B430 HVAC Replacement

The B430 HVAC Replacement project focuses on replacing non-functional HVAC equipment and addressing airflow and balancing issues to enhance the functionality and efficiency of Building 430, a 41,000-square-foot facility with critical 24/7 operations. Key improvements include replacing all supply fans in the building’s four air handling units with new fan arrays and variable frequency drives (VFDs) for enhanced efficiency and redundancy. Other updates include installing new low-leakage dampers, electric steam humidifiers, and dedicated variable air volume (VAV) terminal units for improved occupant comfort and ventilation. The project will also address underfloor duct zone segregation, ensure proper sealing, and re-commission air and water systems for optimal performance.

Additional work includes extending the existing heating hot water system to new VAV terminal units, integrating updated control sequences into the HVAC system, and ensuring adequate indoor air quality and pressurization through modernized controls and monitoring devices. Construction will be executed while the building remains occupied, requiring phased implementation and temporary systems to avoid utility or power disruptions. The project also incorporates minor electrical renovations, adjustments to existing life safety systems, asbestos testing and abatement, ceiling replacement, and wall and carpet repairs, ensuring the facility maintains its critical operations seamlessly throughout the upgrade process.
