PROJECT NO. SHEET NO. <br /> S200309-2 <br /> PROJECT 7425 Lower Ridge Rd, Everett WA 98203 <br /> LONGITUDE SUBJECT Foundation Stabilization/Jacking <br /> ONE TWENTY° <br /> ENGINEERING&DESIGN BY ZT DATE 5/22/2020 <br /> Case 1: Point Load Maximum loading on grade beam determined <br /> based on building geometry,and through <br /> conservative assumptions regarding span <br /> 8'-0"Span:(Conc w/L6x6x3/8) lengths and support walls/foundation.Basically, <br /> all concrete walls assumed full tributary span of <br /> Case does not apply. Examination floor members and roof members. <br /> of site photographs show that the Design code:IBC 2015 <br /> wall and foundation elements to be ` ' <br /> supported have uniform loading �/ Roof LL(snow ground):25 psf <br /> Floor LL:40 psf <br /> with no openings,doorways,or <br /> unique roof geometry that would / Floor/Roof DL:15 psf <br /> cause point loads. L/2 L/2 Wall DL:10 psf <br /> Pile Reaction=700p1f*8'=5.6 k Roof Trib=0.5*30'=15' <br /> *8.0 k conservatively used for Typical Fir Ht=10' <br /> minimum pile capacities. <br /> Case 2: Uniform Load <br /> 8'-0"Span:(Conc w/L6x6x3/8) <br /> -DL=100+15*15=325 plf 2'-2" (18" + 8") <br /> -SL(snow)=25*15=375 plf <br /> *Total load of 700 plf <br /> conservatively used <br /> Refer to attached calculations for <br /> analysis. <br /> Pile and connection requirements per Pile and connection requirements per <br /> contractor contractor <br /> 8'-0" MAX <br /> WITH CONTINUOUS L6x6x3/8 ANGLE <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 thickened slab edge at an on-center(o.c.)spacing no greater than 8'-0"with <br /> continuous spanning L6x6x3/8"angle. <br /> L120 ENGINEERING Si DESIGN <br />
