    Sec. 35-40. Subcontractors.

(a) Any contract granted under this Article shall state whether the services
of a subcontractor will be used.  The contract shall include the names and
addresses of all subcontractors 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 for matters other than construction
 or the higher education chief
procurement officer, whichever is appropriate, and the
responsible State purchasing officer, or their
designee of the names and addresses and the
expected amount of money each new or replaced subcontractor will receive. Upon 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 this Code.

(d) For purposes of this Section, the changes made by Public Act 98-1076 apply to procurements solicited on or after January 1, 2015 (the effective date of Public Act 98-1076).
