I am new to the trade (about a 14 mo.) and a few weeks ago I started taking plans and specs home to study. I found a situation were the engineer did not size the duct work but provided a note to size duct to 11.5 S.F. coordinate with ceiling height. I asked my foreman what this was and oddly he did not know. He said the shop people would figure this out and not worry about it. He is a bit of a hillbilly (don’t get me wrong he is very good at installing duct however; I just have this need to know how things work).
BTW this is a R/A transfer. Can someone here please, school me as to what he is looking for? I get the coordination part; we have 16’’ from structure to ceiling.
