WISIDESIGM FIELD REPORT
Page 1 of 1
GDI Project: Polygon-1 13-05 Prepared By: Dan Boileau
Project Name: Roshak Ridge 1/15/2021
Location: SW Bull Mountain Road and SW Roy Report#: 187
Rogers Road, Tigard
Arrival: 1245 Departure: 1315
Weather: Overcast 50's Permit#: TBA
Site Visit Requested By: Adrian Adams (Taylor Morrison) Met With (on site): Adrian
Purpose: Observe lots 87-91 footing subgrade
Outstanding Issues: FR-186 1/14/21 Park Slope Failure
*RCSOVLED*
On arrival, I observed subgrade had been prepared to final elevations within Building 1 (Lots 87-91), as
indicated on the attached site plan. Adrian indicates water had been removed from footings and footing
subgrade had been over-excavated resulting in up to 12" crushed rock section. 3/"-0 crushed rock had been
placed in footing base and compacted. I used a %" diameter steel foundation probe to evaluate the consistency
of the subgrade base on side walls. Resistance to penetration indicates generally medium stiff to stiff
subgrade conditions. Resistance to penetration in granular pads indicates dense to very-dense conditions.
Rock was well keyed and firm under foot.
I observed standing water (-8-12") within spread footing excavations as shown on the attached site plan.
Probing through water indicates generally stiff subgrade conditions. We recommend water is removed and any
potential remaining slough and/or muck is removed from footing base prior to footing pour.
Based on observations and probing, footing subgrade and granular pads observed today and indicated on
attached site plan are being prepared in general accordance with our geotechnical recommendations provided
aforementioned recommendations are enacted.
