Maximum loading on the grade beam was determined by inspection of the building <br /> analysis. 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 /> 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 /> 7'-0". <br /> L12O ENGINEERING&DESIGN <br />
