Existing home construction was removed to allow for the <br /> new home construction activities . Poor soils existed at the site , <br /> requiring excavation and refilling soil corrective work. Our firm <br /> was directed by Mr. Jim Render of Render Development, Inc . , to be <br /> present at this site on a full-time basis during all poor soil <br /> removal and initial sand placement work . <br /> OBSERVATIONS <br /> During the period of October 2 through October 28 , 1998 , we were <br /> present at the site during all excavation activities . We observed <br /> poor soil removal work and the placement of sand fill materials <br /> immediately following excavation. <br /> A preliminary soil investigation was performed by Allied Test <br /> Drilling Company and reported on June 30 , 1998 . In conjunction <br /> with this work, three soil test borings , identified as B-1 through <br /> B-3 were placed on the site . The site soil correction work and soil <br /> test borings were focused on the first two lots west of Tonkawa <br /> Road (County Road #135 ) and immediately north of a driveway/road <br /> identified as Birch Lane . <br /> The borings identified old fill material overlying organic silt and <br /> brown and black fibrous peat materials beneath the fill soils . <br /> Beneath these soft organic soils, there was some soft gray clay <br /> material and then gray waterbearing sand materials. The sand <br /> materials were deemed as suitable for a foundation soil system. <br /> However, the fill soils , organic soils , and the soft clay soils <br /> were generally not suitable for foundation soil purposes, with the <br /> exception of leaving some remnant clay materials in place above the <br /> sand. <br />
