GDI Project: Polygon-122-04 Prepared By: Kylean Gunhus
Project Name: Polygon at Bull Mountain Date: 11/30/2015
Location: 15075 SW Danube Dr.Tigard, OR Report#: 52.2
Arrival: 0915 Departure: 1015
Weather: Cloudy, 20's Permit#: MST2015-0185
Site Visit Requested By: Jeff Dickson w/ NEI Met With (on site): NEI and KeyWest Crews
Purpose: Evaluate Lot 8 Subgrade
Outstanding Issues: FR40 (11/6) Low densities for retaining wall backfill *PARTIALLY RESOLVED FR41* ,._...
FR46 (11/18) Low densities for retaining wall backfill at top of wall
While onsite for other earthwork activities, I observed foundation subgrades as requested by Jason Canfield with
Polygon.
Lot 8
I observed that crew members had prepared the house foundation subgrade on lot 8. The footings for lot 8 had
been formed and crews were in the process of placing rebar at the time of my visit. Subgrade consisted of brown silt
covered with 1 to 2 inches of compacted crushed rock as leveling course. Using a1/2" diameter footing probe, I
probed through the crushed rock to evaluate the subgrade. Penetrations ranged from 1 to 4 inches. Based on
penetration resistance, the subgrade appeared stiff.
Based on observations and probing, the foundation subgrade for the house on lot 8 has been prepared in
accordance with our geotechnical recommendations.
