Here we go...2nd try. Here are my clearance calcs:
1st floor: 8'-4" clg., 8" space for lights, 24" for ducts
2nd floor: 9'-0" clg., 8" space for lights, 20" for ducts
lab: 15'-0" clg., 8" space for lights, 20" for ducts
A few comments/questions:
-I broke the slab on grade at the bearing walls.
-I broke the ceiling at the interior rated wall and partition wall. Is this right? Do I break the joists at the int. rated wall? I'm second guessing myself about everything now.
-Int. rated wall extends from top of 1st floor slab to underside of 2nd fl. slab, then from top of 2nd fl. slab to underside of roof slab. Correct?
Joists are embedded 2"-4" into the bearing walls.
Any help is greatly appreciated. Thank you!
