WMU FU-06 November 2006 Forward Landfill Project No.021605.07 1 per 4,900 cy. A summary of test results is shown in Table 3. Results of the tests are included in Appendix C.

The total number of passing tests recorded corresponds to a frequency of 1 per 376 cy, which satisfies the minimum required frequency of 1 per 500 cy. In, addition, oven moisture contents were performed at the minimum specified frequency of 1 per 5,000 cy. Areas that failed to meet the acceptable compaction were reworked and/or replaced and retested until a passing result was achieved. Summaries of the field moisture/density testing are tabulated in Appendix C. Upon completion of the subgrade fill on the slopes, the Contractor prepared the surface for geosynthetics placement by smooth drum rolling the area. Vector's CQA Monitor observed the smooth drum rolling procedure and advised the Contractor of areas where ridges, rough areas, and/or voids were present so that these areas could be reworked. Once the surface preparation was complete, the area was approved for geosynthetics placement. A subgrade acceptance form was prepared by Vector's Vector Engineering, Inc. • 143E Spring Hill Drive• Grass Valley,CA 95945•(530)272-2448 -12-
