The west 1/3 of the lot area <br /> consisted a gray to gray-brown GRAVEL with sand and silt that could be probed generally less than 3 inches. <br /> Relative compaction of the exposed foundation subgrade was tested using a Troxler Moisture-Density gauge; in-place <br /> density tests indicated that material had been compacted to greater than 95%of its maximum dry density as determined by <br /> a Modified Proctor analysis. <br /> It is the opinion of GeoDesign that exposed foundation subgrade observed today is currently suitable for support of the; <br /> intended structure. GeoDesign recommends that any surficially loose and saturated material that may be generated be <br /> removed from the base of foundation areas prior to the placement of concrete. <br /> Lots 149: <br /> Upon arrival, GeoDesign noted that DDS had completed excavation of the foundation and crawl space area for Lot 149. <br /> The lot area,which was previously covered with a temporary sales office, was over-excavated 1-2 feet below plan subgrade <br /> across most of the lot area. There were 3 internal areas where concrete pads had been installed which required <br /> over-excavation of approximately 3 feet below planned subgrade. The soil exposed at the base of the excavation generally <br /> consisted of a gray-brown silty SAND with gravel that could be probed less than 1 inch using a 1/2 inch diameter soil probe. <br /> Relative compaction of the exposed foundation subgrade soil was tested using a Troxler Moisture-Density gauge; in-place <br /> density tests indicated that the material had been compacted to greater than 95%of its maximum dry density as determined <br /> by a Modified Proctor analysis. GeoDesign notified the contractor that the excavation observed today is currently suitable <br /> for placement of backfill material. It is our understanding that the contractor intends to backfill the excavation with 2-inch <br /> clean crushed rock material compacted into a firm and unyielding mass over the next few days. <br /> A summary of our observations and density tests taken today can be found in the attached Figure 1 and Nuclear Density <br /> Gauge Data. The contractor was notified of our observations. <br /> 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 <br /> 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 <br /> 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 <br /> final upon review of the GeoDesign project manager,as indicated by initials in the"Reviewed By'section, <br /> 10700 Meridian Avenue North,Suite 402 I Seattle,WA 98133 I 206.838.9900 <br /> 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095 <br />
