    Sec. 20-10. Competitive sealed bidding; reverse auction.
    (a) Conditions for use. All contracts shall be awarded by competitive sealed bidding except as otherwise provided in Section 20-5.
    (b) Invitation for bids. An invitation for bids shall be issued and shall include a purchase description and the material contractual terms and conditions applicable to the procurement.
    (c) Public notice. Public notice of the invitation for bids shall be published in the Illinois Procurement Bulletin at least 14 calendar days before the date set in the invitation for the opening of bids.
    (d) Bid opening. Bids shall be opened publicly or through an electronic procurement system in the presence of one or more witnesses at the time and place designated in the invitation for bids. The name of each bidder, including earned and applied bid credit from the Illinois Works Jobs Program Act, the amount of each bid, and other relevant information as may be specified by rule shall be recorded. After the award of the contract, the winning bid and the record of each unsuccessful bid shall be open to public inspection.
    (e) Bid acceptance and bid evaluation. Bids shall be unconditionally accepted without alteration or correction, except as authorized in this Code. Bids shall be evaluated based on the requirements set forth in the invitation for bids, which may include criteria to determine acceptability such as inspection, testing, quality, workmanship, delivery, and suitability for a particular purpose. Those criteria that will affect the bid price and be considered in evaluation for award, such as discounts, transportation costs, and total or life cycle costs, shall be objectively measurable. The invitation for bids shall set forth the evaluation criteria to be used.
    (f) Correction or withdrawal of bids. Correction or withdrawal of inadvertently erroneous bids before or after award, or cancellation of awards of contracts based on bid mistakes, shall be permitted in accordance with rules. After bid opening, no changes in bid prices or other provisions of bids prejudicial to the interest of the State or fair competition shall be permitted. All decisions to permit the correction or withdrawal of bids based on bid mistakes shall be supported by written determination made by a State purchasing officer.
    (g) Award. The contract shall be awarded with reasonable promptness by written notice to the lowest responsible and responsive bidder whose bid meets the requirements and criteria set forth in the invitation for bids, except when a State purchasing officer determines it is not in the best interest of the State and by written explanation determines another bidder shall receive the award. The explanation shall appear in the appropriate volume of the Illinois Procurement Bulletin. The written explanation must include:
        (1) a description of the agency's needs;
        (2) a determination that the anticipated cost will be
    
fair and reasonable;
        (3) a listing of all responsible and responsive
    
bidders; and
        (4) the name of the bidder selected, the total
    
contract price, and the reasons for selecting that bidder.
    Each chief procurement officer may adopt guidelines to implement the requirements of this subsection (g).
    The written explanation shall be filed with the Legislative Audit Commission, and the Commission on Equity and Inclusion, and the Procurement Policy Board, and be made available for inspection by the public, within 14 calendar days after the agency's decision to award the contract.
    (g-5) Failed bid notice. In addition to the requirements of subsection (g), if a bidder has failed to be awarded a contract after 4 consecutive bids to provide the same services to the Department of Transportation, the Capital Development Board, or the Illinois State Toll Highway Authority, the applicable agency shall, in writing, detail why each of the 4 bids was not awarded to the bidder. The applicable agency shall submit by certified copy to the bidder the reason or reasons why each of the 4 bids was not awarded to the bidder. The agency shall submit that certified copy to the bidder within the same calendar quarter in which the fourth bid was rejected. This subsection does not apply if information pertaining to a failed bid was previously disclosed to a bidder by electronic means. If any agency chooses to provide information by electronic means, the agency shall have a written policy outlining how the agency will reasonably ensure the bidder receives the information. For the purposes of this subsection, "electronic means" means an email communication from the applicable agency to the bidder or a public posting on the applicable agency's procurement bulletin.
    (h) Multi-step sealed bidding. When it is considered impracticable to initially prepare a purchase description to support an award based on price, an invitation for bids may be issued requesting the submission of unpriced offers to be followed by an invitation for bids limited to those bidders whose offers have been qualified under the criteria set forth in the first solicitation.
    (i) Alternative procedures. Notwithstanding any other provision of this Act to the contrary, the Director of the Illinois Power Agency may create alternative bidding procedures to be used in procuring professional services under Section 1-56, subsections (a) and (c) of Section 1-75 and subsection (d) of Section 1-78 of the Illinois Power Agency Act and Section 16-111.5(c) of the Public Utilities Act and to procure renewable energy resources under Section 1-56 of the Illinois Power Agency Act. These alternative procedures shall be set forth together with the other criteria contained in the invitation for bids, and shall appear in the appropriate volume of the Illinois Procurement Bulletin.
    (j) Reverse auction. Notwithstanding any other provision of this Section and in accordance with rules adopted by the chief procurement officer, that chief procurement officer may procure supplies or services through a competitive electronic auction bidding process after the chief procurement officer determines that the use of such a process will be in the best interest of the State. The chief procurement officer shall publish that determination in his or her next volume of the Illinois Procurement Bulletin.
    An invitation for bids shall be issued and shall include (i) a procurement description, (ii) all contractual terms, whenever practical, and (iii) conditions applicable to the procurement, including a notice that bids will be received in an electronic auction manner.
    Public notice of the invitation for bids shall be given in the same manner as provided in subsection (c).
    Bids shall be accepted electronically at the time and in the manner designated in the invitation for bids. During the auction, a bidder's price shall be disclosed to other bidders. Bidders shall have the opportunity to reduce their bid prices during the auction. At the conclusion of the auction, the record of the bid prices received and the name of each bidder shall be open to public inspection.
    After the auction period has terminated, withdrawal of bids shall be permitted as provided in subsection (f).
    The contract shall be awarded within 60 calendar days after the auction by written notice to the lowest responsible bidder, or all bids shall be rejected except as otherwise provided in this Code. Extensions of the date for the award may be made by mutual written consent of the State purchasing officer and the lowest responsible bidder.
    This subsection does not apply to (i) procurements of professional and artistic services, (ii) telecommunications services, communication services, and information services, and (iii) contracts for construction projects, including design professional services.
