Purpose: Observe subgrade for lot 206, 207 & 208
Outstanding Issues: FR 227(061022) Lot 206 needs more analysis regarding its stability
Upon my arrival, I noticed that the contractor has completed excavation of lots 206, 207 & 208 to their grade
levels. On lots 207 & 208, the exposed subgrade was consisted of silt with gravel and cobbles. I used %"
diameter steel level, T-probe, to evaluate the subgrade. The subgrade had stiff to very stiff consistency based
on its resistance to probe's penetration.
On Lot 206, I noticed that the contractor excavated the lot at about 2' from existing retaining wall and cut 2'
to 5' of engineering fill behind the wall (please see the attached sketch and plan). The exposed subgrade was
consisted of either 3/4"-0" gravel or silt with gravels and cobbles. Based on its resistance to probe's penetration,
gravel was dense, and silt was stiff. After speaking with Shawn, NV5's project manager, the contractor was
informed that we need to analysis the situation as lot was located to close to the wall.
Based on our observations, it is our opinion that subgrade for 207 & 208 observed today, as indicated on the
attached site plan, has been prepared in general accordance with our geotechnical recommendations but lot
206 needs stability analysis.
