SOLICITATION NO. 1232SA26Q1082 - RFI RESPONSES - 08-12-2026.pdf

This is a Request for Information (RFI) and Questions and Answers document for Solicitation No. 1232SA26Q1082, with RFI responses dated August 12, 2026.

The project requires replacement of an air handling unit (AHU-1) with a factory-assembled, outdoor-rated unit designed for 7,500 CFM of 100% outside air, complete with variable-frequency drive (VFD) capable of stable operation and airflow control down to 2,700 CFM. The unit must include a chilled-water cooling coil and hot-water preheat coil sized for specified design conditions: cooling at 91.1°F dry bulb/75°F wet bulb entering air with 54°F leaving air, and heating at 16°F entering air with 60°F leaving air. Contractors must provide a DDC-capable factory controller suitable for integration with the building control system, including an integral weatherproof enclosure for control valves and piping accessories. Unit construction, casing, components, controls, and accessories must be rated for outdoor installation and continuous operation at specified conditions. The project also requires replacement of both sides of the chiller coils. Testing and balancing of systems is required, along with a full TAB report. New equipment must be integrated into existing controls, with no separate controls project planned. Contractors are not required to hire Siemens for controls work, and no new controls system is desired by the government.

The document addresses tax exemption status, with reference to Mississippi state requirements, and clarifies that compressor replacement on the chiller is not in scope. Period of Performance is currently 90 days from issuance of Notice to Proceed but will be extended based on equipment lead times, particularly for replacement rooftop AHUs (approximately 12 weeks) and replacement coils (shorter timeframe). Lead times are expected to be similar across all manufacturers of these product types.
