NIST Boulder Galvanized Steel Stair Installation – Building 2 Mechanical Room

The National Institute of Standards and Technology (NIST) in Boulder, Colorado, is seeking a qualified small business contractor to perform a construction project involving the removal and replacement of two existing wooden stair assemblies in the lower-level mechanical room of Building 2. The work includes the demolition and legal disposal of a five-riser and a nine-riser wooden staircase, followed by the field-fabrication and installation of new galvanized steel stair systems with slip-resistant industrial treads and code-compliant handrails and guardrails. Due to constrained access within the mechanical room, all fabrication and welding must occur on-site, and the new stairs must be securely anchored to the existing structure. The contractor is responsible for coordinating with adjacent mechanical, electrical, and plumbing systems, protecting nearby surfaces, conducting thorough cleanup, and ensuring full compliance with applicable building codes, OSHA regulations, and NIST-specific safety and security protocols. All personnel requiring site access must undergo a background investigation and obtain a Personal Identity Verification (PIV) badge within 30 days of the Notice to Proceed, adhere to strict identification and access rules, and comply with additional security protocols including pre-approved after-hours work and delivery restrictions. Proposals are due by 5:00 PM Mountain Time on May 15, 2026, and must be submitted as sealed physical copies to the Boulder facility. The solicitation is a total small business set-aside under FAR 19.5, with a North American Industry Classification System (NAICS) code of 236220. Offerors must submit a three-volume proposal including a technical approach limited to 20 single-sided pages, a detailed schedule, and a lump-sum price using the SF 1442. A site visit is scheduled for April 29, 2026, and questions are due by May 8, 2026. The award will follow a Lowest Price Technically Acceptable (LPTA) method, with technical acceptability evaluated based on demonstrated experience, ability to mobilize within 10 days of award, and a realistic schedule. The performance period is estimated at 120 calendar days following a projected Notice to Proceed date of June 1, 2026. All construction must meet applicable federal standards including FAR 52.246-12, FAR 52.236-5, and 1352.246-70, and the contractor must submit material sub
