Refer to attached calculations for analysis. <br /> Conclusion: <br /> Based on the loading and geometry of the structure we conclude that the foundation may be stabilized through the use of piles and <br /> connections per R&R.These are to be attached to the stem-wall(grade-beam)at an on-center(o.c.)spacing no greater than 6'-0"do <br /> connections <br /> L120 ENGINEERING&DESIGN <br />
