SubSignal / Opportunities / Department of the Interior
When the Department of the Interior awards a contract over $750,000 to a large business, federal acquisition rules require that contractor to file a small business subcontracting plan — a written commitment to subcontract part of the work to small businesses. These are 6 such awards, worth $115M in total.
A subcontracting plan is a legal obligation on the prime, not an open solicitation. Nobody will contact you. The window that matters is the first few weeks after award, while the prime is still assembling its team — here is how the rule works.
| Prime contractor | Work | Award | Plan type | Start |

| Excella, LLC | Other Computer Related Services | $20.6M | Individual Subcontract Plan | Sep 14, 2026 |
| General Dynamics Mission Systems, Inc. | Engineering Services | $11.8M | Individual Subcontract Plan | Jul 20, 2026 |
| Booz Allen Hamilton INC | Other Scientific and Technical Consulting Services | $4.9M | Individual Subcontract Plan | Aug 17, 2026 |
| Dowl, LLC | Engineering Services | $4.3M | Individual Subcontract Plan | Jul 24, 2026 |
| Dowl, LLC | Engineering Services | $3.8M | Individual Subcontract Plan | Jul 16, 2026 |
Federal contract awards are published on USASpending.gov, and each record carries a field stating whether the award requires a subcontracting plan. SubSignal reads that field, keeps only the awards where the answer is yes, and drops everything else — awards below the threshold, awards to small businesses that are exempt, and awards the contracting officer marked as having no subcontracting possibilities. What is left is a list of large companies with a live obligation to find small business partners. This page rebuilds every time the feed refreshes.
