Reply to "Fire Resistance Rating of a proposed design"

Hi, 

Sorry for the delay in the postmortem.  I'm pleased to say that the design we proposed was accepted for a 2-hour rating.  I'm attaching the explanation of the design logic that we submitted with the architectural drawings.

In a nutshell, we argued that the only meaningful commonality among all 2-hour rated walls is a double layer of 5/8" type X drywall.  All other variants in wall configuration don't seem to be highly relevant.

Thanks again.
