RFQ-0040-2026 air Handler VFD Installation

Bridgewater State University is requesting quotes for purchase, installation, and integration of four Variable Frequency Drives for air handler units at the Science and Mathematics Center in Bridgewater, Massachusetts under RFQ-0040-2026, with quotes due May 27, 2026 and a strongly encouraged site walkthrough on May 20 at 9:00 a.m.

The scope covers VFD equipment and enclosures, low and line voltage wiring, conduit work, BACnet communication integration with the existing Energy Management System, motor testing in Bypass, Hand, and Auto modes, Lock Out/Tag Out procedures, and removal and disposal of existing equipment. The four VFDs will control three-phase, 480-volt, 25 horsepower motors (SF-1 through SF-4); a fifth air handler (SF-5) will remain unaffected. Work must occur during normal business hours with only one air handler removed from operation at a time to maintain facility airflow and pressure differential.

Acceptable VFD manufacturers are Honeywell, Danfoss, or approved equivalents; all VFDs must incorporate a minimum 3% AC line reactor or equivalent DC link reactor technology. The vendor supplies all hardware, components, and permits and is responsible for equipment removal and disposal.

Pricing must be itemized with separate line items for labor and materials. A 50% payment bond is required, and prevailing wage rates apply to all labor. Work is performed at the Science and Mathematics Center, 24 Park Ave, Bridgewater. Site access for the walkthrough is available at the Operations Center, 200 Great Hill Drive; interested vendors must confirm attendance at least 24 hours prior by contacting 508-531-1296. Quotes should be submitted to Procurementservices@bridgew.edu.
