The contracting officer may treat a group of orders as a single unit for administration of progress payments if each order is subject to the same liquidation rate.
The contracting officer shall ensure that any excess of unliquidated progress payments over the amount permitted by the liquidated rate specified in the contract is promptly corrected through one (1) or more of the following:
