Both uniform and point loads analyzed in the following calculations. Uniform loads are <br /> PTL(w/o stemwall oL)=.82k1f*6'-0"=4.92k assumed to be standard due to load distribution from bearing walls,however,the additional <br /> PTL(w/stemwall DL)=1.07*6'-0"=6.42k point load is conservatively considered here for any major beam supports from above. <br /> 2. Maximum loading on the grade beam was determined by inspection of the building <br /> Refer to attached calculations for geometry and through conservative assumptions regarding span lengths and support <br /> analysis. wall/foundation. All concrete walls assumed full tributary span of floor and roof members. <br /> Conclusion: <br /> Based on the loading and geometry of the structure we conclude that the foundation <br /> may be stabilized through the use of piles and connections per R&R. These are to be <br /> attached to the stem-wall(grade-beam)at an on-center(o.c.)spacing no greater than <br /> 6'-0". <br /> L120 ENGINEERING&DESIGN <br />
