We have done some of fit ups utilizing flex drops as you say, but we know the impact they can have and how tight some calcs are. If we sway from the original we at least do proof calcs. If its small enough we don't have to provide calcs to the local AHJ for permitting and only need to supply a letter of intent, we mention the fact that the flex drops will be utilized and we have proof calcs if required.

I would do separate a "while we were at this location" letter to the owner. There is some level of moral (and legal) responsibility to report something that could be a dangerous condition. Is the "interference" because the AHJ might have missed something?
