El Site Plan(s) 0Density Test Summary l Signature: ^-- Attachments: ❑ Installation Records 0 Other Reviewed By: ' PURPOSE of VISIT:GeoDesign representative,Benjamin Weinberg,was on-site part time at the request of John Feltner with Polygon to observe the foundation subgrade from Lots 123 and 124. SUMMARY of OBSERVATIONS: Upon arrival, GeoDesign noted that the foundation excavation subcontractor was in the process of removing surficially loose and saturated material from the base of the foundation area for the east portion of Lot 124. GeoDesign noted that the exposed foundation subgrade consisted of a gray silty SAND(f-m)with gravel (f-c)which could be probed generally less than 3-4 inches. Relative compaction of the exposed foundation subgrade area was tested using a Troxler Moisture-Density gauge; in-place density tests indicated that the exposed 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 area observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and saturated material be removed from the base of the foundation areas prior to the placement of concrete. Lot 123: GeoDesign noted that the over-excavated area on the west side of Lot 123 had been backfilled with permeable ballast material compacted into a firm and unyielding mass. GeoDesign also noted that material was being stockpiled on the eastern portion of the foundation area,which was currently not ready for the foundation subgrade evaluation. The client and concrete contractor were notified of our observations prior to our departure from the site. A summary of our observations can be found in the attached Figure 1 and Nuclear Density Gauge Data.
