Second shot at finding any differences:
1st FloorTop of Footing: -3'-0"
Ceiling: 8'-4"
Lights: 8"
Ducts: 24" (derived from a 32" x 24" max. duct size)
Joists: 28"
2nd Floor:Ceiling: 8'-4"
Lights: 8"
Ducts: 24" (derived from a 32" x 24" max. duct size)
Joists: 20"
Parapet: 2'-8"
Meeting Room:Ceiling: 26'-0"
Lights: 8"
Ducts: 12" (derived from a 32" x 12" max. duct size)
Joists: 28"
Parapet: 2'-8"
Question: Are the ceiling heights measured from the Top of Slab or the Grade Line at the first floor? I do see that in the NCARB example the Meeting Room ceiling is about centered on the 2nd Floor joists...
