Attachments: ❑ Installation Records ❑ Other Reviewed By: RL PURPOSE of VISIT: GeoDesign representative, Ben Weinberg, was on-site part time at the request of John Feltner with Polygon to observe foundation subgrade for Lots 208 and 209. SUMMARY of OBSERVATIONS: LOT 208: Today, GeoDesign noted that DDS had completed excavation of the footing, crawl space, and crawl space drain for Lot 208. Previously, GeoDesign noted that BDZ and Northwest Construction had over-excavated the lot area down to firm and unyielding soil (-4-5 feet) and backfilled the lot area with an imported gray silty SAND (f-m)with gravel (f-c)which was compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. GeoDesign noted that the exposed foundation subgrade consisted of the previously mentioned gray silty SAND with gravel which could generally be probed less than 1 inch using a 1/2 inch diameter soil probe. It is the opinion of GeoDesign that the exposed foundation subgrade material observed today is currently suitable for support of the intended structure. GeoDesign recommends that any loose and saturated material be removed from the base of the footings prior to placement of concrete. LOT 209: Today, GeoDesign noted that DDS had completed excavation of the footing, crawl space, and crawl space drain for Lot 209. Previously, GeoDesign noted that BDZ and Northwest Construction had over-excavated the lot area down to firm and unyielding soil (-4 feet) and backfilled the lot area with an imported gray silty SAND (f-m)with gravel (f-c)which was compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis.

A summary of our observations can be found in the attached Figure 1. 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 indude 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. 10700 Meridian Avenue North,Suite 402 I Seattle,WA 98133 I 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095
