One soil sample was collected and transported to the F&R laboratory for Standard Proctor testing. The results of Proctor P-1 are attached. Two soil samples were also collected and transported to the F&R laboratory for moisture verification testing. The equipment operator with Long Grading was informed that the final test results would be reported on July 6, 2004 after the laboratory testing is finalized. Note: The three in -place density tests did not meet 95% compaction, but were retested on July 6, 2004 with acceptable results.

The test results were discussed with Mr, Michael W. Sloan, P. One 12-foot long section, approximately 20-feet south of the existing building along the east w footings, required further excavation, At the time of this report, the area mentioned had be I I 'I excavated to a depth of approximately 10-feet with further excavation pending. Mr, Chris Doyn F&R Staff Engineer, agreed that the foundation in this area should be excavated, but provided formal recommendations. The representative with Matthews Construction stated that the grad would re -excavate the above mentioned area and re -compact the soil to the requir specifications, An isolated area in the south wall footing contained loose soils that should removed prior to concrete placement. Aside from the areas mentioned above, and based on the DCP test results, the near surfa foundation soils evaluated are suitable for support of the foundations designed based on allowable net bearing pressure of 2,500 pounds per square foot at the locations tested.. T findings and DCP test results are based on shallow surface hand augering; therefore, a de investigative study should not be inferred.

Upon arrival, it was noted that the foundation had been undercut 10-feet in depth and 10-feet length, and the entire width of the foundation, Soft soils were also encountered in a 9' x 9' x deep area adjacent to the foundation under the slab. F&R had recommended backfilling the' areas with flowable fill in the foundation and washed stone in the slab area, however, in order expedite the process, Matthews Construction decided to backfill both undercut areas wii flowable fill. The structural engineer increased the amount of rebar from three No, 3 bars to s No, 6 bars to be extended 4-feet into the foundation adjacent to the undercut area. 31 Once the area has been backfilled, the near surface bearing materials are suitable for t required bearing capacity of 2,500 pounds per square foot.
