This bill mandates the payment of prevailing wages for construction projects related to data centers that have an electrical capacity of 250 kilowatts or greater, or are designed to have an average electrical usage of 500 kilowatt-hours or greater after construction. It establishes a series of eligibility and compliance requirements for contractors, including registration under "The Public Works Contractor Registration Act," submission of certified payroll records, and adherence to safety and performance standards. Contractors must also maintain specific insurance coverage and provide a performance and payment bond valued at no less than 150 percent of the contract value. Additionally, the bill holds contractors jointly liable for any unpaid wages owed to workers by subcontractors and prohibits third-tier subcontractors from performing work on these projects.

Furthermore, the bill outlines various operational requirements for contractors, such as maintaining daily sign-in sheets for workers, ensuring that all workers complete OSHA-compliant training, and conducting criminal history background checks and drug testing. It also restricts the use of temporary labor services to those enrolled in registered apprenticeship programs. For projects designed to have an average electrical usage of 2500 kilowatt-hours or greater, a project labor agreement with the local Building and Construction Trades Council is required to ensure alignment with state and local community interests regarding energy efficiency, quality, safety, and skilled labor.
