Some of the Preliminary Information Sheets I receive for jobs say, "Certified Payroll Reports Required". Some of the Preliminary Information sheets I receive say, " This is a Prevailing Wage Project. Certified Payroll Reports Must be provided". Is there a difference? Some jobs I know I need to provide the Owner Operator Listing Statement of Compliance along with the invoices I send out. Do I need to provide the Owner Operator Listing Statement of Compliance only if the Preliminary Info asks for Certified Payroll Reports? If I am told the job is a Prevailing Wage job and I do not have the Prelim Info yet should I assume that it requires the Owner Operator Listing Statement of Compliance also?
