Both uniform and point loads analyzed in the following calculations.Uniform loads are <br /> PSL=0.351f*8'-0"=2.8 kips assumed to be standard due to load distribution from bearing walls,however,the additional <br /> point load is conservatively considered here for any major beam supports from above. <br /> PLL=0.64k1f*8'-0"=5.1 kips 2. Maximum loading on the grade beam was determined by inspection of the building <br /> PTL(w/o stemwall DL)=1.53k1f*8'-0"= geometry and through conservative assumptions regarding span lengths and support <br /> 12.3 k wall/foundation. All concrete walls assumed full tributary span of floor and roof members. <br /> PTL(w/stemwall DL)=1.8k1f*8'-0"= <br /> 14.4 k <br /> Refer to attached calculations for Conclusion: <br /> analysis. 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 /> 8'-0". <br /> L120 ENGINEERING&DESIGN <br />
