Now you know why bids are so low. These clowns doing that type of work are easily able to under bid those who plan it right. The bad part of it is the AHJ,s let them get away with it because their " THE BIG BOYS". I have seen this too many times in more than one area/state. Junky work make all of us look bad. Those of us who try and plan to do work correctly are getting under bid by these short cutters.
