GDI Project Polygon-130-05 Prepared By Ryan Rasanen
Project Name: River Terrace Northwest Date: 3/22/17
Location: Scholls Ferry Road and Roy Rogers Report# 163
Arrival:; 1315 Departure: 1345
Weather Sunny, 50's Permit#: TBA
Site Visit Requested By: Sam (Polygon) Met With(on site): Strauss Excavation, Sam
(phone)
Purpose: Evaluate Subgrade
Outstanding Issues: FR 51 (01/14/16) Lot 122 to 123 retaining wall
FR-136 (9/14) Low density pavement
wlldinq,10(lots 195—j96)subgrade
Upon arrival, I met with Strauss Excavation crew and was directed to areas indicated on attached site plan of
prepared foundation subgrade for building 10 lots 195 and 196. I observed the subgrade to primarily consist of
brown silt. One area, as shown on the site plan,appeared to be primarily rock fill consisting of 4"-0 crushed rock.
Strauss crew believed it to be structural fill placed and compacted by the earthwork contractor NEI. Using a Y2"
diameter steel foundation rod I probed the exposed subgrade. Subgrade appeared to be medium stiff to stiff and
dense respectively. I observed loose rock on the surface of the rock area; we recommend this layer to be compacted
prior to pouring. I also observed standing water and silt slough in footing areas;we recommend any standing water
and/or slough be removed prior to pouring.
Based on our observation and probing,the building foundation subgrade for lots 195 and 196 observed today and
indicated on the attached site plan have been prepared in general accordance with our geotechnical
recommendations.
