    (a) Any contractor and each subcontractor who participates in public works shall:
        (1) make and keep, for a period of not less than 3
    
years from the date of the last payment made before January 1, 2014 (the effective date of Public Act 98-328) and for a period of 5 years from the date of the last payment made on or after January 1, 2014 (the effective date of Public Act 98-328) on a contract or subcontract for public works, records of all laborers, mechanics, and other workers employed by them on the project; the records shall include (i) the worker's name, (ii) the worker's address, (iii) the worker's telephone number when available, (iv) the worker's social security number, (v) the worker's classification or classifications, (vi) the worker's gross and net wages paid in each pay period, (vii) the worker's number of hours worked each day, (viii) the worker's starting and ending times of work each day, (ix) the worker's hourly wage rate, (x) the worker's hourly overtime wage rate, (xi) the worker's hourly fringe benefit rates, (xii) the name and address of each fringe benefit fund, (xiii) the plan sponsor of each fringe benefit, if applicable, and (xiv) the plan administrator of each fringe benefit, if applicable; and
        (2) no later than the 15th day of each calendar month
    
file a certified payroll for the immediately preceding month with the public body in charge of the project. A certified payroll must be filed for only those calendar months during which construction on a public works project has occurred. The certified payroll shall consist of a complete copy of the records identified in paragraph (1) of this subsection (a), but may exclude the starting and ending times of work each day. The certified payroll shall be accompanied by a statement signed by the contractor or subcontractor or an officer, employee, or agent of the contractor or subcontractor which avers that: (i) he or she has examined the certified payroll records required to be submitted by the Act and such records are true and accurate; (ii) the hourly rate paid to each worker is not less than the general prevailing rate of hourly wages required by this Act; and (iii) the contractor or subcontractor is aware that filing a certified payroll that he or she knows to be false is a Class A misdemeanor. A general contractor is not prohibited from relying on the certification of a lower tier subcontractor, provided the general contractor does not knowingly rely upon a subcontractor's false certification. Any contractor or subcontractor subject to this Act and any officer, employee, or agent of such contractor or subcontractor whose duty as such officer, employee, or agent it is to file such certified payroll who willfully fails to file such a certified payroll on or before the date such certified payroll is required by this paragraph to be filed and any person who willfully files a false certified payroll that is false as to any material fact is in violation of this Act and guilty of a Class A misdemeanor. The public body in charge of the project shall keep the records submitted in accordance with this paragraph (2) of subsection (a) before January 1, 2014 (the effective date of Public Act 98-328) for a period of not less than 3 years, and the records submitted in accordance with this paragraph (2) of subsection (a) on or after January 1, 2014 (the effective date of Public Act 98-328) for a period of 5 years, from the date of the last payment for work on a contract or subcontract for public works. The records submitted in accordance with this paragraph (2) of subsection (a) shall be considered public records, except an employee's address, telephone number, and social security number, and made available in accordance with the Freedom of Information Act. The public body shall accept any reasonable submissions by the contractor that meet the requirements of this Section.
    A contractor, subcontractor, or public body may retain records required under this Section in paper or electronic format.
    (b) Upon 7 business days' notice, the contractor and each subcontractor shall make available for inspection and copying at a location within this State during reasonable hours, the records identified in paragraph (1) of subsection (a) of this Section to the public body in charge of the project, its officers and agents, the Director of Labor and his deputies and agents, and to federal, State, or local law enforcement agencies and prosecutors.
    (c) A contractor or subcontractor who remits contributions to fringe benefit funds that are jointly maintained and jointly governed by one or more employers and one or more labor organizations in accordance with the federal Labor Management Relations Act shall make and keep certified payroll records that include the information required under items (i) through (viii) of paragraph (1) of subsection (a) only. However, the information required under items (ix) through (xiv) of paragraph (1) of subsection (a) shall be required for any contractor or subcontractor who remits contributions to a fringe benefit fund that is not jointly maintained and jointly governed by one or more employers and one or more labor organizations in accordance with the federal Labor Management Relations Act.
