(i Installation Records 0 Other Reviewed By: At PURPOSE of VISIT: GeoDesign representative, Ben Weinberg,was on-site part time at the request of Craig with DDS to observe the foundation subgrade for Lots 259 and 260. SUMMARY of OBSERVATIONS: LOT 259: Today, GeoDesign noted that DDS had excavated the foundation and crawl-space area for Lot 259. GeoDesign noted that the east side of the lot area had been over-excavated approximately 1 foot. The exposed foundation subgrade material generally consisted of a gray-brown silty SAND (f-m)with gravel (f-c)which could be probed less than 2 inches using a 1/2 inch diameter soil probe. Relative compaction of the exposed foundation subgrade material was tested using a Troxler 3430 Moisture-Density gauge. In-place density tests indicated that the exposed foundation subgrade for Lot 259 had been compacted to greater than 95% of its maximum dry density. GeoDesign notified Craig with DDS that the lot area was suitable for placement of structural backfill to bring the lot area to plan bottom of footing. LOT 60- Today, GeoDesign noted that DDS had excavated the foundation and crawl-space area for Lot 260. GeoDesign noted that the east side of the lot area had been over-excavated approximately 1 foot.The exposed foundation subgrade material for the east 3/4's of the lot area generally consisted of a gray-brown silty SAND (f-m)with gravel (f-c)which could be probed less than 2 inches using a 1/2 inch diameter soil probe. For the west 1/4 of the lot area,the foundation subgrade material consisted of a gray silty SAND which could be probed 6 inches to 1 foot using a 1/2 inch diameter soil probe; GeoDesign clearly marked the area with orange spray paint and notified Craig with DDS that we recommended removal of the loose material down to firm and unyielding underlying soil. Relative compaction of the exposed foundation subgrade material for the east 3/4's of the lot area was tested using a Troxler 3430 Moisture-Density gauge. In-place density tests indicated that the exposed foundation subgrade for Lot 260 had been compacted to greater than 95%of its maximum dry density. GeoDesign notified Craig with DDS that the east 3/4's of the lot area was suitable for placement of structural backfill to bring the lot area to plan bottom of footing. A summary of our observations and density tests can be found in the attached Figure 1, Nuclear Density Gauge Data, and Photo Log. 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
