(a) For purposes of this section, the following definitions apply:

1. (1) “Project labor agreement” has the same meaning as set forth in paragraph (1) of subdivision (b) of Section 2500 of the Public Contract Code.
2. (2) “Skilled and trained workforce” has the same meaning as set forth in Chapter 2.9 (commencing with Section 2600) of Part 1 of Division 2 of the Public Contract Code.

(b)

1. (1) For a project undertaken by a public agency that is certified under this chapter, except as provided in paragraph (2), an entity shall not be prequalified or shortlisted or awarded a contract by the public agency to perform any portion of the project unless the entity provides an enforceable commitment to the public agency that the entity and its contractors and subcontractors at every tier will use a skilled and trained workforce to perform all work on the project or contract that falls within an apprenticeable occupation in the building and construction trades.

2. (2) Paragraph (1) does not apply if any of the following requirements are met:

   1. (A) The public agency has entered into a project labor agreement that will bind all contractors and subcontractors at every tier performing work on the project or contract to use a skilled and trained workforce, and the entity agrees to be bound by that project labor agreement.
   2. (B) The project or contract is being performed under the extension or renewal of a project labor agreement that was entered into by the public agency before January 1, 2021.
   3. (C) The entity has entered into a project labor agreement that will bind the entity and all of its contractors and subcontractors at every tier performing work on the project or contract to use a skilled and trained workforce.

(c) For a project undertaken by a private entity that is certified under this chapter, the applicant shall do both of the following:

1. (1) Certify to the lead agency that either of the following is true:

   1. (A) The entirety of the project is a public work for purposes of Chapter 1 (commencing with Section 1720) of Part 7 of Division 2 of the Labor Code.

   2. (B) If the project is not in its entirety a public work, all construction workers employed in the execution of the project will be paid at least the general prevailing rate of per diem wages for the type of work and geographic area, as determined by the Director of Industrial Relations under Sections 1773 and 1773.9 of the Labor Code, except that apprentices registered in programs approved by the Chief of the Division of Apprenticeship Standards may be paid at least the applicable apprentice prevailing rate. If the project is subject to this subparagraph, then, for those portions of the project that are not a public work, all of the following shall apply:

      1. (i) The applicant shall ensure that the prevailing wage requirement is included in all contracts for the performance of the work.
      2. (ii) All contractors and subcontractors at every tier shall pay to all construction workers employed in the execution of the work on the project or contract at least the general prevailing rate of per diem wages, except that apprentices registered in programs approved by the Chief of the Division of Apprenticeship Standards may be paid at least the applicable apprentice prevailing rate.

      3. (iii)

         1. (I) Except as provided in subclause (III), all contractors and subcontractors at every tier shall maintain and verify payroll records under Section 1776 of the Labor Code and make those records available for inspection and copying as provided by that section.
         2. (II) Except as provided in subclause (III), the obligation of all contractors and subcontractors at every tier to pay prevailing wages may be enforced by the Labor Commissioner through the issuance of a civil wage and penalty assessment under Section 1741 of the Labor Code, which may be reviewed under Section 1742 of the Labor Code, within 18 months after the completion of the project, by an underpaid worker through an administrative complaint or civil action, or by a joint labor-management committee through a civil action under Section 1771.2 of the Labor Code. If a civil wage and penalty assessment is issued, the contractor, subcontractor, and surety on a bond or bonds issued to secure the payment of wages covered by the assessment shall be liable for liquidated damages under Section 1742.1 of the Labor Code.
         3. (III) Subclauses (I) and (II) do not apply if all contractors and subcontractors at every tier performing work on the project or contract are subject to a project labor agreement that requires the payment of prevailing wages to all construction workers employed in the execution of the project or contract and provides for enforcement of that obligation through an arbitration procedure.
      4. (iv) Notwithstanding subdivision (c) of Section 1773.1 of the Labor Code, the requirement that employer payments not reduce the obligation to pay the hourly straight time or overtime wages found to be prevailing shall not apply if otherwise provided in a bona fide collective bargaining agreement covering the worker. The requirement to pay at least the general prevailing rate of per diem wages does not preclude use of an alternative workweek schedule adopted under Section 511 or 514 of the Labor Code.

2. (2) Certify to the lead agency that a skilled and trained workforce will be used to perform all construction work on the project or contract. All of the following requirements shall apply to the project:

   1. (A) The applicant shall require in all contracts for the performance of work that every contractor and subcontractor at every tier will individually use a skilled and trained workforce to complete the project.
   2. (B) Every contractor and subcontractor at every tier shall use a skilled and trained workforce to complete the project.

   3. (C)

      1. (i) Except as provided in clause (ii), the applicant shall provide to the lead agency, on a monthly basis while the project or contract is being performed, a report demonstrating compliance with Chapter 2.9 (commencing with Section 2600) of Part 1 of Division 2 of the Public Contract Code. A monthly report provided to the lead agency under this clause shall be a public record under the California Public Records Act (Division 10 (commencing with Section 7920.000) of Title 1 of the Government Code) and shall be open to public inspection. An applicant that fails to provide a monthly report demonstrating compliance with Chapter 2.9 (commencing with Section 2600) of Part 1 of Division 2 of the Public Contract Code shall be subject to a civil penalty of ten thousand dollars ($10,000) per month for each month for which the report has not been provided. Any contractor or subcontractor that fails to use a skilled and trained workforce shall be subject to a civil penalty of two hundred dollars ($200) per day for each worker employed in contravention of the skilled and trained workforce requirement. Penalties may be assessed by the Labor Commissioner within 18 months of completion of the project using the same procedures for issuance of civil wage and penalty assessments under Section 1741 of the Labor Code, and may be reviewed under the same procedures in Section 1742 of the Labor Code. Penalties shall be paid to the State Public Works Enforcement Fund.
      2. (ii) Clause (i) does not apply if all contractors and subcontractors at every tier performing work on the project are subject to a project labor agreement that requires compliance with the skilled and trained workforce requirement and provides for enforcement of that obligation through an arbitration procedure.
