Report 17977- 5u-f AO - • p • GEODESIGNV 9(.4„, Z2/ 7_00010FIELD REPORT Page l of 1 GDI Project: Polygon-151-04 Prepared By: Bret Moskal Project Name: River Terrace East - Multifamily Date: 2/6/18 Location: 13240 SW Roy Rogers Rd., Tigard Report#: 28 Arrival: 1115 Departure: 1150 Weather: Overcast, 40's Permit#: TBA Site Visit Requested By: Sam (Polygon) Met With (on site): Sam (Via Phone) Purpose: Evaluate Building B footing subgrade Outstanding Issues: FR-26 (12/22)Soft soil remains-pond Upon arrival, I observed the earthwork crew was in the process of excavating footings noted on attached site plan. At time of arrival I observed that earthwork crew had placed approx. 2"to 3"of un-compacted %" minus crushed rock material on the surface of native subgrade (light brown silt and clay). Using a1/2"diameter steel foundation rod I probed the subgrade. Probing indicted stiff to very stiff subgrade. I observed an area, noted on attached site plan, of free standing water on the surface of observed footing subgrade, Recommend that this area be de-watered and covered with gravel to protect subgrade from disturbance during wet condition Based on observations and probing, it is our opinion that buildings B subgrade observed today(contingent on following with recommendation noted above), have been prepared in general accordance with our geotechnical recommendations. Distribution: Attachments: Site Plan (1); Reviewed by: SMD This report presents opinions formed as a result of our observation of activities relating to geotechnical engineering or environmental services.We rely on the contractor to comply with the plans and specifications throughout the duration of the project irrespective of the presence of our representative.
