' Project Description and Scope <br /> ' This project is a 30-unit apartment development in Everett. The structure will consist of a 7,800-sf <br /> basement garage with three levels of apartments above the garage. The total proposed area for the <br /> building will be approximately 28,500 sf. The garage construction will consist of concrete footings, <br /> walls, slab-on-grade, and a post-tensioned transfer slab. The upper levels will be light-wood framing <br /> with plywood shear walls and conventional hold-downs. <br /> Gravity Summary <br /> Design Per 2015 IBC <br /> ' Conventional Spread Footings & Slab-on-Grade <br /> PT Concrete <br /> Engineered Wood Joists <br /> ' Wood, PSL and Steel Beams & Columns <br /> Pre-Engineered Wood Roof Trusses <br /> ' Floor Gravity Design Loads <br /> Roof DL 15 PSF <br /> Roof LL (Snow) 25 PSF <br /> ' Floor DL (Residential) 26 PSF <br /> Floor LL (Residential) 40 PSF <br /> Common Areas/Exits LL 100 PSF <br /> PT Level DL 20 PSF + Self Weight <br /> Lateral Summary <br /> Design Per 2015 IBC &ASCE 7-10 <br /> ' Flexible Diaphragm Analysis <br /> Light-Framed Wood Shear Walls <br /> Special Reinforced Concrete Shear Walls <br /> ' Seismic Parameters <br /> ' Soil Site Class C (Per Geotechnical report by GeoEngineers, Inc. dated 02.03.06) <br /> R = 6.5 (Light-Framed Wood Shear Walls); 5 (Special Reinforced Concrete Shear Wall) <br /> I = 1.0 (Non-Essential Facility) <br /> Wind Parameters <br /> 110 MPH Wind Speed, 3-Sec Gust <br /> Exposure Category B <br /> IW- 1.0 (Non-Essential Facility) <br /> ' Decnphoâť‘ Project Summary By <br /> Checked <br /> ATN Date <br /> Date 01/07/21 <br /> O Checked <br /> ENGINEERING Scale Sheet No <br /> ' 250 4th Ave South holed Job No <br /> Suite 200 Rockefeller Square <br /> Edmonds,WA 98020 0460.10 1 <br /> 1 <br />
