CITY OF EVERETT Public Works Department March 6, 2019 Holly Shoubridge Mortenson Construction 10230 NE Points Drive Kirkland, WA 98033 Holly.shoubridae@mortenson.com Owner: Providence Health and Services - Washington Job Address: 1700 — 13th Street Plan Check No: B1903-002 RE: Building Permit Review Letter, PRMCE — D Wing LVL 9 Dear Ms. Shoubridge, In response to the application for a building permit, the plans have been examined and you are advised that revisions may be necessary before a permit can be issued. Please review and respond to the comments below. Construction 1. UL listing U428 requires proprietary GWB. As generic Type X is not in the listing, the types of approved GWB (mostly Type C) should be shown on the plans for wall types S, T & W/A8.01. a. Note 6 on Sheet A8.01 indicates the requirement of referring to the UL listing for GWB type, however the three partition types above could cause confusion in the field for the building inspectors. 2. It is not clear how wall type HcA/A8.01 will provide two-hour fire -resistance as the 2nd layer of GWB needed for 2-hour fire -resistance stops above the ceiling. 3. The following comments apply to the horizontal shaft assemblies 17 & 21/A8.01 Listing AER-09038): a. The listing requires Type C GWB vs. the Type X GWB shown on the details. b. Please verify that the studs chosen do not exceed Span Table 1 provided in the listing. 4. Shaft detail 16/A8.01 appears to use both UL 469 for the vertical portions and AER-09038 for the horizontal portions of the assembly. Please verify as UL 469 allows Type X GWB for walls however AER-09038 requires Type C for horizontal applications.
