This distressed hangar was located on a relatively flat area within the airport complex. Figure 1 is a map showing the general site location and the topography of the area. 2.0 FILL PLACEMENT Compacted fill was placed during recent grading to prepare the subject building pads for the construction of the proposed hangar and associated structures and/or improvements. Fill material was derived from on site and import sources. Fill was generally placed in uniform compacted lifts at near optimum moisture content. Grading was performed using standard heavy-duty construction equipment. 3.0TESTING Testing was performed to supplement field observations in promoting compliance with the applicable project requirements. Testing of compacted fill addressed by this report was conducted within the previous two months. Field-testing of the compacted fill material was conducted in accordance with ASTM D2922 and D3017 (nuclear method). Results of the field-testing indicate that fill materials were compacted to the appropriate minimum percentage (90%) of the laboratory maximum dry density as determined by test method ASTM D-1557. Tabulated results of the field compaction testing performed are provided in the attached Table I, "Compaction Test Summary." Laboratory determination of the reference compaction values for the E:\10-6139\Rpt_Comp Testing, Bldg Pad.doc Report of Testing of Compacted Fill For Building Pad Area Proposed J etsource Hangar Page 2 Palomar Airport, Carlsbad, California September 7, 2004 CTE Job No. 10-6139 fill materials is provided in Table II, "Laboratory Test Results." The full-size plan sheet submitted herewith shows the approximate location of the compaction tests performed. 4.0 TREATMENT OF BUILDING PADS To prepare the building pads, areas receiving fill were over-excavated to the depth of competent natural material and a minimum three feet below existing and/or proposed grades. Based on the preparatory grading performed and our understanding of the project, we anticipate that all proposed spread-type building foundations will bear entirely in properly recompacted structural fill. 5.0 ADDITIONAL CONSTRUCTION OBSERVATION All additional grading and backfilling should be observed and tested to assure conformance with recommendations presented herein and in the approved project soils report (Preliminary Geotechnical Investigation, Proposed Airport Hangar, 2118 Palomar Airport Road, Carlsbad, California, CTE Job No. 10-6139G, dated April 30, 2003). 6.0 CONCLUSIONS AND RECOMMENDATIONS We conclude that the soil engineering and engineering geologic aspects of the grading are in compliance with the approved geotechnical report and addendum document(s) and the grading and/ or improvement plans ( City of Carls bad Drawing No. 4 20-2B). Proposed improvements shall be design and constructed in accordance with the recommendations of the referenced approved soils report.
