GeoDesign noted that the exposed foundation subgrade generally consisted of a brown-gray silty SAND (f-m) with gravel (f-c). GeoDesign noted that the exposed perimeter foundation subgrade for northwest, northeast,and southeast corners of the lot were covered in surficially loose and saturated material that could beprobed up to 6 inches; probing depths below the surficially loose and saturated material were less than 1 inch under the full weight of the user. For the remainder of the exposed foundation subgrade, penetration depths encountered were less than 1 inch under the full weight of the user;in-place density tests taken on the south,east, north, and west sides indicated that the material had been compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis. It is the opinion of GeoDesign that the exposed foundation subgrade is suitable for support of the intended structure and recommends that any surficially loose and saturated material be removed from the base of the foundation prior to the placement of concrete. A summary of our observations and density tests taken today can be found in the attached Nuclear a- - auge .-ta and Figure 1. Lot 118: ••on arrival,GeoDesign noted that foundation excavation subcontractor had finished digging the footing and crawl space area for Lot 118. GeoDesign noted that the exposed foundation subgrade generally consisted of a brown-gray silty SAND (f-m) with gravel (f-c)which could be penetrated less than 2 inches using a 1/2 inch diameter soil probe; in-place density tests taken on the west,south,and east side indicated that the material had been compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis. It is the opinion of GeoDesign that the exposed foundation subgrade is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and saturated material be removed from the base of the foundation,prior to the placement of concrete. A summary of,our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1.
