IReviewed By: � PURPOSE of VISIT: GeoDesign representative, Ben Weinberg, was on-site part time at the request of Craig with DDS to observe foundation subgrade for Lot 279. SUMMARY OF OBSERVATIONS: Lot 279: Upon arrival, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 279. GeoDesign noted that the footing subgrade area was covered in 2-3 inches of water, except for the southwest corner of the building area. Craig with DDS notified us of a soft area in the southeast corner of the footing and crawl-space area. The approximately 25 feet long and 12 feet wide area consisted of saturated gray silty SAND with gravel which could be probed up to 4.5 feet using a steel rod under and exhibited significant pumping/yielding underfoot. GeoDesign notified the client and contractor that the area observed was not suitable for support of the intended structure and recommended that the material be removed down to firm and unyielding soil and backfilled with structural fill material. We delineated the area and clearly marked the outline using orange spray paint prior to departing the site. With the exception of the southeast corner of the building, GeoDesign noted that the exposed footing subgrade generally consisted of a gray silty SAND (f-m)with gravel (f-c) (covered with —2 inches of loose and saturated material)which could be probed less than 2 inches using a 1/2 inch diameter soil probe. We notified the client and contractor that the water and loose material would need to be removed from the footing area, but that the underlying soil was suitable for support of the intended structure. It is our understanding that the contractor intends on over-excavating and replacing the soft area tomorrow. 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
