AET Project No. 20-06374 — Page 3 of 8 <br /> SOIL OBSERVATIONS AND TESTING <br /> Excavation Observation and Results <br /> Personnel from AET performed observations and testing of the soils in the mass excavation <br /> bottoms for the entire building addition footprint. The results of these services were provided in ' <br /> our Report of Excavation Observations and Compaction Testing, dated September 27, 2006. <br /> Briefly, that report states that the soils observed in the bottoms of these excavations should � <br /> provide adequate suppori of the fil] and structural loads. Reference should be made to that report <br /> for more details about the soil conditions; our observation techniques, and the results of our , <br /> observations. <br /> Compaction TestinQ Results <br /> AET personnel have performed compaction tests in fill placed during building addition <br /> construction. The results of these field density tests were compared to the laboratory Standard <br /> Proctor maximum dry densities (ASTM: D698) far different soil types to calculate the <br /> compaction levels for each test. The results of our compaction tests were presented previously in <br /> our Report of Excavation Observations and Compaction Testing, dated September 27, 2006. In <br /> summary, the soils at the locations and elevations tested were compacted to levels that should <br /> adequately support the structural building loads <br /> REINFORCING STEEL OBSERVATIONS <br /> Prior to placement of concrete, AET personnel observed the reinforcing steel present in the <br /> footings for the building addition. Our observations were performed on a will-cal] basis, when <br /> requested by the contractor. During our observations, we judged the following items for <br /> confonnance to the most current structural drawings available at the project site: <br />
