SUMMARY of OBSERVATIONS: Lot 226: Previously, GeoDesign identified material along the north and east side of Lot 226 which could be probed 6 inches to 1 foot and which was compacted to less than 95%of its maximum dry density as determined by a Modified Proctor analysis (maximum dry density). Today, GeoDesign noted that DDS had over-excavated the previously identified areas down to a gray to gray-brown silty SAND (f-m)with gravel (f-c)which could be probed less than 1 inch using a 1/2 inch diameter soil probe. Relative compaction of the over-excavated footing 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. Craig with DDS stated that the over-excavated areas would be backfilled with a crushed rock or recycled concrete material later this week. GeoDesign notified the contractor that the over-excavated areas were currently suitable to place backfill material. Lot 236: Upon arrival, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 236. Craig with DDS over-excavated the east 1/3 of lot area approximately 6 inches due the presence of loose saturated material. DDS also over-excavated an approximately 15 feet long x 5 feet wide x 2.5 feet deep section at the west end of the south side of the lot. GeoDesign noted that the exposed foundation subgrade consisted of a gray to 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. In-place density tests indicated that exposed foundation subgrade material had been compacted to greater than 95%of its maximum dry density. Craig with DDS stated that the over-excavated areas would be backfilled with a crushed rock or recycled concrete material later this week.GeoDesign notified the contractor that the over-excavated areas were currently suitable to place backfill material. Lot 237: Upon arrival,GeoDesign noted that DDS had was in the process of excavating the footing and crawl space area for Lot 237. GeoDesign noted that the exposed foundation subgrade consisted of a gray to dark 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.
