Worked questions

1. Before bidding or performing covered public work, what should the contractor verify?

  • AThe owner may waive labor law
  • BA city business card replaces registration
  • Verify current DIR registration
  • DRegistration is needed only after final payment

Why C is correct

2. What is the core wage obligation on covered public work?

  • APay only the private-market bid rate
  • Meet prevailing-wage and payroll rules
  • CApply one statewide rate to every craft
  • DTreat every worker as an independent contractor

Why B is correct

Public works requirements depend on project, location, craft, classification, and dates. Contractors must use current official determinations and maintain supporting records.

3. A public-works foreman records total crew hours but not individual classifications, rates, or deductions. Why is that inadequate?

  • AThey permit false classifications if signed
  • BThey replace the construction schedule
  • They document payroll compliance

Why C is correct

The best answer is: They document payroll compliance. Certified payroll supports verification of prevailing wages and other labor duties. Certification increases rather than removes the need for complete and truthful underlying time and payroll records. The new fact pattern changes the setting, not the governing rule or management control. The other choices either skip a required step, apply a different rule, or fail to address the stated risk.
