In accordance with your request, Testing Engineers - San Diego, Inc. (TESD) has conducted grading observation and compaction testing during preparation of the above referenced project. Services described herein were provided by TESD from November 7, 2002 through November 20, 2002. As indicated in our field reports, a representative of this office observed placement of fill within the pad area. Building pad subgrade preparation included overexcavation to a minimum depth of 4 feet below pad grade and a lateral distance of 6 feet outside of the perimeter of the planned stmcture. The driveway area was overexcavated in accordance with our referenced geotechnical report. The bottom of the overexcavations were scarified, moisture conditioned and recompacted prior to the placement of fill. The approximate test locations are presented on the Plot Plan in Appendix A. Summaries of field and laboratory compaction test results are provided on Tables 1 and 2 in Appendix B. Results of our field observations and density testing indicate that the fill placed within the pad meets the relative connaction requirements of 90 percent or greater based on test method ASTM D-1557. It is our opinion tiiat the residential pad preparation including tiie placement of fill was conducted in substantial conformance with tiie referenced geotechnical report and local grading ordinances.
