f <br /> Test#1 — Exca�ation Base (Near Mid-paint) <br /> DCP Depth Per Blow Avq. / N-Vafue Estimated Load <br /> 824 MM (32.4°} 43.3 MM/N—7.3 2563 PSF <br /> Based upon our observations and tests, it is recommended that all arganics and undocumented fill <br /> be excavated from the building pad, and replaced with a granular engineered fill to proposed footing <br /> elevation (estimated @ 4 to 5 feet} and below the building slab. This�II material should be <br /> cansolidated with a vibratory compaction device at intervals of approximately 8 to 10 inches. <br /> In our opinion, with the noted corrections, the observed and tested sub-grade soils are acceptable, <br /> and would be expected to meet an assumed minimum bearing capacity requirement of 2000 PSF, <br /> for the proposed construction. Our observafions and subsequent soil evaluation on this date is <br /> limited in scope to soil conditions observed within the completed excavation, and to the depths <br /> achieved by shallow probes and a dynamic cone penetrometer test. <br /> Sincerely, <br /> Itco AIlied Engineering Company Reviewed By: <br /> � .
