f <br />Project Description <br />This project involves a new Connect Up program that will replace all electrical and water <br />meters with smart electronic meters by Snohomish County PUD. This phase of the project will <br />provide receiving, warehousing, and distribution of residential, commercial, and water meters <br />at (3) district sites. This signed structural calculation package includes project elements <br />designed for the 75th Street Business Center site. Structural design will be provided for new <br />steel framing to repair an existing hole in the existing mezzanine slab. An existing CMU shear <br />wall is being reduced in length by approximately 4 feet. Calculations will be provided to verify <br />the lateral capacity of the wall for in plane and out of plane lateral loads. A new steel lintel will <br />be designed for the widened opening. Anchorage will be designed for existing light gauge stud <br />walls to tie them to the existing ceiling. <br />Scope of Work <br />We will provide stamped structural calculations and construction drawings suitable for permit <br />and construction. <br />Basis of Design <br />Roof Dead 15 psf <br />Live 25 psf (snow) <br />Mezzanine Dead 40.7 psf <br />Live 125 psf (light storage) <br />CU Wall Dead 84 psf (fully grouted) <br />Seismic Parameters <br />V = Wp*[Sds/(R/le)] = Sds/(6.5/1) = Cs*Wp <br />Sds 0.913 <br />R 5.0 (special reinforced masonry shear wall) <br />Importance Factor, le 1 (Non -Essential Facility) <br />Wp = Seismic Dead Weight of Structure <br />Description By JDM Date 3 4 2022 <br />Project Summary Checked Date <br />ENGINEERING Scale NTS Sheet No. <br />250 4th Ave South project Job No. <br />EdmoSuit 20 98020 PUD 75th St Business Center 21352.10ds, 1 <br />
