SUMMARY OF OBSERVATIONS: Lot 201: Today, GeoDesign noted that DDS had completed backfilling the previously over-excavated area along the east end of the south perimeter foundation (30' L x 10'W x 0.5-1.5' D)with a 2-inch clean crushed rock material compacted into a firm and unyielding mass. Relative compaction of the gray-brown silty SAND with gravel subgrade was tested using a Troxler Moisture-Density Gauge; in-place density tests indicated that the soil 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 exposed foundation subgrade observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and saturated material that may develop be removed from the base of foundation areas prior to the placement of concrete. Foundations should not be poured on frozen ground; any soils loosened from frost-heave should be removed from the base of foundation areas prior to placement of concrete. A summary of our observations can be found in the attached Figure 1 and Nuclear Density Gauge Data. The contractor was notified of our observations prior to our departure from the site today. 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 I Seattle,WA 98133 I 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095 tJ Y
