<br /> Dustin,
<br /> There are a number of issues that will need to be addressed in both the mechanical and building submittals:
<br /> 1. The detail for the pipe penetrations through the walls are okay with our inspectors. However, it is basically a
<br /> sketch and less than typically provided. Here is an example of a typical penetration detail. I recommend
<br /> updating it to be more clear. cie,t+e_d 1 (�

<br /> 2. My inspectors agree that the fire wrap may be used to satisfy the requirements to provide shafts for the
<br /> ducts. However,the wrap needs to extend through the upper GWB to the damper to provide continuity. Also,
<br /> the penetration through the GWB re MS a fire-stop. A detail should be provided that clearly shows the
<br /> construction required. C.t i c c , 6 _ e-f /4-3
<br /> 3. The assembly specified in Detail 3/A1.5 in the building drawings for the lid is "UL DES L524". I looked this up and
<br /> it does not match the detail in the drawings. The reference is not valid. Please send an updated listing that
<br /> matches the proposed construction. Otherwise,the detail will need to be revised. Note that the approval of the
<br /> building permit is on-hold pending resolution of this issue. LA i-,„tc• r e_c;,- 's-o re_,..))sc-c4 iVi.S
