SUMMARY of OBSERVATIONS: Lot 107: Upon arrival,GeoDesign noted that foundation excavation subcontractor had finished digging the footing and crawl space prior to our arrival on-site. GeoDesign noted that the exposed foundation subgrade generally consisted of a gray-brown silty SAND(f-m) with gravel (f-c)which could be penetrated less than 2 inches using a 1/2 inch diameter soil probe under the full weight of the user;in-place density tests taken on the north, east, and south side indicated that the 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 the exposed foundation subgrade is currently suitable for support of the intended load. GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the footings prior to the placement of concrete. Lot 111: GeoDesign noted that foundation excavation subcontractor had finished digging the footing and crawl space using.

GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the footings prior to the placement of concrete. Lot 110: GeoDesign noted that the foundation excavation subcontractor had excavated approximately 50%of the footing and crawl drain area using a Case CX130 excavator and a grade blade. GeoDesign intends to evaluate the footing area after its completion tomorrow. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1. GeoDesign notified the concrete subcontractor of our observations prior to leaving the site. 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 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 I Seattle,WA 98133 I 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095
