Occasionally, it is necessary to make changes to aContractor's Progress Estimate (Form C21C) and/or an Inspector'sMonthly Construction Progress Report (Form C-3B) after the fileshave been "permanently" updated, even though the updatehas been reviewed and approved previously. This requires thatchanges to the computer files be made by the Data ProcessingDivision.
In order to establish uniformity and protect the integrity ofthe computer files, the procedures outlined in the attached flowchart have been developed. These procedures are to be carefullyadhered to.
