SUMMARY of OBSERVATIONS: LOT 220: Today, GeoDesign noted that DDS had completed the excavation of the footing, crawl space, and crawl space drain for Lot 220 prior to our arrival on -site. Previously, GeoDesign noted that the Lot 220 area had been over -excavated —3-4 feet down to firm and unyielding ground (during removal of surcharge material) and brought back to plan grade with material compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. GeoDesign noted that the exposed foundation subgrade material consisted of a brown SAND (f-m) with silt which could generally be probed less than 1 inch using a 1/2 inch diameter soil probe. Relative compaction of the exposed foundation subgrade material was tested using a Troxler Moisture -Density gauge; an in -place density test indicated that the material had been compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. 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 ff� ' s prior to placement of concrete. K LOT 221: Today, GeoDesign noted that DDS had completed the excavation of the footing, crawl space, and crawl space drain for Lot 221 prior to our arrival on -site. Previously, GeoDesign noted that the Lot 221 area had been over -excavated —3-4 feet down to firm and unyielding ground (during removal of surcharge material) and brought back to plan grade with material compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis.

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. 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. 10700 Meridian Avenue North, Suite 402 1 Seattle, WA 98133 1 206.838.9900 2502 Jefferson Avenue I Tacoma, WA 98402 1 253.203.0095
