This set of construction drawings documents the HVAC and plumbing upgrade project for Lamar Reese Elementary School located at 1215 Lily Pond Road, Albany, Georgia 31701. The project involves the comprehensive replacement of heating, air conditioning, and plumbing systems throughout the facility, with work organized into six construction phases to minimize disruption to ongoing school operations. The scope includes demolition and removal of existing wall-hung heat pumps (WHHP), rooftop heat pump units (RTU), fan coil units (FCU), and associated refrigerant piping, followed by installation of new HVAC equipment including 35 wall-hung heat pumps, multiple rooftop units, ductless fan coil units, outside air units, and exhaust fans. The project also requires extensive ductwork modifications, condensate drain piping installations, and architectural modifications including new ceiling grid work and chase walls to conceal mechanical systems. The contractor is responsible for R-22 refrigerant recovery from all removed equipment, with recovered cylinders to be returned to the owner for processing. Construction sequencing allows for temporary modular classroom units to house displaced students, with a maximum of six classrooms relocated per phase.

The drawings specify detailed mechanical schedules and performance requirements for all HVAC components, including supply and exhaust fan specifications with defined CFM ratings, static pressure requirements, and motor horsepower specifications. Installation details address critical construction requirements such as condensate drain trap configurations, refrigerant piping routing through exterior walls, fire damper installations at wall and floor penetrations, and bi-polar ionization unit integration into new equipment. The project includes substantial ductwork fabrication with insulation requirements for exterior rooftop ductwork and detailed lintel installations for new duct penetrations through existing walls. Plumbing components are scheduled on separate drawings (P101-P103), and electrical work for power circuits and controls is coordinated through electrical drawings with mechanical installation responsibilities clearly delineated. The construction documents establish phased work completion requirements with attention to maintaining occupied building access, protecting existing structures, and restoring affected areas upon completion of each phase.
