Mississippi University for Women is requesting sealed bids for HVAC rooftop unit replacement at Whitfield Hall in Columbus, Mississippi, with bids due October 8, 2026. A pre-bid conference is scheduled for March 5, 2026, at 10:30 a.m. in the Facilities Maintenance Conference Room at 915 10th Street South, Columbus.

The scope covers removal of existing rooftop units RTU-1 and RTU-2 and installation of two new Trane Foundation 25-ton electric/electric packaged rooftop units (model EDK300A3S0A**07 or approved equivalent). Each unit must deliver 9,000 CFM airflow at 208–230V/60Hz/3-phase, operate on R-454B refrigerant with Symbio 700 controls, and include a 72 kW field-installed electric heater for two-stage heating. The contractor is responsible for all labor, equipment, materials, crane services, permits, testing, startup, commissioning, and incidentals for complete turnkey replacement. Mandatory preconstruction field verification is required to confirm existing equipment specifications, roof curb conditions, structural capacity, electrical system compatibility, ductwork dimensions, drainage routing, building automation system interfaces, and crane access feasibility before procurement and installation begins. Deliverables include demolition and refrigerant recovery, roof curb adaptation or reinforcement as needed, mechanical installation with ductwork modifications and condensate drainage, electrical work to accommodate the increased 72 kW load with code-compliant feeders and overcurrent protection, controls integration with the building automation system, factory startup coordination with an authorized Trane service technician, comprehensive testing and balancing, air handling verification, life-safety interlock restoration, operation and maintenance manuals, as-built documentation, owner training, and closeout documentation demonstrating code compliance and proper commissioning before final acceptance and owner turnover.
