About this file

Written by GovTribe AI · Jul 23, 2026

This file contains architectural and engineering drawings for the West Town Elementary School HVAC and Plumbing Upgrades project located at 1113 University Street, Albany, Georgia. The project includes comprehensive replacement of heating, ventilation, air conditioning systems, and plumbing fixtures across three buildings (3000, 3010, and 3020) at the school campus. The scope encompasses demolition of existing mechanical equipment including wall-hung heat pumps, rooftop units, fan coil units, exhaust fans, and associated ductwork, followed by installation of new equipment including Carrier rooftop packaged units, Bard wall-hung heat pumps, Greenheck exhaust fans, ductless fan coil units, air handling units, ceiling heaters, and packaged terminal heat pumps. The project is organized into four construction phases designed to maintain occupancy of the school during renovation. Plumbing work includes replacement of water closets, urinals, lavatories, sinks, water coolers, and associated fixtures throughout the buildings. Electrical work involves disconnecting and reconnecting power circuits to all mechanical equipment, with existing panels retained for reuse. The drawings include mechanical demolition plans, new work plans, equipment schedules detailing capacities and specifications, piping and ductwork details, and general notes addressing contractor responsibilities including refrigerant recovery from existing R-22 systems.

The project involves extensive coordination requirements including field verification of existing conditions, temporary wall installation to separate work areas from occupied student spaces, coordination with utility companies for temporary power service to modular classroom units, protection of existing data, fire alarm, intercom, and security systems, and careful sequencing to avoid conflicts with structural members and other building systems. The contractor must provide modular classroom units to house displaced students during each construction phase, with no more than eight classrooms relocated per phase. Temporary domestic cold water piping connections are required for the modular units. Equipment removal includes recovery of R-22 refrigerant with cylinders returned to the owner for processing, and salvage of existing bipolar ionization units for reinstallation in new equipment. The project specifications reference standard SMACNA construction details for ductwork, ASHRAE 62.1 indoor air quality procedures for outdoor air requirements, and manufacturer installation instructions for all equipment. Cost details, bid dates, contract award dates, and project timeline information are not included in this drawing set.
