What is the maximum allowable crack size dimension in a post-tension concrete slab before it is considered a "structural" crack, in Arizona, USA? Is there a certain standard for this. I have tried looking for it in my state's ROC rules but they have nothing for what is considered to be a "structural" crack in a post-tension concrete slab. It's hard to give warranties without having specific measurements and standards to abide by.
Edit: This is for a on-ground slab with an ABC foundation
