Mr. Brad Rzechula <br /> Leading Edge Construction, LLC <br /> Plan Check Number: B1803-029, First Review <br /> May 4, 2018 <br /> 20.The design of the floor joists is specified as a deferred submittal per the notes on Sheet S-4.0 <br /> and S-5.0. See IBC Sections 1603.1.8 and 1606.2. The following comments shall be <br /> addressed: <br /> a. The floor joists support interior non-bearing walls. Design dead loads shall be specified in <br /> the General Notes on Sheet S-1.0 for the non-bearing walls. A note shall also be provided <br /> to see additional loading criteria provided in the drawings as identified in the following <br /> comments. <br /> b. The second story includes posts at Grids D/2.7 and D3.3 that support large concentrated <br /> loads from the Upper Level floor. The required concentrated dead and live loads at the <br /> supporting Main Level floor joist shall be specified. <br /> c. The second story includes wall lines on Grids 2.7/C-D and 3.3/C-D that support a large line <br /> load from the Upper Level floor. The required line dead and live loads at the supporting <br /> Main Level floor joists shall be specified. <br /> Lateral System: <br /> 21. Page 37 of the structural calculations appears to provide line loads for wind loading at"Level 2 <br /> of 3". See IBC Sections 1604.1, 1604.4, and 1609.1. The following additional information shall <br /> be submitted for review: <br /> a. Specify the chapter (i.e., ASCE 7-10 Chapter 27 or 28) and procedure used for the <br /> determination of wind loads on the main force resisting system. <br /> b. Provide detailed calculations substantiating the main force resisting system design wind <br /> loads. <br /> c. Provide loading diagrams for all levels of the structure including the roof. <br /> 22. Page 38 of the structural calculations appears to provide line loads for earthquake loading at <br /> "Level 2 of 3". See IBC Sections 1604.1, 1604.4, and 1613.1. The following additional <br /> information shall be submitted for review: <br /> a. Specify the procedure being used for the design (i.e., Equivalent Lateral Force or Modal). <br /> See ASCE 7-10 Sections 12.8 and 12.9. Note that the following comments presume the <br /> ELFP has been used. If the modal procedure has been used, provide documentation <br /> substantiating the lateral forces as required by Section 12.9. <br /> b. Provide calculations substantiating the seismic weight tributary to each level. <br /> c. Provide calculations substantiating the vertical distribution of the seismic base shear to <br /> each diaphragm level including the roof. <br /> 23.The Foundation and Main Level floor framing plans on Sheets S-3.0 and S-4.0, respectively, <br /> and Section 7/S4.1, indicate shear walls occur at the first story on Grid B. The shear walls are <br /> not specified on the plans. In addition, the plans appear to have a discrepancy on the <br /> presence of a wall at Grid B/3. The drawings should be reviewed and revised as needed. See <br /> IBC Sections 107.2.1 and 1603.1. <br /> 24.The design includes wood portal frames at the first story on Grid A.5 per Sheet S-4.0. <br /> Calculations substantiating the design of the portal frames shall be submitted for review. Note <br /> that the design does not qualify for use of the prescriptive design procedures of the IRC or IBC <br /> Section 2308 per Table 2308.2.1. The calculations shall substantiating the capacity of the <br /> e6of8 <br /> CITY OF EVERETT • 3200 Cedar Street • Everett,WA 98201 • (425) 257-8810 • Fax(425) 257-8857 <br />
