GeoDesign noted that the exposed mat foundation subgrade consisted of a gray-brown silty SAND <br /> with gravel that could generally be probed less than 1 inch using a 1/2 inch diameter soil probe. GeoDesign noted two <br /> areas along the west side of the mat foundation area that could be probed 1-3 feet using a 1/2 inch diameter soil probe; <br /> these areas were clearly identified with orange spray paint. We recommend that the loose material identified be removed <br /> down to firm and unyielding underlying soil and backfilled with a 2-inch clean crushed rock. <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. <br /> It is our understanding that foundation excavation subcontractor will over-excavate the identified areas beginning tomorrow. <br /> A summary of our observations 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 I 253.203.0095 <br />
