Note

For REVISION projects, the marking process is the same as for ADDITION_OR_ALTERATION projects, with one key difference:

  • In REVISION projects, the Development Stage of unmodified Proposed Work or Floor in Section should be marked as PERMITTED.
  • In ADDITION_OR_ALTERATION projects, it should be marked as EXISTING.
