When the first quarter is submitted, it is advisable to make a copy (after it has been signed) that can be added to for the next quarter.
When the second quarter checklist is ready for submission, make a copy of it (after it has been signed) which will now include all material requirements and signatures for two quarters.
Continue this procedure of making copies of materials already used and signed for each quarter, and at the end of the project, you will have a Final MC Checklist completely filled out.
This method will eliminate finding missed pay items at the end of the project. A blank copy of the checklist is not needed for each quarter.
