This is a Bid Invitation document issued by Mississippi University for Women (MUW) in Columbus, Mississippi, for the replacement of HVAC rooftop units at Whitfield Hall. The project involves the removal of two 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 operation using R-454B refrigerant with Symbio 700 controls and include a 72 kW field-installed electric heater for two-stage heating. A mandatory 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. Sealed bids are due October 8, 2026, at 2:00 p.m. at the Facilities Maintenance Office. The contractor is responsible for all labor, equipment, materials, crane services, permits, testing, startup, commissioning, and incidentals for complete turnkey replacement.

The project requires mandatory preconstruction field verification 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. Deliverables include demolition, refrigerant recovery, roof curb adaptation or reinforcement, mechanical and electrical installation with ductwork modifications, condensate drainage management, building automation system integration, factory startup coordination with an authorized Trane service technician, comprehensive testing and balancing, life-safety interlock restoration, operation and maintenance manuals, as-built documentation, owner training, and closeout documentation demonstrating code compliance and proper commissioning.
