SUMMARY OF OBSERVATIONS: LOT 250: Previously, GeoDesign noted loose and saturated material which could be probed 1 to 1.5 feet along the northwest corner of the foundation area just outside of the perimeter footing. GeoDesign recommended that the material be removed down to firm and unyielding material and replaced with a clean crushed rock material. Today, GeoDesign noted that the loose material in the northwest corner had been over-excavated approximately 1.5 to 2.0 feet down to firm and unyielding material. GeoDesign noted that the loose material along the north side appeared to extend farther to the east,with some saturated material yielding underfoot. GeoDesign notified the client and contractor that the over-excavated area was currently suitable for placement of backfill material and recommended that the loose and saturated material which continued to the east be over-excavated down to firm and unyielding material and replaced with a clean crushed rock material. LOT 251: Previously, noted loose and saturated material which could be probed approximately 8-12 inches in the southeast corner of the foundation area and approximately 3 inches of surficially loose and saturated material along the west perimeter of"the foundation area. GeoDesign recommended that the material in these areas be removed down to firm and unyielding material and replaced with a clean crushed rock material. Today, GeoDesign noted that DDS had over-excavated/cleaned off the previously identified areas and backfilled the area with a clean angular crushed rock material tamped into a firm and unyielding mass. It is the opinion of GeoDesign that the exposed foundation subgrade for Lot 251 is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and saturated material that is generated be removed from the base of foundations prior to the placement of concrete. The client and contractor were notified of our observations and recommendations prior to our departure from the site today. 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
