    Proposals must include a bid bond in the form and security as designated in the request for proposal. Proposals must also contain a separate sealed envelope with the cost information within the overall proposal submission. Proposals must include a list of all design professionals, public art designers, and other entities to which any work may be subcontracted during the performance of the contract.
    Proposals must meet all material requirements of the request for proposal, or they may be rejected as nonresponsive. The school district may reject any and all proposals.
    The drawings and specifications of the proposal may remain the property of the design-build entity.
    The school district must review the proposals for compliance with the performance criteria and evaluation factors.
    Proposals may be withdrawn prior to evaluation for any cause. After evaluation begins by the school district, clear and convincing evidence of error is required for withdrawal.
    After a response to a request for qualifications or a request for proposal has been submitted under this Section, a design-build entity may not replace, remove, or otherwise modify any firm identified as a member of the proposer's team unless authorized to do so by the school district.
