XL EagleOstensible subcontractor rule
Ostensible subcontractor rule. The ostensible subcontractor rule is an SBA size rule. If a subcontractor performs the primary and vital requirements of a contract, or the prime is unusually reliant on it, SBA can treat the prime and sub as affiliated. Their sizes are then combined, which can make the prime ineligible for a small business award.
SBA looks at the whole picture: who manages the work, who has the experience, who hires the workers, and who wrote the proposal. The rule generally does not apply when the subcontractor is itself a similarly situated small business.
Why it matters to a small contractor
If a large company offers to 'do everything' while you hold the small business contract, that is a red flag. Keep management, key staff, and the core work in your own hands, and make sure your proposal shows it. A size protest can cost you the award if the sub looks like the real contractor.
Example
A small firm bids a set-aside for HVAC maintenance and names a large company as sub for all technical work, with the large company's manager as project lead. A competitor files a size protest, and SBA finds the prime unusually reliant on the sub.
Ostensible subcontractor rule: common questions
What are primary and vital requirements?
They are the core tasks that define the contract, the work the agency is really buying. SBA decides this case by case.
How can I avoid ostensible subcontractor problems?
Perform the core work yourself, manage the contract with your own people, and show your own capability in the proposal.
