•
Location: Facility SH50
•
Objective: A turnkey modernization of the facility's mechanical, hydronic, and energy-management systems. This includes replacing legacy heat pumps and controls with new, high-efficiency equipment and integrating them into an upgraded Building Automation System (BAS).
Key Execution Constraints
•
Facility Occupancy: The facility will remain occupied throughout the project. •
Equipment changeovers to occur between April 1, 2026 through April 1, 2027.
•
Equipment On-Site: On-site demolition cannot begin until all major replacement equipment has been delivered and verified on-site.
•
Utility Outages: A written request for any utility shutdown must be submitted and approved at least 14 days in advance.
•
