The contract shall include the names and addresses of all known subcontractors with subcontracts with an annual value that exceeds the small purchase maximum established by Section 20-20 of this Code, the general type of work to be performed by these subcontractors, and the expected amount of money each will receive under the contract. Upon the request of the chief procurement officer appointed pursuant to paragraph (2) of subsection (a) of Section 10-20, the contractor shall provide the chief procurement officer a copy of a subcontract so identified within 15 calendar days after the request is made. A subcontractor, or contractor on behalf of a subcontractor, may identify information that is deemed proprietary or confidential. If the chief procurement officer determines the information is not relevant to the primary contract, the chief procurement officer may excuse the inclusion of the information. If the chief procurement officer determines the information is proprietary or could harm the business interest of the subcontractor, the chief procurement officer may, in his or her discretion, redact the information. Redacted information shall not become part of the public record.
    (b) If at any time during the term of a contract, a contractor adds or changes any subcontractors, he or she shall promptly notify, in writing, the chief procurement officer, State purchasing officer, or their designee of the names and addresses of each new or replaced subcontractor and the general type of work to be performed. Upon the request of the chief procurement officer appointed pursuant to paragraph (2) of subsection (a) of Section 10-20, the contractor shall provide the chief procurement officer a copy of any new or amended subcontract so identified within 15 calendar days after the request is made.
    (c) In addition to any other requirements of this Code, a subcontract subject to this Section must include all of the subcontractor's certifications required by Article 50 of the Code.
