SUMMARY of OBSERVATIONS: Lot 123: Previously, GeoDesign had identified an area on the west 1/4 to 1/3 of Lot 123 which would require over-excavation and replacement with permeable ballast material. GeoDesign previously observed that the area had been over-excavated 12 to 18 inches, lined with a geotextile material,and backfilled with permeable ballast material which had been compacted into a firm and unyielding mass. Today, GeoDesign observed the exposed foundation subgrade for the east 2/3 of Lot 123. The exposed foundation subgrade consisted of a gray silty SAND(f)with gravel(f-c)which could be penetrated less than 4 inches using 1/2 inch diameter soil probe. Relative compaction of the exposed foundation subgrade material was tested using Troxler Moisture-Density gauge. In-place density tests indicated that the material had been compacted to greater than 95%of its maximum dry density as determined by a Modified Proctor analysis. It is GeoDesign's opinion that the exposed foundation subgrade area observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose or saturated material be removed from the base of the foundation prior to the placement of concrete. A summary of our observations can be found in the attached Figure 1 and Nuclear Density Gauge Data. The client and concrete contractor were notified of our observations via email prior to our departure from the site. 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 irrexpectiye 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 7- _
