This is a comprehensive set of mechanical and plumbing design drawings for the Morningside Elementary School HVAC and Plumbing Upgrades project located at 120 Sunset Lane, Albany, Georgia 31705 (GA DOE ID #2058). The project scope encompasses the complete replacement and upgrade of heating, ventilation, air conditioning, and plumbing systems throughout the facility. The work includes removal and installation of wall-hung heat pumps (20 units), rooftop units (8 units), exhaust fans (12 units), ceiling heaters (10 units), ductless indoor units (8 units), heat recovery units, and associated ductwork, piping, and controls. The project is organized into five construction phases to minimize disruption to school operations, with provisions for relocating up to six classrooms per phase to temporary modular units. The design includes new equipment support platforms, concrete pads, roof curbs, and architectural modifications such as new ceiling chases and bulkheads to conceal ductwork. All existing R-22 refrigerant must be recovered by the mechanical contractor during demolition for owner processing.

The drawings specify equipment from Carrier as the basis of design, including variable refrigerant flow (VRF) systems, 100% outside air handling units with DX cooling coils, and ductless split-system heat pumps with R-410A refrigerant. The project requires installation of duct insulation, condensate drainage systems with traps and supports, fire and smoke dampers, motorized dampers, and building automation system integration. Specific details are provided for equipment installation, including wall-mounted units requiring integral bi-polar ionization units for indoor air quality, duct penetrations through walls and floors with sleeves and lintels, and roof-mounted equipment with curb adapters and concrete pads. The contractor must coordinate with existing building systems, field verify all dimensions and conditions, and provide protective measures for occupied areas during construction. The drawings indicate requirements for accessibility, maintenance clearances, and compliance with manufacturer specifications for refrigerant piping, condensate drainage, and electrical connections.
