SUMMARY of OBSERVATIONS: LOT 220: Today, GeoDesign noted that DDS had completed the excavation of the footing,crawl space, and crawl space drain for Lot 220 prior to our arrival on-site. Previously, GeoDesign noted that the Lot 220 area had been over-excavated-3-4 feet down to firm and unyielding ground(during removal of surcharge material)and brought back to plan grade with material compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis. GeoDesign noted that the exposed foundation subgrade material consisted of a brown SAND(f-m)with silt which could generally be probed less than 1 inch using a 1/2 inch diameter soil probe. Relative compaction of the exposed foundation subgrade material was tested using a Troxler Moisture-Density gauge; an in-place density test 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 material observed today is currently suitable for support of the intended structure. GeoDesign recommends that any loose and saturated material be removed from the base of the footings prior to placement of concrete.
