Please review my first attempt of the NCARB section vignette.
I am a little confused with the required space between ceiling and floor/roof slab. Does it have to be the largest duct on the floor + 8" for light fixture?
In my solution:
Above lab = 20" + 8" = 28"
Above level 1 ceiling = 24" + 8" = 32"
Above level 2 ceiling = 20" + 8" = 28"
Is this correct?
Also, does the slab on grade have to be above the grade line or below?
Thank you.
