In March 2004, the Chicago City Council passed an ordinance requiring the City to report payments to subcontractors and suppliers on the City 's website. This ordinance applies to all City-funded, construction-related contracts awarded after June 28, 2004. In order to comply with this new ordinance, contractors meeting this criteria will be required to submit this form with each invoice for payment. The form reports the intended payments from prime contractors to subcontractors and suppliers from the invoice. The information from this form will be recorded in the City 's financial system and posted on the City website to be in compliance with the ordinance.
