A request for proposals shall include a statement of: the scope of the procurement contract, including the expected degree of minority business enterprise participation, as provided in § 14–303(b) of this article; a summary of the factors used to determine the expected degree of minority business enterprise participation for the procurement contract, including subcontracting opportunities identified for the project, any applicable North American Industry Classification System codes linked to the subcontracting opportunities, and the number of certified minority business enterprises in those industries; the factors, including price, that will be used in evaluating proposals; and the relative importance of each factor. A unit shall publish a request for proposals in the same manner as required for an invitation for bids. After receipt of proposals but before the procurement officer awards the procurement contract, a unit may conduct discussions with an offeror to: obtain the best price for the State; and ensure full understanding of: the requirements of the State, as set forth in the request for proposals; and the proposal submitted by the offeror. If discussions are conducted, the unit: shall conduct the discussions in accordance with regulations adopted under this Division II; shall provide an opportunity to participate to each responsible offeror who submits a proposal that, in the judgment of the procurement officer, is reasonably susceptible of being selected for award; shall treat all of those responsible offerors fairly and equally; may allow all of those responsible offerors to revise their initial proposals by submitting best and final offers, if discussions indicate that it would be in the best interests of the State to do so; may conduct more than 1 series of discussions and requests for best and final offers; and may not disclose to an offeror any information derived from a proposal of or discussions with a competing offeror.

If the procurement officer makes a written determination that oral presentations are unlikely to aid in the evaluation process, oral presentations are not required. Except as provided in paragraph (2) of this subsection: a proposal is irrevocable for the period specified in the request for proposals; and a best and final offer is irrevocable for the period specified in the request for best and final offers.

After obtaining any approval required by law, the procurement officer shall award the procurement contract to the responsible offeror who submits the proposal or best and final offer determined to be the most advantageous to the State considering the evaluation factors set forth in the request for proposals. A unit shall publish notice of a contract in excess of the small procurement amount specified in § 13–109 of this subtitle awarded under this section, or a lower amount set by the Board by regulation in accordance with Title 10, Subtitle 1 of the State Government Article in eMaryland Marketplace.

After receiving a request for a debriefing under paragraph (1) of this subsection, the procurement officer shall provide the debriefing: as soon as is feasible after receiving the request; and before the recommended contract award is presented for approval to the head of the unit or the Board. Except for information reasonably determined by the procurement officer to be confidential, proprietary, or privileged, a debriefing required under paragraph (1) of this subsection shall include all relevant information.
