The scope of work for the Haaren Hall Natatorium Mechanical Room and Water Heater Phase II Upgrades project at John Jay College, prepared by AI Engineers for the Dormitory Authority of the State of New York (DASNY Project No. 381260), encompasses architectural, structural, mechanical, electrical, and fire alarm upgrades to modernize and replace deteriorated infrastructure in the facility. Architecturally, the project involves replacing severely corroded metal doors in the pH Buffer and Sanitizer rooms with new stainless-steel doors (one rated for 3-hour fire protection) and installing new epoxy flooring in Mechanical Room CM10. Hazardous materials testing by GZA was conducted for asbestos, lead, PCBs, mold, and other regulated substances. Structurally, new access features including a fiberglass ladder with a safety cage, access platform, hoist beam, and hatch will be added to the pool equipment room sump pit. The bulk of the work centers on mechanical upgrades along with some plumbing work, including full demolition and replacement of corroded metallic components, degraded piping, sump pumps, and heat exchangers across multiple rooms (CM03, CM05–CM14). New systems will include upgraded sump pumps with BACnet interfaces, new steam-to-hot-water heat exchangers, pumps with VFDs, air separators, makeup air and exhaust fans, and ductwork for proper air circulation. The project also connects major components to the building’s BMS (Building Management System) for integrated control. Electrical work includes removal and replacement of wiring, conduits, disconnects, and control panels to support the new HVAC systems, makeup air units, and sump pumps. Two new emergency power branches Legally Required Standby and Optional Standby will be added to the generator system. Fire alarm work involves replacing detectors, relays, and control modules to integrate new HVAC fire/smoke dampers and duct detectors with the existing fire alarm network.
