SHEET NO. <br /> S180726-3 <br /> 111„, 2031 Rockefeller Ave SE, Everett,____ , WA 98201 <br /> LONGITUDE SUBJECT Foundation Stabalization/Jacking <br /> ONE TWENTY° <br /> ENGINEERING&DESIGN BY CMH DATE 08/07/2018 <br /> Maximum loading on grade beam determined <br /> based on building geometry,and through <br /> conservative assumptions regarding span <br /> lengths and support walls/foundation.Basically, <br /> all concrete walls assumed full tributary span of <br /> Case 1: floor members and roof members. <br /> 2-Story Point-Load=15k Design code:IBC 2015 <br /> (mid span) <br /> Refer to attached calculations V RoofFloor LL:snow):25 psf <br /> for grade beam analysis. Floor/Roof pL:r15psf <br /> Wall DL:10psf <br /> Roof Trib=0.5'40'max span=20' <br /> Case 2: Floor Trib=0.5'20'max span=10' <br /> 2-Story Uniform Load <br /> -DL=1,100 plf Note:Total load of 2500p1f <br /> LL=800 plf 1 conservatively used. <br /> -LL(snow)=600 Of <br /> Refer to attached calculations <br /> for grade beam analysis. <br /> 2'-2" (18" + 8") <br /> Pile and connection requirements per Pile and connection requirements per <br /> Ramjack West Remjack West <br /> 6'-0" Max - <br /> Conclusion: <br /> Based on the structure's loading and geometry, L120 concludes that the existing foundation may be stabilized through the use of <br /> piles and connections per Ram Jack West,provided the load to each pile is less than or equal to the values specified. The piles are <br /> to be attached to the stem-wall(grade-beam) at an on-center spacing no greater than 6'-0".The calculations included within this <br /> package assume a wood superstructure and concrete foundation with minimum reinforcement constructed per residential building <br /> codes and standard construction practices. <br /> L120 further recommends the installation of steel C-channels or equivalent at areas of significant cracking and/or settlement in the <br /> stem-wall. These additional elements are to span from pile to pile and be bolted to the existing foundation per Ram Jack West.The <br /> inclusion of these supplementary steel elements is at the discretion of Ram Jack West. <br /> L120 ENGINEERING&DESIGN <br />
