The previously <br /> placed engineered fill had also been removed to approximately the new floor elevation. We performed <br /> two shallow hand auger borings west of the existing basement wall to an approximate depth of 3Y2 feet , <br /> below planned lower floor elevation. The hand auger borings were placed approximately 10'west and 8' <br /> and 16' north of the existing west wall of the basement. <br /> The soil profile encountered in the hand auger borings appeared to consist of 1' to 2' of granular fill, <br /> underlain by natural sandy lean clay in a firm condition. An 8' deep test pit had been previously <br /> excavated near the west wall of the demolished garage. The test pit walls indicated the natural soils <br /> gradually sloped downward toward the west. <br /> Based on our observations and the excavator, it is our opinion that the existing fill thickens towards the <br /> west of the planned addition to approximately 4' to 5'below the new planned bottom of footing elevation. <br /> We recommend excavation of the existing fill in order to expose the natural soils. The excavation should <br /> be sized to provide 1:1 lateral oversize for the depth of engineered fill required. The granular non organic <br /> soils that were previously excavated can be used as engineered fill. Any new engineered fill should be <br /> compacted in thin lifts to a minimum of 95% of Standard Proctor density. <br /> As variations in soil conditions may exist at locations and elevations other than those of our borings, we <br /> recommend that we be contacted to observe the soil conditions during site preparation. We recommend <br /> in-place field compaction tests be performed in the compacted fill, if required. Deep soil borings were not <br /> performed at the site, our firm cannot warrant the soil conditions below the depth of our shallow hand <br /> auger boring. <br /> REVIEWED BY: � :. ; :A� .,:_ .. . <br /> Kevin Zalec, P.E. <br /> Staff Engineer <br /> This report shall not be reproduced,except in full,without pnor permission of Element Matenals Technology.
