John C Cox, I disagree with your advice. It is likely that a retired PE will not maintain a license and insurance due to costs, thus becoming an exPE. Second an engineers report should be an unbiased document that assesses design and performance of the work, such a document will go beyond the cost of the work at issue and really do you want an engineers report on a vernacular or even jackleg design. Pay for the day, get a release and move on.
