Today, GeoDesign noted that DDS had completed backfilling the over-excavated east 2/3rd's of the lot area with a cement treated soil which had been mixed and spread using the bucket of an excavator and compacted into a firm and unyielding mass using a smooth-drum vibratory roller. Penetration depths encountered for the exposed backfill material were generally less than 2 inches. It is the opinion of GeoDesign that the exposed foundation subgrade for Lot 231 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 footing area prior to the placement of concrete. LOT 232: Previously, GeoDesign noted that Lot 232 required approximately 1.5 to 2.0 feet of over-excavation for the center 1/3 of the lot area to expose a firm and unyielding material which could be probed less than 2 inches using a 1/2 inch diameter soil probe. Today, GeoDesign noted that DDS had completed backfilling the over-excavated center 1/3 of the lot area with a cement treated soil which had been mixed and spread using the bucket of an excavator and compacted into a firm and unyielding mass using a smooth-drum vibratory roller. Penetration depths encountered for the exposed backfill material were generally less than 2 inches. It is the opinion of GeoDesign that the exposed foundation subgrade for Lot 232 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 footing 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 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
