The old loose fill is not considered adequate to provide support for the proposed <br /> building. In order to provide adequate support for the building at,this site, the building pad <br /> Should be cleared of all vegetation and any surface debris. ,.Once the building pad has been <br /> cleared, the old fill should be excavated and stockpiled for reuse as engineered fill. The <br /> depth of the old fill at the test hole locations is presented next: <br /> Test Hole Depth of Old Fill,_�ft� <br /> H-1 3.2 - <br /> H-2 1.2 ' <br /> The depth of the old fill can and will vary between test holes. Once the old fill has <br /> been removed, the subgrade thus exposed should be scarified for a depth of 6 inches and <br /> recompacted as recommended in App'.endix A. Fill placed on the building pad should be <br /> placed as engineered fill as recommended in Appendix A The over excavation of the old <br /> fill and the placement of engineered`'fill should extend a minimum of.5 feet beyond the t` <br /> building pad. The old fill and on site soils are suitable for use as engineered fill, however, <br /> if these materials are utilized for engineered fill the following exception should apply: the <br /> fill should be placed and compacted'at a moisture content that is at least 2% over the <br /> optimum moisture content as determined in the ASTM D1557 Compaction test. Fill that <br /> i <br /> meets minimum compaction requir.ements but does not meet minimum moisture <br /> i <br /> 'k <br /> requirements shall be considered unacceptable. <br /> A potential concern is the high ground water elevation in the area. Depending on <br /> i <br /> the time of year that the project is constructed, the elevated ground water level may make <br /> t <br /> f <br /> ERs G <br /> d � E <br /> 4Tsor\ <br /> 7 <br /> 6 <br /> ii <br />
