SubSignal / Opportunities / Department of Transportation
When the Department of Transportation 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 $126M 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.

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.
