Attachments: m Site Plan(s) © Density Test Summary Signature: _ 0 Installation Records 0 Other Reviewed By: PURPOSE of VISIT: GeoDesign representative, Benjamin Weinberg,was on-site at the request of John Feltner with Polygon to observe foundation subgrade for Lots 129 and 128. SUMMARY of OBSERVATIONS: Lot 129: Upon arrival at approximately 8:00 AM, GeoDesign noted that the foundation excavation subcontractor had finished digging the footing and crawl space area for Lot 129 and that the excavation was currently filled with approximately 3-4 inches of water. GeoDesign notified John with Polygon that the foundation area would need to be dewatered prior to evaluation of the foundation subgrade. GeoDesign departed the site at approximately 8:15 AM and returned at 6:15 PM. After returning, GeoDesign noted that the foundation excavation area had been dewatered,with scattered puddles with less than 2 inches of water. The exposed foundation subgrade consisted of a gray silty SAND (f-m)with gravel (f-c)which was evaluated using a 1/2 inch diameter soil probe and a Troxler Moisture-Density gauge. Penetration depths encountered were generally less than 2 inches and in-place density tests indicated that the exposed foundation subgrade 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 suitable for support of the intended structure and recommends that any surficially loose and saturated material be removed from the base of the foundation prior to the placement of concrete. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1. Lot 128: Upon return to the site, GeoDesign noted that the foundation excavation subcontractor had excavated approximately 80% of the foundation and crawl space area for Lot 128. GeoDesign noted that the exposed foundation subgrade generally consisted of a gray silty SAND(f-m)with gravel (f-c)which could be penetrated less than 2 inches using a 1/2 inch diameter soil probe; in-place density tests taken on the west,south, and east 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 observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and saturated material be removed from the base of the foundation prior to the placement of concrete. A summary of our observations and density tests taken today can be found in the attached Nuclear Density Gauge Data and Figure 1. 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 indude 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 q2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095
