SUMMARY of OBSERVATIONS: Lot 112: GeoDesign noted that the foundation subcontractor had excavated the footing and crawl space areas for Lot 112 prior to our arrival on-site. GeoDesign noted that the exposed footing subgrade consisted of a brown-gray silty SAND (f-m) with gravel (f-c) that had been exposed using a grade blade. The exposed foundation subgrade was evaluated using a 1/2 inch diameter soil probe and a Troxler Moisture-Density gauge. Penetration depths encountered ranged from 1 to 2 inches and in-place density tests indicated that the exposed foundation subgrade material had been compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1. It is the opinion of GeoDesign that the exposed foundation subgrade observed today was currently suitable for support of the intended foundation load. GeoDesign recommends that any loose and saturated material be removed from the base of the foundation prior to the placement of concrete. Lot 113: GeoDesign noted that the foundation subcontractor had excavated the footing and crawl space areas for Lot 113 prior to our arrival using a Komatsu PC120 excavator with a grade blade. GeoDesign noted that the exposed footing subgrade consisted of a brown-gray silty SAND (f-m) with gravel (f-c). The exposed foundation subgrade was evaluated using a 1/2 inch diameter soil probe and a Troxler Moisture-Density gauge. Penetration depths encountered ranged from 1 to 2 inches and in-place density tests indicated that the exposed foundation subgrade material had been compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1. It is the opinion of GeoDesign that the exposed foundation subgrade observed today was currently suitable for support of the intended foundation load. GeoDesign recommends that any loose and saturated material be removed from the base of the foundation prior to the placement of concrete. 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 aur 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 210 1 Seattle,WA 98133 1 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 1 253.203.0095
