What this contract is for

Combined Sources Sought Notice and Notice of Intent to Award a Sole Source Contract for Hydrogen Maser Repair/Refurbished Notice ID: NB688000-26-02296 Contract Opportunity Type: Sources Sought/Notice of Intent Response Date: August 3, 2026 Product Service Code (PSC): 6640 NAICS Code: 334515 BACKGROUND The National Institute of Standards and Technology (NIST) is conducting market research to identify alternative sources that (a) are capable of meeting NIST’s minimum requirements for the following commercial products and commercial services and (b) would be interested in competing for that requirement: The NIST Time Realization and Distribution group operates an ensemble of atomic clocks (timescale) that realizes UTC(NIST), maintenance of which is one of NIST’s mission essential functions. Some of the constituent hydrogen maser atomic clocks are reaching end of life and exhibiting degradation of performance. To maintain continued accurate operation of the timescale these aging masers need to be addressed, either through refurbishment or replacement, Additionally, there are new revisions of various modules that will improve performance and extend the lifetime of these units – performing these upgrades will bring the performance of our aged units up to currently available maser atomic clocks. The services required as part of these refurbishments and upgrades are as follows: Item 1: Hydrogen maser refurbishment Quantity: 3 Specifications: 1.1: inspect hydrogen bulb, recoat if needed 1.2: check and adjust RF alignment 1.3: inspect thermal control board and components, repair if needed 1.4: test AC/DC power module, replace if malfunctioning or too old 1.5: inspect quartz oscillator, replace if not operating at spec 1.6: replace ion pumps 1.7: inspect physics package, replace a...

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
This listing has no set-aside restriction ("full and open competition"), meaning any business, large or small, can bid.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
