more scrutiny on type 5A construction

This drawing demonstrates some of the graphic limits of architectural detailing. It is a plan view of a very common 1 hour rated wall that can be used for bearing or non-bearing conditions. It fails to explain several things:
-Intersections with other rated walls, floors, or ceilings.
-Penetrations through the wall

If a contractor doesn't have experience with rated construction then this wall assembly could turn out to have an effective fire rating of about 10 minutes.
