Process payment for CO items once approved and should only occur during the regular progress estimate cycle. On occasion, agreements to pay for CO work is allowed using the PAY ADJUSTMENT POSITIVE bid item (i.e. change order is complete and is only pending final signatures; or a CO is approved mid-month and payment needs to be processed). The use of Pay Adjustment Positive can be used to temporarily process payment(s) to the contractor. It must be done with caution and include supporting documentation. Ensure that double payment is avoided by accurately processing the adjustments to the affected pay items once the CO is fully approved. Pay Adjustment Positive should never hold a value at the end of a project.
