You have done no such thing. Because it rains sometimes does not mean its raining right now, your example is ludicrous on its face, since they have to be signed off by codes inspectors or everything stops. Oh and you want to pretend or is it that you do not know any better that there is no reason what so ever to believe its coincidence. again value engineering is irellevant, they either pass code or not. You presented no such thing, worse passing on misinformation is not a presentation. I have no reason to respond to anyone who are not what they claim to be. you arent an engineer any more than the quack sanders is an architect.
