What happens after a successful bid protest, and can the agency still award to someone else?

Corrective action after a successful protest means the agency will fix the error, and they can still award to a different eligible small business. The agency agreed with your protest that the original awardee was ineligible, so they will re-evaluate the offers from eligible small businesses. The agency does not have to award the contract to your company. Under the Federal Acquisition Regulation (FAR), specifically FAR 33.103, an agency can take various corrective actions, which often involve re-evaluating proposals, amending the solicitation, or even canceling it and resoliciting. I've seen it go both ways, where the original protester gets the award, or the agency finds another qualified small business. For state and local work, the rules for corrective action are found in the specific state or local procurement code and the portal's vendor guide.
