We are currently working on an NEC4 Option C Contract. We have submitted our usual application for payment with the costs incurred and the records that support this. We have had hours disallowed as the Project Manager assesses them as too high for the activity completed. We have called for a meeting to discuss as this is not correct in our opinion. The hours are justified and required by the Scope so the fact that they feel it took longer than they anticipated is not a disallowable cost in our opinion. Am I correct in this view?
