I am working on a project that underwent a split review. We have received and accepted our final design review submission. A short while after this, the owner decided that they would like to potentially add additional design credits that were never submitted before. Now that this has come up, I have a few questions:

1.) Has anyone else been in a similar situation?
2.) Is this possible? If so, how is it handled? Is it viewed like an appeal and a fee is applied/required or since it is a previously unsubmitted credit, can it go in with the construction credits no issue?
3.) If submitted, does it reopen all previously submitted design credits for another review?

This is a NC 2009 project.

Thanks
