How to get ready
- Watch for sources sought notices from these agencies. Answering one is often how a small business gets a recompete set aside.
- Look up the past awards on USAspending.gov to see what the work cost. Our USAspending guide shows how.
- Make sure you count as small under 541620 with the size standard checker, and see whether it's the right code for environmental consulting.
These are contracts USAspending.gov shows ending, whether or not the agency has announced a rebuy. Agency procurement forecasts list far fewer: only the planned buys civilian agencies publish ahead of time, under “planned buys” below when this code has a forecast page.

Frequently asked questions
What is a recompete?
When a federal contract's period of performance ends, the agency usually buys the same work again, often through a new solicitation. That new competition is a recompete. Agencies often post sources sought notices or draft solicitations months before the current contract ends.
How early should I prepare for a recompete?
Six to twelve months ahead is common. Learn what the agency buys, watch SAM.gov for sources sought notices and industry days, and introduce your business to the contracting office and its small business specialist before the solicitation is out.
Where does this data come from?
USAspending.gov's award data: definitive contracts and purchase orders under NAICS 541620 worth at least $250,000, with activity in the last 18 months and a current end date in the next 12 months. End dates can move when options are exercised or contracts are extended.
