Gave this some thought...
Speaking with framing experience, there's no way to snap out the floor with chalk line without a detailed drawing. Unless it's something simple or you snap out the same pattern over and over every day or something and just "know"??? But SOMEONE better know how to read plans to get everybody else started or you're in for trouble!!!
Plus, there's codes to where exactly the plumbing has to be, electrical boxes need to be, what room gets what, ect. And I'd be pissed if I gave a set of plans to a GC and came out with something different built. And the engineered set of plans would be "exhibit A" when I took them to court for at least half refund.
After SOMEONE snaps out the floor, everybody else can be average hammer operators. But there will be a floor snapped out before any hammer operator ever sets foot onto an open floor. Always! No way around it???
