The on-site soils are suitabie tor structural fill. Howevor, the sands can be <br /> difficult to compact due to their grain-size distribution. <br /> LIMLTA7IQN.� <br /> The analyses, conclusions, and recommendations contained in this report are based on site <br /> conditfons as they =xisted at the time of our exploration and assume that the soils encoun- <br /> tered in the test pits are representative of subsurface conditions on the site. If the <br /> subsurtace conditions encountered during construction are significantly ditterent from th�se <br /> observed in our explorations, we should be advisad at once so that we can review the�e <br /> conditions and reconsider our recommendations where necessary. <br /> This report has been prepared for the exclusive use of Thomas Kelly and his <br /> representatives for specific application to this project and site. Our recommendations and <br /> conclusions are based on observed site materials, and selective laboratory testing and <br /> engineering analyses. Our conclusions and recommendations are professional opinions <br /> derived in accordance with curreni standards of practice within the scope of our services <br /> and within budget and time constraints. No warranty is express=d or implied.
