(30 ILCS 500/30-30)
    Sec. 30-30. Design-bid-build construction.
    (a) The provisions of this subsection are operative through December 31, 2023.
    For building construction contracts in excess of $250,000, separate specifications may be prepared for all equipment, labor, and materials in connection with the following 5 subdivisions of the work to be performed:
        (1) plumbing;
        (2) heating, piping, refrigeration, and automatic
    
temperature control systems, including the testing and balancing of those systems;
        (3) ventilating and distribution systems for
    
conditioned air, including the testing and balancing of those systems;
        (4) electric wiring; and
        (5) general contract work.
    The specifications may be so drawn as to permit separate and independent bidding upon each of the 5 subdivisions of work. All contracts awarded for any part thereof may award the 5 subdivisions of work separately to responsible and reliable persons, firms, or corporations engaged in these classes of work. The contracts, at the discretion of the construction agency, may be assigned to the successful bidder on the general contract work or to the successful bidder on the subdivision of work designated by the construction agency before the bidding as the prime subdivision of work, provided that all payments will be made directly to the contractors for the 5 subdivisions of work upon compliance with the conditions of the contract.
    Beginning on the effective date of this amendatory Act of the 101st General Assembly and through December 31, 2023, for single prime projects: (i) the bid of the successful low bidder shall identify the name of the subcontractor, if any, and the bid proposal costs for each of the 5 subdivisions of work set forth in this Section; (ii) the contract entered into with the successful bidder shall provide that no identified subcontractor may be terminated without the written consent of the Capital Development Board; (iii) the contract shall comply with the disadvantaged business practices of the Business Enterprise for Minorities, Women, and Persons with Disabilities Act and the equal employment practices of Section 2-105 of the Illinois Human Rights Act; and (iv) the Capital Development Board shall submit an annual report to the General Assembly and Governor on the bidding, award, and performance of all single prime projects.
    For building construction projects with a total construction cost valued at $5,000,000 or less, the Capital Development Board shall not use the single prime procurement delivery method for more than 50% of the total number of projects bid for each fiscal year. Any project with a total construction cost valued greater than $5,000,000 may be bid using single prime at the discretion of the Executive Director of the Capital Development Board.
    (b) The provisions of this subsection are operative on and after January 1, 2024. For building construction contracts in excess of $250,000, separate specifications shall be prepared for all equipment, labor, and materials in connection with the following 5 subdivisions of the work to be performed:
        (1) plumbing;
        (2) heating, piping, refrigeration, and automatic
    
temperature control systems, including the testing and balancing of those systems;
        (3) ventilating and distribution systems for
    
conditioned air, including the testing and balancing of those systems;
        (4) electric wiring; and
        (5) general contract work.
    The specifications must be so drawn as to permit separate and independent bidding upon each of the 5 subdivisions of work. All contracts awarded for any part thereof shall award the 5 subdivisions of work separately to responsible and reliable persons, firms, or corporations engaged in these classes of work. The contracts, at the discretion of the construction agency, may be assigned to the successful bidder on the general contract work or to the successful bidder on the subdivision of work designated by the construction agency before the bidding as the prime subdivision of work, provided that all payments will be made directly to the contractors for the 5 subdivisions of work upon compliance with the conditions of the contract.
