The NIST Large Tier 2-phase Design-build Services Master IDIQ contract provides design-build services for the National Institute of Standards and Technology's facilities and infrastructure needs at its Gaithersburg, Maryland campus. This multiple-award vehicle encompasses professional engineering services integrated with construction labor and materials to execute comprehensive facility projects, including scientific laboratory renovations, scientific apparatus and tool installations, infrastructure repairs and upgrades, and administrative space modifications. The contract was established through a two-phase selection process under Federal Acquisition Regulation subpart 36.3, wherein prospective contractors were prequalified based on qualifications submissions, with the highest-rated firms subsequently competing for individual task orders. Individual task orders under this vehicle are structured as firm fixed-price delivery orders with ceiling values up to $30 million, supported by a shared ceiling of $70 million across all awarded contractors and a period of performance extending through September 20, 2028.
The contract vehicle was awarded to small business concerns on September 21, 2023, following a total small business set-aside designation in the originating solicitation. Task orders issued under this Master IDIQ have ranged from $10,000 to approximately $3.9 million in ceiling value, with Belt Built Contracting, LLC, a minority-owned small disadvantaged business based in Crofton, Maryland, emerging as a primary award recipient. The task orders demonstrate diverse scope applications, including steam and condensate return service restoration ($3,885,862 ceiling, completion October 30, 2026), air handling unit replacement ($1,128,678 ceiling, completion December 31, 2025), electrical vehicle and auger infrastructure relocation ($100,992.57 ceiling, completion May 23, 2025), and miscellaneous design-build support services. All work has been performed at NIST's Gaithersburg, Maryland facility, with task order awards issued throughout 2023 and 2024, indicating active utilization of the vehicle's contract capacity.
