SUMMARY of OBSERVATIONS: Lots 162 and 163: Upon arrival, GeoDesign met with John with Polygon. Previously, GeoDesign noted that the exposed foundation subgrade for the east half of Lots 162 and 163 consisted of a dark brown sandy SILT with trace to minor organics and debris which could be probed 1 to 2.5 feet;GeoDesign recommended that up to 2 feet of material be over-excavated to expose underlying firm and unyielding material. Today, GeoDesign noted that the foundation excavation subcontractor had removed approximately 2 feet of material for the previously identified area for Lot 162. GeoDesign noted that the exposed subgrade material consisted of a dark brown sandy SILT with trace to minor organic and debris which could be penetrated 1 to 3 feet using a 1/2 inch diameter soil probe. GeoDesign recommended that the base of the foundation excavation be lined with a nonwoven filter fabric and backfilled with 2-inch clean crushed railroad ballast compacted into a firm and unyielding mass. GeoDesign also noted that the foundation subcontractor was in the process of removing 2 feet of material from the previously identified area for Lot 163. The material exposed of the base of the excavation consisted of similar material to that encountered for Lot 162. For both Lots 162 and 163, GeoDesign noted that the exposed subgrade material for over-excavated areas on the west side of the lots consisted of a brown-gray silty SAND with gravel which could be penetrated less than 2 inches using a 1/2 inch diameter soil probe. It is GeoDesign's understanding that these over-excavated areas will be backfilled with 2-inch clean crushed railroad ballast material.
