetrations through fire-rated walls and floors, coordinate with other trades, provide flexible duct transitions for mechanical equipment, and verify all field dimensions and routing before installation. The project requires cleaning and reuse of existing equipment and grilles where feasible, replacement of insulation to current code requirements, and a final system balance report with airflow volume dampers in all supply, return, and exhaust branches. Keyed notes specify work on individual duct runs, equipment flue vents routed to a common 10-inch flue vent, and installation of a new Greenheck exhaust fan, while AHU-4 and AC-1 are to remain unmodified. The plan emphasizes field verification and coordination with the general contractor and owner's representative regarding any major changes requiring cost adjustments during the bidding phase.
