Report 19 tele GEODESIGN= 702 s FIELD REPORT 77 Page 1 of 1 GDI Project: Polygon-164-03 Prepared By: Justin Juggert Project Name: River Terrace East No. 3 -Phase 2 Date: 3/30/21 Location: 16973 SW Friendly Ln,Tigard,OR Report#: 27 Arrival: 0945 Departure: 1015 Weather: Overcast, 40's Permit#: Site Visit Requested By: Adrian (Taylor Morrison) Met With (on site): Adrian (Phone) Purpose: Evaluate subgrade for Lots 265-269 Outstanding Issues: On arrival, Adrian (Taylor Morrison) informed me that crews had cut subgrade to finished elevations within Lots 265- 269, as shown on the attached site plan. I observed that crews had placed —1-2" of crushed rock over subgrade. I observed subgrade to consist of brown silt(excavation sidewalls). Using a Y2"foundation probe I evaluated the relative consistency of the subgrade through crushed rock section. Resulting penetrations indicated generally stiff subgrade conditions. Based on our observations and probing it is our opinion that the subgrade observed today, in areas observed today, has been prepared in general accordance with our geotechnical recommendations. Distribution: Attachments: Site Plan (1) Reviewed by: 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. Our work does not include supervision or direction of the contractor,the contractor's employees or agents. Our firm is not responsible for site safety. This field report is a DRAFT representation of our field observations,testing,and preliminary recommendations. The report can only be considered final upon review of the GeoDesign project manager,as indicated by initials in the"Reviewed By'section.

I was informed that base section was approx. 24in thick and consisted of recycled concrete sourced from Tigard Sand & Gravel. Compaction efforts were completed utilizing a large walk behind plate compactor. Using a Troxler 3430 nuclear density gauge, I evaluated the compaction of the fill and compared the results against a lab produce proctor value of 1 19.3pcf 14.3-precent optimum moisture content. Initial testing did not meet our compaction recommendations of 95%compaction of maximum dry density value. We recommended moisture conditioning the material and applying additional compaction efforts. After re- compaction efforts slab base section met our recommendations. I observed the pin resistance (number of blows on a %"diameter steel pin with a 6Ib hammer to drive the pin approx. 12in into the material) to indicated densely compacted material. Based on our observations, density testing, and pin resistance it is our opinion that the slab base section observed today, in areas observed today, has been prepared in general accordance with our geotechnical recommendations.
