SUMMARY of OBSERVATIONS: LOT 268: Previously, GeoDesign identified unsuitable fill material for Lot 268 which required removal and replacement with structural fill. GeoDesign noted that the unsuitable material had been removed down to approximately 6 feet below plan bottom of footing and replaced with structural fill material compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. Today, GeoDesign noted that DDS had completed grading of the foundation and crawl space for the lot area. GeoDesign noted that the exposed foundation subgrade consisted of a gray-brown silty SAND with gravel which could be probed less than 3 inches using a 1/2 inch diameter soil probe and a thin layer of 2-inch clean crushed railroad ballast in the northeast corner. It is the opinion of GeoDesign that the exposed foundation observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the foundation area prior to the placement of concrete. LOT 269: Previously, GeoDesign identified unsuitable fill material for Lot 269 which required removal and replacement with structural fill. GeoDesign noted that the unsuitable material had been removed down to approximately 6 feet below plan bottom of footing and replaced with structural fill material compacted to greater than 95% of its maximum dry density as determined by a Modified Proctor analysis. Today, GeoDesign noted that DDS had completed grading of the foundation and crawl space for the lot area. GeoDesign noted that the exposed foundation subgrade consisted of a gray-brown silty SAND with gravel which could be probed less than 3 inches using a 1/2 inch diameter soil probe. It is the opinion of GeoDesign that the exposed foundation observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and/or saturated material be removed from the base of the foundation area prior to the placement of concrete. LOT 258: Previously, GeoDesign noted that DDS had excavated the Lot,258 area down to firm and unyielding material which required over-excavation of approximately 1 foot below plan bottom of footing. Today, GeoDesign noted that DDS had completed backfilling the lot area with approximately 1.5 feet of 2-inch clean crushed railroad ballast material compacted compacted into a firm and unyielding mass. It is the opinion of GeoDesign that the exposed foundation observed today is currently suitable for support of the intended structure. A summary of our observations can be found in the attached 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 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 402 I Seattle,WA 98133 I 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095
