I'm well aware the TYPE of laws are common, and in my opinion, they are generally reasonable. The guy designing a bridge I might someday drive over better know what the Hell he's doing. But the wording of THIS law is shit. For comparison, At least in my state, as I understand it, you're allowed to call yourself a "contractor". But you are not allowed to call yourself a "licensed contractor", and you are not allowed to do things that require a licensed contractor unless you are indeed a licensed contractor. Likewise, in the contractor world, you are allowed to DIY almost anything, you are just sometimes required to get it inspected (and call before you dig). The wording of this law, it sounds like under no circumstance are you allowed to DIY engineering of any sort; even for stuff that you own, that is on your property. and that makes no damned sense.
