Building 215 Clean Room HEPA Filter Replacement

The National Institute of Standards and Technology (NIST) issued a Request for Information (RFI) to gather market input for the replacement and upgrade of HEPA filtration and related HVAC systems in Building 215’s Advanced Measurement Laboratory cleanroom. The effort aims to understand technical feasibility, cost, schedule, and risk associated with a phased, nine‑day outage strategy that maintains most of the cleanroom in operation. NIST seeks detailed feedback on outage constraints, cost breakdowns, contractor experience, and potential improvements to increase competition. • Replace approximately 1,200 terminal‑supply HEPA filters and associated connections. • Repair/replace about 70 VAV terminal units, 54 airflow monitoring devices, and 32 exhaust‑air control valves, plus ductwork modifications and re‑balancing. • Conduct testing, balancing, commissioning, and cleanroom certification for each outage phase while protecting sensitive research equipment. • Provide a rough‑order‑of‑magnitude cost estimate broken out by direct construction, HVAC/HEPA work, controls, testing, premium‑time staffing, and contingency. • Offer insight on the practicality of the 9‑day, 24‑hour‑per‑day outage window and suggest alternatives such as mock‑up bays or adjusted phasing.
