SUMMARY of OBSERVATIONS: LOT 230: Today, GeoDesign noted that DDS had completed excavation of the foundation and crawl space area for Lot 230. The exposed foundation subgrade material consisted of a gray-brown silty SAND (f-m)with gravel (f-c)which could generally be probed less than 2 inches using a 1/2 inch diameter soil probe. Relative compaction of the exposed foundation subgrade material was tested using a Troxler Moisture-Density gauge; in-place density tests 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 foundation subgrade 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 foundation prior to the placement of concrete. LOT 274: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 274. Previously, GeoDesign observed the removal of unsuitable fill material from 8-10 feet below bottom of plan footing within the building area and replacement with structural fill material. Today, GeoDesign noted that exposed foundation subgrade material consisted of a gray-brown silty SAND with gravel which could generally be probed less than 1 inch using a 1/2 inch diameter soil probe. It is the opinion of GeoDesign that the exposed foundation subgrade observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the foundation area prior to the placement of concrete. LOT 275: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 275. Previously, GeoDesign observed the removal of unsuitable fill material from 8-10 feet below bottom of plan footing within the building area and replacement with structural fill material. Today, GeoDesign noted that exposed foundation subgrade material consisted of a gray-brown silty SAND with gravel which could generally be probed less than 1 inch using a 1/2 inch diameter soil probe. It is the opinion of GeoDesign that the exposed foundation subgrade observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the foundation area prior to the placement of concrete.
