Today, GeoDesign noted that the foundation <br /> excavation subcontractor had completed backfilling the over-excavated areas with a 2-inch clean crushed rock material <br /> compacted into a firm and unyielding mass. <br /> Relative compaction of the remaining exposed foundation subgrade soil was tested using a Troxler Moisture-Density gauge; <br /> an in-place density test confirmed that the material had been compacted to greater than 95%of its maximum dry density as <br /> determined by 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 be removed from the base of <br /> foundation areas prior to the placement of concrete. <br /> Lot 216: <br /> Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 216. The exposed <br /> footing subgrade soil generally consisted of a gray-brown silty AND with gravel that could probed less than 2 inches using <br /> a 1/2 inch diameter soil probe. Relative compaction of the footing subgrade soils was tested using a Troxler <br /> Moisture-Density gauge; in-place density tests indicated that material had been compacted to greater than 95% of its <br /> maximum dry density as determined by 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 be removed from the base of <br /> foundation areas prior to the placement of concrete. <br /> A summary of observations and density tests taken can be found in the attached Figure 1 and Nuclear Density Gauge Data. <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 98402.1 253.203.0095 <br /> 35 <br />
