Upon arrival, GeoDesign spoke with John Feltner. SUMMARY of OBSERVATIONS: Lot 164: Upon arrival, GeoDesign noted that the foundation excavation subcontractor had completed excavation of the footing and crawl space area for Lot 164. GeoDesign noted that the exposed footing subgrade for Lot 164 generally consisted of a gray and brown silty SAND (f-m) with gravel (f-c) which could be penetrated generally less than 4 inches. GeoDesign noted an approximately 15 feet long section in the north corner of the foundation area which could be probed 1 to 1.5 feet and recommended that the material be over-excavated down to firm and unyielding material and be replaced with a structural fill material. Relative compaction of the exposed footing subgrade area was tested using a Troxler 3430 Moisture-Density Gauge. In-place density tests indicated that the exposed foundation subgrade materials had been compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. With the exception of the previously mentioned area, it is GeoDesign's opinion that the exposed footing 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 footing areas prior to the placement of concrete. Lot 165: Upon arrival, GeoDesign noted that the foundation excavation subcontractor had completed excavation of the footing and crawl space area for Lot 165. GeoDesign noted that the exposed footing subgrade material for Lot 165 consisted of a gray silty SAND (f-m) with gravel (f-c) and gray-brown SAND (f-m)with silt which could generally be probed less than 3 inches. In-place density tests taken on the exposed footing subgrade materials indicated that the materials had been compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. It is GeoDesign's opinion that the exposed footing 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 footing areas prior to the placement of concrete.
