GeoDesign noted that the exposed footing subgrade consisted of a brown-gray silty SAND (f-m)with gravel (f-c)that had been exposed using a grade blade. The exposed foundation subgrade was evaluated using a 1/2 inch diameter soil probe and a Troxler Moisture-Density gauge. Penetration depths encountered ranged from 1 to 3 inches and in-place density tests indicated that the exposed foundation subgrade material had been compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1. It is the opinion of GeoDesign that the exposed foundation subgrade observed today was currently suitable for support of the intended foundation load. GeoDesign recommends that any loose and saturated material be removed from the base of the foundation prior to the placement of concrete. Lot 115: GeoDesign noted that the foundation subcontractor had excavated the footing and crawl space areas for Lot 115 using a Komatsu PC120 excavator with a grade blade.
