Site Visit Requested By: Tom (Polygon) Met With (on site): Tom (Polygon)
PurpEe: Lot 137-subgrade evaluation
Outstanding Issues: FR-136(9/14) Low density pavement
I arrived on site as arranged by Tom with Polygon Homes. The purpose of my site visit was to observe subgrade for
lot#137 as indicated on the attached site plan.
Upon arrival, I observed earthwork crew had completed finish grading for lot 137. The exposed subgrade generally
consists of brown silt(ML). Using ah-inch diameter steel foundation probe, I evaluated the relative consistency of
the subgrade. Based on probing,the subgrade appears medium stiff to stiff.
Based on our observation and probing, it is our opinion that the subgrade for lot#137 where observed today has
been prepared in general accordance with our geotechnical recommendations.
