(a) A protest based on alleged improprieties or ambiguities in a solicitation must be filed at least 10 days before the due date of the bid or proposal, unless a later protest due date is specifically allowed in the solicitation. If a solicitation is made with a shortened public notice period and the protest is based on alleged improprieties or ambiguities in the solicitation, the protest must be filed before the due date of the bid or proposal. Notwithstanding the other provisions in this subsection, the protest of an invitation to bid or a request for proposals in which a pre-bid or pre-proposal conference is held within 12 days of the due date must be filed before the due date of the bid or proposal if the protest is based on alleged improprieties or ambiguities in the solicitation. A protest based upon alleged improprieties in an award of a contract or a proposed award of a contract must be filed within 10 days after a notice of intent to award the contract is issued by the procurement officer.
(b) If the protester shows good cause, the procurement officer of the contracting agency may consider a filed protest that is not timely.
