Please review my vignette. It looks pretty much identical to the NCARB solution but I have got a couple questions.
Are my ceiling clearances adequate and not oversized?
Above the lab, I have got 4" deck + 32" joist + 20" duck + 8" lighting = 64" total
On the right side of second floor, I have got 4" deck + 24" joist + 20" duct + 8" lighting = 56" total
On the right side of first floor, I have got 4" deck + 24" joist + 24" duct + 8" lighting = 60" total. I have considered the 24" duct as it needs to travel across the building from west (corridor) to east (lobby).
Is there a riser that connects the 32x20 duct in the corridor to the 24x20 duct in the lab? The duct drops?
Thanks!!
