SUMMARY of OBSERVATIONS: Lot 142: Upon arrival, GeoDesign noted that the foundation excavation subcontractor had completed excavation of the footing and crawl space area for Lot 142. GeoDesign noted that the exposed footing subgrade generally consisted of a gray and brown silty SAND (f-m) with gravel (f-c) which could generally be penetrated less than 2 inches using a 1/2 inch diameter soil probe. GeoDesign noted an area in the northwest corner of the lot area which exhibited yielding/pumping underfoot and could be probed approximately 6 inches to 1 foot. GeoDesign recommended that the area be over-excavated down to firm and unyielding underlying material, lined with a non-woven geotextile material, and backfilled with with structural fill material. The affected areas were clearly identified using orange spray paint. GeoDesign notified the subcontractor and client of our observations prior to our departure from the site today. Lot 143: Upon arrival, GeoDesign noted that the foundation excavation subcontractor had completed excavation of the footing and crawl space area for Lot 143. GeoDesign noted that the exposed footing subgrade generally consisted of a gray and brown silty SAND (f-m) with gravel (f-c) which could generally be penetrated less than 2 inches using a 1/2 inch diameter soil probe. GeoDesign noted an area on the west 1/3 of the lot area which could be probed approximately 6 inches to 1.5 foot. GeoDesign recommended that the area be over-excavated down to firm and unyielding underlying material, lined with a non-woven geotextile material, and backfilled with with structural fill material. The affected areas were clearly identified using orange spray paint. GeoDesign notified the subcontractor and client of our observations prior to our departure from the site today. A summary of our observations can be found in the attached Figure 1. John Feltner with Polygon was notified of our observations prior to our departure from the site. This report presents opinions formed as a result of our observatlon of activities relating to geotechnical engineering or environmental services.We rely on the contractor to complywith 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 prehrttinary recommendations.The report can onty be considered Bnal upon review of the GeoDesign project manager,as indicated by initials in the"Reviewed By"section. 10700 Meridian Avenue North,Suite 402 1 Seattle,WA 98133 1 206.838.9900 2502 Jefferson Avenue I Tacoma,WA 98402 1 253.203.0095
