SHEET NO. <br /> iii,___lI' S200303-3 <br /> 111 sisimI, PROJECT 738 Crown Dr, Everett, WA 98203 <br /> LONGITUDE SUBJECT Foundation Stabilization/Jacking <br /> ONE TWENTY° <br /> ENGINEERING&DESIGN BY DATE 4/19/2020 <br /> Maximum loading on grade beam determined <br /> Case 1: Point Load based on building geometry,and through <br /> conservative assumptions regarding span <br /> 7'-0"Span: (Conc Only) lengths and support walls/foundation.Basically, <br /> all concrete walls assumed full tributary span of <br /> Pt Load= 1800 plf*7ft=12.6 kip floor members and roof members. <br /> Conservative load of 1800plf Design code: IBC 2015 <br /> utilized in this calculation package. V Roof LL(snow ground):25 psf <br /> Floor LL:40 psf <br /> / Floor/Roof DL: 15 psf <br /> L/2 L/2 Wall DL: 10 psf <br /> Case 2: Uniform Load Roof Trib=0.5*40'max span=20' <br /> Floor Trib=0.5*20'max span= 10' <br /> 7'-0"Span: (Conc Only) Deck Trib=0.5*10'=5' <br /> -DL= 100+15*(20+10+5)=625 plf - _ - Typical Fir Ht=10' <br /> -LL=40*(10+5)=600 plf <br /> -SL(snow)=25*20=500 plf <br /> Conservative load of 1800plf T <br /> utilized in this calculation package. <br /> Refer to attached calculations for 2'-2" 8" 8,, <br /> analysis. <br /> y <br /> Pile and connection requirements per Pile and connection requirements per / <br /> contractor contractor <br /> 7'-0" MAX <br /> Conclusion: <br /> Based on the loading and geometry of the structure we conclude that the foundation may be stabilized through the use of piles and <br /> connections per R&R. These are to be attached to the stem-wall (grade-beam)at an on-center(o.c.)spacing no greater than 7'-0". <br /> L120 ENGINEERING&DESIGN <br />
