Report (3) r2c9 - doz/2 GEODESIGNk 74/323 /('? 1 FIELD REPORT Page 1 of 2 GDI Project: Polygon-1 13-05 Prepared By: Sam Freeman Project Name: Roshak Ridge 8/25/2020 Location: SW Bull Mountain Road and SW Roy Report#: 178 Rogers Road, Tigard Arrival: 0745 Departure: 0830 Weather: Sunny, 60s Permit#: MST201 9-002 1 0 MST2019-00076 Site Visit Requested By: Adrian Adams (Taylor Morrison) Met With (on site): Adrian, Curtis Heintz crew Purpose: Observe subgrade, building 13 Outstanding Issues: I arrived on site and met with Adrian (Taylor Morrison). I was directed to the location of building 13 (lots 72 - 76) where crews had prepared subgrade for the building slab (see attached site plan). I observed subgrade to consist of brown silt with trace gravel and sand. Resistance to penetration with%" diameter steel foundation probe indicates very stiff to hard conditions. While on site, Adrian asked me to observe backfill for sewer trenches inside the building. I was informed by the Curtis Heintz Excavating Inc. crew that approximately 12"of 1"-0 crushed recycled concrete had been placed in two lifts and compacted via large vibratory plate compactor. I observed the compacted recycled concrete to be well- keyed and firm under foot. Resistance to penetration with W' diameter steel foundation probe indicates very dense conditions. Based on our observations, probing, and conversation with the contractor, it is our opinion that the subgrade and shallow trench backfill observed today, as indicated on the attached site plan, has been prepared in general accordance with our geotechnical recommendations. Distribution: Attachments: Photo (1); 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.
