Structural calc results vs. "usually done so" practice
[COLOR=#404040][FONT=Roboto]What do you do when you have a required footing size and the contractor wants to make it smaller. 12"dia vs 15"dia for a deck post footing. [/FONT][/COLOR]
[COLOR=#404040][FONT=Roboto]This is indirectly connected to the "insurance" forum here. I don't cary insurance, I don't have enough work to pay for it.[/FONT][/COLOR]
[COLOR=#404040][FONT=Roboto]Do I give in? Do I believe in the "I have 6 more decks to come...."? There is so much safety factor in the engineering calculations that it would probably be fine but I don't really want to assume responsibility for the builder, even if he has done many of these. Frustrating.[/FONT][/COLOR]
