Ms. Dawn Bushnaq Bushnaq Studio Architecture + Design Plan Check Number: B2109-083, First Building Review February 2, 2022 be provided as needed. The Building Code Summary on Sheet G301 should be revised to state a separated occupancy design. See IBC Sections 503.1, 504.2, 508.3.2, and 508.4.3. 7. The south Level 3 refuge area shown in Life Safety Plan 1/G323 requires use of the "Business" rooms to achieve the minimum area for 112 occupants. Note that the business areas are labeled as a 'Donation Closet" and 'Multipurpose Room" per Level 3 Plan 1/A203. It is anticipated that these rooms will have contents that will limit their use as refuge spaces, and that the rooms may be locked or provided with future locks preventing access in an emergency. The design team should review the proposed refuge area and use of these rooms, and revise the design as needed. See IBC Section 420.6.1. 8. Sheet A610 includes operable windows located only 1.5 to 2.5 feet above the floor lines, and other windows with undefined heights. The building elevations show clear openings above the finished floor of 2 feet or less for Type "I", "I-1", and some "E" windows. Types "E", 'IF", "I", and "I-1" are used above the first story in resident rooms, daycare rooms, corridors, and common areas (e.g., lounges, etc.) where children are present. Type "I" windows are identified because they are located at upper stories and could be replaced with operable windows (e.g., Typeat a future date. The low openings are a dangerous falling hazard, especially in the resident and daycare rooms. Though the occupancies in this building are not addressed in Section 1015.8, we recommend increasing the window heights at the second and third stories. 9. Floor Assembly "FY on Sheet A902 references GA File No. RC 2601 as the listed assembly. This assembly is a roof -ceiling assembly and does not include insulation in the listing. Insulation is not permitted in rated assemblies unless specified; see "General Explanatory" Note 12 in GA- 600-2018 Section II. The assembly specified is generally not consistent with the referenced listing, including but not limited to the prefab floor joists and concrete topping. The listing also does not specify the required STC And ICC performance requirements. The listing should be revised. See IBC Sections 107.2.1, 703.2, and 1206. 10. The building is Type VA construction per the Building Code Summary on Sheet G301. One -hour rated roof assemblies are required per IBC Table 601. The roof assemblies on Sheet A902 should specify listed tested assemblies for the proposed construction. The listings should include the insulation type and thickness as part of the tested assembly. See IBC Sections 107.2.1, 703.2, and 1206, and 'General Explanatory" Note 12 in GA-600-2018 Section II. 11. The exterior and interior wood -framed walls are generally required to be at least one -hour rated walls per IBC Table 601 and Section 704.1. The wall assemblies on Sheet A901 generally appear intended to provide this minimum protection. See IBC Section 703.2. The following comments should be addressed: a. Listed tested assemblies should be specified for Wall Types "Al". ',A2"1 "AY. and "A10". b. Wall Types "W'. "A7", and'W" do not appear consistent with the referenced listing UL- U305. In addition, the assemblies do not have the same construction. Listings consistent with the proposed construction for each assembly should be specified. c. Wall Type "AT' does not appear consistent with the referenced listing UL-1.1311. The listing requires proprietary GWB and limits the insulation thickness to 3 inches. The required spacing for the resilient channels should also be specified. 3200 Cedar Street © 425.257.8810 O everetteps@everettwa.gov Everett, WA 98201 425.257.8857 fax everettwa.gov/permits Page 3 of 10
