AMERICAN ENGINEERING TESTING,INC. AET Project No. 22-00012 <br /> frozen soils, snow, or ice, nor should the use of frozen fill soils be permitted. The contractor <br /> must protect base soils from freezing before and after fill placement, and before, during, and <br /> after concrete placement. If the interior footings will be exposed to freezing temperatures during <br /> construction, we recommend that you consider lowering the footings to protect against frost <br /> penetration into the footing subgrade soils. We recommend that a special pre-construction <br /> meeting be held to discuss the procedures and precautions that must be followed. <br /> 7.2 Excavation Sideslopes <br /> The excavations for this project must have sideslopes in accordance with OSHA Regulations <br /> (Standards 29 CFR), Part 1926, Subpart P, "Excavations" (can be found on www.osha.gov). <br /> Even with the required OSHA sloping, surface runoff flowing over the slopes can possibly cause <br /> sideslope erosion which could require slope maintenance. The responsibility to provide safe <br /> working conditions on this site lies solely with the contractors. <br /> 7.3 Observation and Testing <br /> The recommendations in this report are based on the subsurface conditions found at our test <br /> boring locations. Since the soil conditions can be expected to vary away from the soil boring <br /> locations, we recommend on-site observations by a Geotechnical Engineer, or the Engineer's <br /> representative,during construction to evaluate the effect of these potential changes. <br /> We recommend that all foundation bearing surfaces be observed by a Geotechnical Engineer or <br /> Engineering Technician immediately prior to concrete placement. Soil density testing should also <br /> be performed on all fill placed at the site to document that our recommendations, and the <br /> specifications, for compaction and moisture, have been satisfied. Where fill material type is <br /> important, laboratory sieve analyses should be performed to document that the actual fill meets <br /> the recommended gradation criteria. The building materials should also be tested in accordance <br /> with the project specifications and the building codes. <br /> Page 27 of 28 <br />
