ASSIGNMENT

1. What is the required separation (hours) between Group A and Group R occupancies? Assume the building is equipped with sprinklers.
2. Sketch a wall section of a metal stud wall with the required rating.
3. Repeat this for Groups I-3 and M with no sprinklers and a minimum STC of 50.
   

Don’t worry about the top and bottom connections of the wall, just think about the layers of material you need.

This thing used to have SO MANY walls. It's been scaled back a lot. Still ok, but not as fun as it was.
