Description
The RFI response due date has been extended to October 26, 2026. Site Visit The National Institute of Standards and Technology (NIST) will conduct an optional site visit in connection with its Request for Information (RFI) for the Building 215 Cleanroom HEPA Filter Replacement requirement at the NIST Gaithersburg campus. The purpose of the visit is to help interested vendors understand the existing conditions and provide informed responses to the RFI.
The visit is for market research only. Attendance is not required to respond to the RFI or to participate in any future solicitation. This site visit does not constitute a solicitation or a request for proposals or quotations.
NIST will not award a contract or reimburse attendance or response costs on the basis of the RFI. RFI responses will be used for planning purposes and will be treated as information, not offers. The Government will host a site visit on Friday, October 9, 2026, at 9AM EST at the following location: National Institute of Standards and Technology 100 Bureau Drive, Building 215 Lobby Gaithersburg, MD 20899 Offerors interested in attending the site visit must submit their request for visitor badge via email to [email protected] and [email protected] by no later than Wednesday, October 7, 2026.
Offerors shall use the email subject line: Site Visit – B215 HEPA Filter RFI All requests must include the following information: Visitor’s full legal name. Visitor’s country of citizenship. NIST Gaithersburg is a secure federal facility.
On the date of the site visit, all Visitors to NIST Gaithersburg may access the site, through the Visitor Center from the main gate (Gate A) at W. Diamond Ave. and Bureau Drive. All visitors must be preregistered and present photo identification and vehicle registration information upon arrival.

REQUEST FOR INFORMATION (RFI) BUILDING 215 ADVANCED MEASUREMENT LABORATORY (AML) CLEANROOM REPAIR AND HEPA FILTER REPLACEMENT Solicitation/Reference No.: 1333ND26RNB190014 1. PURPOSE OF THIS REQUEST FOR INFORMATION The National Institute of Standards and Technology (NIST) is conducting market research pursuant to Federal Acquisition Regulation (FAR) Part 10 and FAR 15.201 to obtain industry feedback concerning the scope, schedule, phasing, cleanroom outage requirements, technical and performance risks, and estimated construction cost associated with the Building 215 Advanced Measurement Laboratory (AML) Cleanroom Repair and HEPA Filter Replacement project.
NIST previously solicited this requirement under Solicitation No. 1333ND26RNB190014. NIST did not receive an acceptable offer under that solicitation. NIST is therefore reassessing the requirement and acquisition approach before determining whether and how to resolicit the project.
NIST is particularly interested in identifying aspects of the requirement that may materially affect industry participation, constructability, schedule feasibility, pricing, risk, or the ability of contractors to submit competitive proposals. Industry is encouraged to provide candid feedback and to identify recommended changes that could improve constructability, competition, schedule feasibility, cost certainty, and overall project execution while continuing to meet NIST’s mission and cleanroom operational requirements.
2. RFI / MARKET RESEARCH NOTICE THIS RFI IS ISSUED SOLELY FOR INFORMATION AND ACQUISITION PLANNING PURPOSES. IT DOES NOT CONSTITUTE A REQUEST FOR PROPOSAL (RFP), INVITATION FOR BID (IFB), REQUEST FOR QUOTATION (RFQ), OR OTHER SOLICITATION.
The Government does not intend to award a contract based on responses to this RFI. Responses will be treated as information only and shall not be construed as offers or proposals that can be accepted by the Government to form a binding contract. The Government will not reimburse respondents for costs incurred in preparing or submitting information in response to this RFI or for participating in any follow-up discussions.
This RFI does not obligate the Government to issue a solicitation or award a contract, nor does it restrict the Government’s ultimate acquisition approach. Respondents are advised that information submitted in response to this RFI may be used by NIST in developing or revising the acquisition strategy, statement of work, specifications, schedule, phasing requirements, outage requirements, Government cost estimate, and future solicitation.
Respondents should clearly identify and mark any proprietary, confidential, or commercially sensitive information contained in their responses. Respondents should avoid including proprietary information unless necessary to provide a meaningful response. 3.
PROJECT BACKGROUND The project involves repair and modernization work within the Building 215 Advanced Measurement Laboratory cleanroom located at the NIST Gaithersburg Campus. The AML cleanroom encompasses approximately 1,800 square meters and includes approximately 750 square meters of Class 100 cleanroom space. The facility supports sensitive NIST research activities and contains specialized and, in some instances, irreplaceable scientific equipment.
The project generally includes, but is not limited to: Replacement of approximately 1,200 terminal supply HEPA filters; Repair and/or modification of HEPA filter connections; Testing, balancing, certification, and recertification of affected HEPA filters and cleanroom spaces; Replacement of approximately 70 variable air volume (VAV) terminal units; Replacement of approximately 54 airflow monitoring devices; Installation of approximately 32 exhaust air control valves; Modification and repair of associated ductwork; Rebalancing of associated air-handling and exhaust systems; Verification
