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 /> 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 /> 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 /> 6'-0", spanning pile-to-pile. <br /> 120 ENGINEERING&DESIGN <br />
