GeoDesign noted that the exposed foundation subgrade consisted of a gray to gray-brown silty SAND with gravel and concrete/asphalt. Penetration depths encountered across the west side of the lot area were generally less than 1 inch. GeoDesign noted that that the east 1/4 of the lot area required approximately 3.0 feet of over-excavation to expose firm and unyielding ground which could be probed less than 2 inches using a 1/2 inch diameter soil probe. GeoDesign notified the client and contractor that the excavation was currently suitable for placement of structural backfill material. LOT 273: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 273. Previously, GeoDesign observed the removal of unsuitable fill material from 8-10 feet below bottom of plan footing within the building area and replacement with structural fill material. Today, GeoDesign noted that exposed foundation subgrade material consisted of a gray-brown silty SAND with gravel which could generally be probed less than 2 inches using a 1/2 inch diameter soil probe. 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/or saturated material be removed from the base of the foundation area prior to the placement of concrete. A summary of our observations and density tests taken today 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 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 402 I Seattle,WA 98133 I 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 I 253.203.0095
