El Site Plan(s) m Density Test Summary Signature: Attachments: ❑ Installation Records 0 Other Reviewed By: RZ PURPOSE of VISIT: GeoDesign representative, Ben Weinberg,was on-site at the request of Eddy Stevens with Polygon to observe foundation subgrade for Lot 108. SUMMARY of OBSERVATIONS: Lot 108: Upon arrival, GeoDesign noted that foundation excavation subcontractor had finished digging approximately 90%of the footing and crawl space using a Case CX130 excavator and grade blade. GeoDesign noted that the exposed foundation subgrade generally consisted of a brown silty SAND(f-m)with gravel (f-c)which could be penetrated less than 2 inches using a 1/2 inch diameter soil probe under the full weight of the user; in-place density tests taken on the north, east,and south side 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 exposed foundation subgrade is currently suitable for support of the intended load. GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the footings prior to the placement of concrete. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1.
