(Soilogic) provided construction materials testing and observation services for the referenced project. Our services were provided on a part-time basis and included the observation and testing of utility backfill materials. Results of the observation and testing services completed during the referenced period are included with this report. During the referenced period, Soilogic personnel obtained one (1) representative sample of the excavated site soils for laboratory evaluation of the moisture density relationship of that material. The laboratory testing completed on the obtained sample included a standard Proctor (ASTM D-698) test. Results of the completed standard Proctor test were used to evaluate the percent compaction and moisture variability with reworked soils in the field and are included with this report. During the referenced period, Soilogic personnel performed field moisture/density tests on sewer and water utility backfill materials that had been placed and compacted prior to and during our site visits. The field moisture/density tests were completed at random locations and elevations within the backfill areas and were performed in general accordance with ASTM Specification D-2922. Results of the field moisture/density tests completed during the referenced period are included with this report. The field moisture/density test results met the project compaction requirement of at least 95% of the material’s standard Proctor maximum dry density and -1% to +3% of the material’s optimum moisture content.
