SUMMARY OF OBSERVATIONS: Lot 155: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 155. The exposed footing subgrade soil generally consisted of a gray-brown to brown silty SAND with gravel that could be probed generally less than 2 inches using a 1/2 inch diameter soil probe. Relative compaction of the footing subgrade soils was tested using a Troxler Moisture-Density gauge; in-place density tests indicated that 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 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 be generated be removed from the base of foundation areas prior to the placement of concrete. Lot 156: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 156.

A summary of observations and density tests taken 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 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 /P 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095
