We recently had this credit denied based on the fact that our contract did not explicitly state that the 10 month follow-up review is included in the activities of EAc3, even though we provided a confirmation letter that was signed by both parties and stated that we were contracted for both Fundamental and Enhanced Commissioning, including post-construction commissioning activities.
This appears to go above and beyond any requirement I know. If you follow the logic of the reviewer, the contract would have to explicitly name each commissioning task in order to count towards the credit. However, that was not requested, just the 10-month review.
We are now appealing this decision by providing the actual post-construction commissioning report with a timeline that shows that the review was carried out within the 10 months.
No real question here but just sharing our experience and inviting comments.
