(50 ILCS 20/20) (from Ch. 85, par. 1050)
    Sec. 20. Contracts let to lowest responsible bidder; competitive bidding; advertisement for bids; design-build contracts.
    (a) All contracts to be let for the construction, alteration, improvement, repair, enlargement, demolition or removal of any buildings or other facilities, or for materials or supplies to be furnished, where the amount thereof is in excess of $20,000, shall be awarded as a design-build contract in accordance with Sections 20.3 through 20.20 or shall be let to the lowest responsible bidder, or bidders, on open competitive bidding.
    (b) A contract awarded on the basis of competitive bidding shall be awarded after public advertisement published at least once in each week for three consecutive weeks prior to the opening of bids, in a daily newspaper of general circulation in the county where the commission is located, except in the case of an emergency situation, as determined by the chief executive officer. If a contract is awarded in an emergency situation, (i) the contract accepted must be based on the lowest responsible proposal after the commission has made a diligent effort to solicit multiple proposals by telephone, facsimile, or other efficient means and (ii) the chief executive officer must submit a report at the next regular meeting of the Board, to be ratified by the Board and entered into the official record, that states the chief executive officer's reason for declaring an emergency situation, the names of all parties solicited for proposals, and their proposals and that includes a copy of the contract awarded. Nothing contained in this Section shall be construed to prohibit the Board of Commissioners from placing additional advertisements in recognized trade journals. Advertisements for bids shall describe the character of the proposed contract in sufficient detail to enable the bidders thereon to know what their obligation will be, either in the advertisement itself, or by reference to detailed plans and specifications on file in the office of the Public Building Commission at the time of the publication of the first announcement. Such advertisement shall also state the date, time, and place assigned for the opening of bids. No bids shall be received at any time subsequent to the time indicated in said advertisement.
    (c) In addition to the requirements of Section 20.3, the Commission shall advertise a design-build solicitation at least once in a daily newspaper of general circulation in the county where the Commission is located. The date that Phase I submissions by design-build entities are due must be at least 14 calendar days after the date the newspaper advertisement for design-build proposals is first published. The advertisement shall identify the design-build project, the due date, the place and time for Phase I submissions, and the place where proposers can obtain a complete copy of the request for design-build proposals, including the criteria for evaluation and the scope and performance criteria. The Commission is not precluded from using other media or from placing advertisements in addition to the one required under this subsection.
    (d) The Board of Commissioners may reject any and all bids and proposals received and may readvertise for bids or issue a new request for design-build proposals.
    (e) All bids shall be open to public inspection in the office of the Public Building Commission after an award or final selection has been made. The successful bidder for such work shall enter into contracts furnished and prescribed by the Board of Commissioners and in addition to any other bonds required under this Act the successful bidder shall execute and give bond, payable to and to be approved by the Commission, with a corporate surety authorized to do business under the laws of the State of Illinois, in an amount to be determined by the Board of Commissioners, conditioned upon the payment of all labor furnished and materials supplied in the prosecution of the contracted work. If the bidder whose bid has been accepted shall neglect or refuse to accept the contract within five (5) days after written notice that the same has been awarded to him, or if he accepts but does not execute the contract and give the proper security, the Commission may accept the next lowest bidder, or readvertise and relet in manner above provided.
    (f) In case any work shall be abandoned by any contractor or design-build entity, the Commission may, if the best interests of the Commission be thereby served, adopt on behalf of the Commission all subcontracts made by such contractor or design-build entity for such work and all such sub-contractors shall be bound by such adoption if made; and the Commission shall, in the manner provided in this Act, readvertise and relet, or request proposals and award design-build contracts for, the work specified in the original contract exclusive of so much thereof as shall be accepted. Every contract when made and entered into, as provided in this Section or Section 20.20, shall be executed, held by the Commission, and filed in its records, and one copy of which shall be given to the contractor or design-build entity.
    (g) The provisions of this Section with respect to design-build shall have no effect beginning on June 1, 2018; provided that any design-build contracts entered into before such date or any procurement of a project under this Act commenced before such date, and the contracts resulting from those procurements, shall remain effective. The actions of any person or entity taken on or after June 1, 2013 and before the effective date of this amendatory Act of the 98th General Assembly in reliance on the provisions of this Section with respect to design-build continuing to be effective are hereby validated.
