Both uniform and point loads analyzed in the following calculations.Uniform loads are <br /> assumed to be standard due to load distribution from bearing walls,however,the additional <br /> PLL=.48klf*6'-0"=2.88 kips point load is conservatively considered here for any major beam supports from above. <br /> PTL(w/o stemwall DL)=1.12k1f"8'-0"=6.72k 2. Maximum loading on the grade beam was determined by inspection of the building <br /> PTL(w/stemwall DL)=1.92*8'-0"=11.52k geometry and through conservative assumptions regarding span lengths and support <br /> wall/foundation. All concrete walls assumed full tributary span of floor and roof members. <br /> Refer to attached calculations for <br /> analysis. <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 /> 8'-0". <br /> L120 ENGINEERING&DESIGN <br />
