NAICS 541715 contracts: questions vendors ask

What is NAICS code 541715?

NAICS 541715 is Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology). This U.S. industry comprises establishments primarily engaged in conducting research and experimental development (except nanotechnology and biotechnology research and experimental development) in the physical, engineering, and life sciences, such as agriculture, electronics, environmental, biology, botany, computers, chemistry, food, fisheries, forests, geology, health, mathematics, medicine, oceanography, pharmacy, physics, veterinary, and other allied subjects. 7,175 federal contracts under this code end within 12 months.

How many federal contracts under NAICS 541715 are expiring?

7,175 prime contracts in Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) (NAICS 541715) reach the end of their current period of performance within 12 months: 512 within 30 days and 1,789 within 90. They are held by 2,752 different vendors and were bought by 20 agencies. The figures are counted from USAspending, the government’s own record of prime contract awards, and rebuilt nightly.

When does the next NAICS 541715 contract end?

The soonest ends on Oct 20, 2026. The table on this page lists the 10 soonest to end, in order, with the incumbent, the awarding agency, the end date and the amount obligated so far. An end date is the date in the award record, not a forecast.

Which agencies buy research and development in the physical, engineering, and life sciences (except nanotechnology and biotechnology)?

The agencies with the most expiring work here are Department of Defense (4,583 contracts), National Aeronautics and Space Administration (1,017 contracts), Department of Health and Human Services (549 contracts). In total 20 agencies have work under Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) (NAICS 541715) ending within 12 months.

Does an expiring contract mean a recompete is coming?

Not on its own. A period of performance that ends is work somebody has to win again, but agencies also extend, consolidate, insource or cancel, and the award record does not say which in advance. Findingbase shows the dates and a renewal score built from five fixed rules, with the reasons each one fired; it does not predict the outcome and does not publish solicitations. The solicitation, when there is one, appears on SAM.gov.

How this page is built

Every contract here comes from USAspending, the federal government’s own record of prime contract awards. A contract appears when its current period of performance ends within 365 days. The table lists the 10 soonest to end — not the largest, and not the highest scoring — so it is a sample of what is really coming rather than a showcase. Award identifiers link back to the source. This page was last rebuilt for Oct 20, 2026.

10 of the 10 contracts in the table above carry a renewal score, and 7,175 of the 7,175 in the whole list do. A contract with no score has not been through scoring yet: that is not a low score, it is no score. Scoring works through the soonest expiry dates first.
