Weather: Clear, 70's Permit#: MST2018-00336
Site Visit Requested By: Toby(Polygon Homes) Met With (on site): Toby(via cell)
Purpose: Evaluate Lot 4 Sub.rade
Outstanding Issues:
I observed contractor had excavated lot 4 to finished subgrade elevation and had placed 1 to 2 inches of recycled
crushed concrete over the subgrade. Subgrade soil appeared to consist of light brown silt. I used a Y2 inch diameter
"T" probe to evaluate relative consistency of the subgrade,which was observed to be stiff to medium stiff based on
resistance to penetration of the probe.
Based on our observations and testing, it is our opinion that lot 4 subgrade observed today has being prepared in
general accordance with our geotechnical recommendations.
