• AET 7ob No. 20-06374 - Page 2 of 6 <br /> CONCLUSIONS AND REC4MMENDATONS <br /> Based on the results of our observations, hand auger borings, hand cone penetrometer probes and <br /> our review of the available information, it is our judgment the soils exposed in the mass excavation <br /> bottom for the building addition were suitable for support of the fill and structural loadings. <br /> The results of the soil compaction tests taken during filling operations indicate that all final tests <br /> met or exceeded the minimum specified compaction level at the elevations and locations tested. <br /> Test#10 did not meet the specified compaction level with the initial effort. We recommended the <br /> soils in the area of this test be recompacted and retested. The result of this retest(test#13R)met or <br /> exceeded the specified compaction level. <br /> These conclusions are intended as a summary. Read the remainder of the report for additional <br /> details. <br /> DESIGN INFORMATION <br /> We understand or assume that the construction underway will consist of an addition to the northeast <br /> corner of the existing building. We further understand this building will: <br /> � Have two above-grade levels. <br /> • Have a first floor elevation of 1024.0, matching the first floor elevation of the existing <br /> building. <br /> � Be supported by conventional spread footings designed using an allowable soil bearing <br /> pressure no greater than 2500 pounds per square foot (ps fl. <br /> • Have bottom-of-footing elevations at about 1020 for the perimeter footings and 1022 for the <br /> interior footings. <br />
