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 outlines specific 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 various types of insurance and provide a performance and payment bond valued at no less than 150 percent of the contract value.

Additionally, the bill establishes that contractors are jointly liable for any unpaid wages or benefits owed to workers by subcontractors and prohibits third-tier subcontractors from performing work on these projects. It restricts the use of temporary labor services to those enrolled in registered apprenticeship programs and requires contractors to maintain daily sign-in sheets for workers. Furthermore, all workers must complete specific construction training and undergo background checks and drug testing. For projects with 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.
