After twenty five years of rails I know exactly how the conversation goes.
Framer 1: Should we line all the posts up and turn them the same way?
Framer 2: No, the steel guys will figure it out.
Framer 1: Should we install backing in the walls for the grab rails?
Framer 2: No, the steel guys can find the studs.
Framer 1: Should we talk to the steel guys before we frame the stairs?
Framer 2: No, they will make it more difficult and it will take to much time. Just frame it and they will figure it out.
And this will go on for eternity.
