I don't know about where you all live, but aren't you tired of architects and engineers designing stuff on paper that isn't logical?
Whether it's a A/H hanging 8' above a drop ceiling with no access. A RTU 23' up on a 45 degree metal roof with no roof hatch. A 16" metal duct to fit through a triangle with a maximum side of 8". An RTU flue exhaust blowing directly into the side of the parapet wall 7" away, or replacing the 500+lbs pump in a 3'X5' area 4' off the ground. I could go on and on, but I digress. Anyway you get my drift.
I once talked with a guy from Germany who told me "All engineers/architects have to do two years in the field before they put anything on paper".
My poll question to you is: Do you think that it should be mandatory for architects and mechanical engineers in the USA to do the same?
