GDI Project 1 Polygon-12204 Prepared By Bret Moskal Project Name: Polygon at Bull Mountain Date: l 4/24/17 Location: 1 15290 SW Seine Dr ,Tigard, Report#: 162 Oregon Arrival: 11230 Departure 1245 1. Weather: Rain, 40's Permit#: i MST2016 00253 Site Visit Requested By: Ken (Polygon) Met With (on site): Ken, Marco (Frank Excavating) Purpose: Observe lot 26 subgrade and base rock Outstanding Issues: Upon arrival I met with Ken and was directed to lot 26 where I was informed contractor(Frank Excavating) had prepared footing subgrade. Contractor had placed approx,2"to 3"of recycled concrete on the surface of structural fill subgrade. Compaction efforts were done utilizing a small walk behind plate compactor. Using a W'diameter steel foundation rod I probed the footing base rock. Probing indicated dense to medium dense base rock(respectfully depending on thickness of rock section probed). I observed the subgrade by probing through the base rock along with probing the side walls of the excavation. Probing indicated stiff subgrade. I observed that the base rock was saturated with varying amounts of standing water on the surface. Recommended that crew de-water this area before pouring footings. pass I observed a drainage trench that is to Ge underneath continuous footing on the east side of the building within lot 26 . I was informed that crew would place drain rock and perforated pipe within trench in non-structural areas.Then, place recycled concrete with "hard pipe"within structural areas (directly under footing).We recommend keeping pipe out from underneath footing where possible. Based on our observations and probing, areas observed subgrade and base rock observed today within lot 26 and indicated on attached site plan has been prepared in general accordance with our geotechnical recommendations, contingent on the de-water of the base rock noted above.. 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.Our work does not Include supervision or direction of the contractor,the contractor's employees or agents.
