Attachment - Supporting Drawing and Graphics 01-31-26.pdf

This document is a supporting drawing and graphics file that contains technical illustrations and photographs of HVAC equipment to be replaced under a federal contract.

The document depicts overhead, ground-level, and western-facing views of equipment located at a facility, with an annotated floor plan identifying two primary work areas. The overhead annotated view specifies work requirements for removing and replacing an in-kind air handling unit and a condensing unit. For the air handling unit replacement, the government will isolate utilities, while the contractor must reconfigure or replace plumbed utilities to make connections, modify physical ductwork connections as needed, and replace surface-mounted electrical service to the equipment connection point. The government assumes responsibility for repairs or modifications to roof curbs to accommodate new equipment and will match existing rolled asphalt. For condensing unit replacement, the government will perform refrigerant evacuation and handle electrical isolation and service element replacement up to and including disconnect points; the contractor is responsible for line set reuse (with government providing no warranty on condition and leaks being contractor responsibility). The document includes photographic evidence of existing equipment, including two Haakon Industries air handling units with visible nameplates and specifications, three rusted electrical enclosures/disconnects to be replaced by the government, and a Trane condensing unit model TTA180E40SAA with detailed technical specifications including R410A refrigerant, 460V 3PH 60Hz rating, and 1 HP capacity.
