Mr. Michael Snitko <br /> Washington Flippers, LLC <br /> Plan Check Number: CW1910-001, First Structural Review <br /> December 13, 2019 <br /> beam doesn't have a cantilever. The middle section through the dining area has had no <br /> changes to the structural truss system. Vaulted ceilings were only added in the kitchen and <br /> living room. Not the dining room. Thus the Beams are simply supported on the bearing walls <br /> and don't cantilever. Calculations are accurate, but drawings have been updated to show the <br /> ridgeline and the thicker line represents the beam. <br /> 16.The roof framing on Sheet S1 for the west end of the building appears to be primarily <br /> supported at the interior by wood posts. The size of the posts, and whether the posts are new <br /> or existing, is not specified. Based on a review of the existing and proposed framing plans, the <br /> posts will be subject to increased loading for the proposed design, in part due to high tributary <br /> loads caused by the cantilever condition in the 5 1/2"GLBs. Calculations substantiating the <br /> design of the posts should be submitted for review. The load path supporting the posts and <br /> transferring loads to the foundation shall also be substantiated. See IBC Sections 1604.1 and <br /> 1604.4. Calculations attached. Clarifying notes added to show posts are 6x6 D.F #2 posts <br /> 17.The framing layout on Sheet S1 appears to specify 2x framing spanning in the north-south <br /> direction for the entire width of the building east of the 5 1/2"GLBs. See IBC Sections 107.2.1 <br /> and 1603.1. The following comments should be address: <br /> a. The framing is specified as both 2x8 and 2x10 joists. It is presumed that the framing is <br /> discontinuous at the peak, though this is not shown in the plan. The size(s) and span(s) for <br /> the framing should be clarified. <br /> b. The framing appears intended to have intermediate support at interior beam and wall lines. <br /> The plan and Section B-B do not specify connections between the joists and supporting <br /> framing. Connections shall be specified. Dining room vaulted ceiling/ roof joists are 2x10, <br /> kitchen joists are 2x8. New joists are sistered to original truss joists in the modified sections. <br /> Trusses were not modified over the peak and across the dining room section. See original <br /> construction drawings for framing details. <br /> 18.The framing layout on Sheet S1 appears to indicate new wood posts in the exterior walls at the <br /> northwest and southwest building corners. See IBC Sections 1603.1, 1604.1, and 1604.4. The <br /> following comments shall be addressed: <br /> a. The sizes of the posts should be specified. <br /> b. Calculations substantiating the design of the posts should be submitted for review. Exterior <br /> corner wall supports can either be 6x6 posts or (3) 2x6 studs. No calculation should be <br /> necessary since (3) 2x6 studs are structurally adequate due to being braced in both north <br /> and south direction by the exterior wall. 6x6 post calculation is attached for reference and <br /> used on interior walls where post is not braced in all directions. <br /> 19.The framing layout on Sheet S1 appears to specify a new 4x12 beam over doorway in the north <br /> wall. The beam should be provided with vertical supports at each end. See IBC Sections <br /> 1603.1, 1604.1, and 1604.4. The following comments shall be addressed: <br /> a. The required framing and connections should be specified. <br /> b. Calculations substantiating the design of the posts should be submitted for review. <br /> Calculations are attached but generally not necessary when following prescriptive IBC code. <br /> O3200 Cedar Street © 425.257.8810 O everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> -age 5of8 <br />
