Project Name: Roshak Ridge 07/19/2019
Location: SW Bull Mountain Road and SW Roy Rogers Report#: 1 53
Road,Tigard ;
Arrival: 1000 Departure 1 130
Weather: i Sunny, 80's Permit#: TBA
Site Visit Requested By: Tony(Polygon): Lot 43;Toby Met With (on
site): Tony, Toby (via phone)
(Polygon): Building 6 (Lots 112 -
116)
Purpose; ; Evaluate Lot 43 and Building 6 (lots 112-116) Subgrade
Outstanding Issues: 1FR-146 (06/05/2019) Soft wall subgrade
Upon arrival, I observed the excavation crew had excavated to the approximate planned subgrade elevation on lot
43 (see site plan). The subgrade appeared to consist of brown silt. Using a %2" diameter steel foundation probe, I
evaluated the relative consistency of the subgrade. Probe resistance indicated generally stiff to very stiff conditions.
I observed the excavation crew had excavated to the approximate planned subgrade elevation for Building 6 (lots
112 - 116). The subgrade appeared to consist of brown silt. Using a1/2" diameter steel foundation probe, I evaluated
the relative consistency of the subgrade. Probe resistance indicated generally stiff to very stiff conditions.
Based on our observations and probing, it is our opinion that subgrade observed today has been prepared in general
accordance with our geotechnical recommendations.
