This comprehensive set of mechanical, plumbing, and electrical drawings represents the design documents for an HVAC and plumbing upgrade project at International Studies Elementary School located at 2237 Cutts Drive, Albany, Georgia (Project Number 5056, GA DOE ID 5056). The project scope encompasses the complete replacement of the heating and air conditioning systems and plumbing fixtures throughout the facility. The work is organized into four construction phases designed to minimize disruption to school operations, with temporary modular classroom buildings (maximum eight classrooms per phase) provided by the contractor to maintain educational continuity. The mechanical scope includes removal and replacement of 30 wall-hung heat pump units, installation of two Variable Refrigerant Flow (VRF) systems with multiple indoor units (cassettes and ducted units), replacement of ceiling heaters, exhaust fans, packaged terminal heat pumps, and associated ductwork and piping. The plumbing scope requires replacement of water closets, urinals, lavatories, sinks, water coolers, and related fixtures with specified models including sensor-activated and metering devices. The electrical work involves demolition and installation of systems to support the new mechanical and plumbing equipment, with coordination required between all trades throughout construction.

The drawings indicate a phased approach with general notes requiring contractors to field-verify existing conditions, coordinate with the school owner regarding equipment placement and temporary wall installation, maintain access to exit doors and restrooms at all times, protect existing building elements from damage, and recover R-22 refrigerant from all existing equipment scheduled for demolition. The contractor is responsible for providing all labor, tools, recovery equipment, and refrigerant recovery cylinders, with filled cylinders to be returned to the owner for processing. The design incorporates 6-foot chainlink fencing around equipment yards with 3-foot service gates, concrete equipment pads for rooftop units, and integration of existing ductwork where reusable. The mechanical systems utilize R-410a refrigerant throughout, employ GPS bipolar ionization units salvaged from existing equipment for installation in new units, and include DDC controls with BMS interface capabilities for the VRF systems. The contract documents specify detailed construction sequencing with phased demolition and installation to allow continuous school operation, comprehensive mechanical details for all equipment connections and supports, and coordination requirements with architectural, structural, and electrical trades.
