All hood equipment is <br /> located at grade next to the walk-in cooler, away from the building, meaning the ducts will not be traveling up <br /> along the exterior of the building to the roof. <br /> As for the Type-1 duct specifically, once the duct penetrates the exterior of the building, it will be extending a <br /> minimum of 18"from the face of the building, giving us our required minimum clearance from combustible <br /> surfaces. Please refer to drawing QF804 showing this condition. As for maintaining the fire wrap, I can ask the <br /> mechanical engineer to provide a detail for how the duct wrap will be transitioning to the 18" fire pad. This pad <br /> will be flashed and protected, which we can again provided a detail for if required. <br /> Again, because the Type-1 duct is now routing away from the building and no longer running along the <br /> exterior of the building to the roof, I was not aware that the additional support and bracing related to the <br /> hoods would need to be shown in the architectural drawings, as those items are already noted in the separate <br /> hood permit set as "duct hangars and supports per SMACNA HVAC duct construction standards". Reference <br /> sheet QF800. <br /> We will revise detail 8/A9.1 to include the fastener specifications. <br /> Thanks, <br /> Johnathon Cave <br /> Interior Designer <br /> CLARK I BARNES. <br /> 1401 West Garfield Street, Seattle,WA 98119 <br /> O (206) 782.8208 ext. 814 I D (206) 259.2612 <br /> www.clarkbarnes.com <br /> From: Drew Martin<dmartin@everettwa.gov> <br /> Sent: Friday, December 4, 2020 10:43 AM <br /> To:Johnathon Cave<jcave@clarkbarnes.com> <br /> Cc:Tim Platt<timp@bethanynw.org> <br /> Subject: RE: Permit# B2008-003-Architectural Drawing Set <br /> Jonathan, <br /> I see two issues that need to be addressed: <br /> 1. The plan for the Type 1 duct does not clearly indicate how the wrap is maintained through the wall. In addition, <br /> it is anticipated that the duct is running up the exterior of the wall. This is fine, but the duct needs to have <br /> protection until the 18" clearance is provided. The wrap is not designed to be exposed, so it will need to be <br /> 2 <br />
