I have a project that has been under construction. The contractor installed regular DF#2 posts embedded in the concrete instead of Pressure-treated. However, he did coat all the bases of the posts with a moisture protection. The beams, trusses and roof sheathing are now on and the problem was recently discovered. The owner wants me to provide the jurisdiction with a letter approving the moisture protection instead of the required pressure treated members as indicated on the plans. I could also specify a concrete moisture coating to cover not only the pole footing but the bottom 6" or so of the wood post. What is your point of view and suggested plan of action?
