Questions people ask about DOI contracts
How do I find DOI contract opportunities?
Department of the Interior posts its solicitations on SAM.gov, and its smaller supply orders can also appear on DIBBS. This page lists the ones that are open right now, soonest deadline first, and leaves out award notices, sole source intents and notices that only existing contract holders can answer.
What does DOI buy?
Land and water management, park and refuge maintenance and construction, scientific services, equipment and IT.
Can a small business win a DOI contract?
Yes. Of the 40 open notices shown here, 21 are reserved for small business or for a certification such as 8(a), HUBZone, WOSB or SDVOSB. You need an active SAM.gov registration and a Unique Entity ID before you can be awarded anything.
What should I know before bidding on DOI work?
The bureaus buy for themselves, so watch the National Park Service, Bureau of Land Management, Fish and Wildlife Service, Bureau of Reclamation and USGS. Much of the work is seasonal and remote.
