PURPOSE of VISIT: GeoDesign representative, Ben Weinberg, was on-site part time at the request of Craig with DDS to observe foundation subgrade for Lots 207, 218, and 219. SUMMARY OF OBSERVATIONS: LOT 207: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 207. Previously, GeoDesign noted that BDZ/Northwest Construction removed-3-4 feet of unsuitable fill material down to firm and unyielding soil and replaced it with structural fill material. GeoDesign noted that the exposed foundation subgrade consisted of a gray silty SAND (f-m)with gravel (f-c)which could be probed less than 2 inches using a 1/2 inch diameter soil probe. It is the opinion of GeoDesign that the exposed foundation subgrade observed today is currently suitable for support of the intended structure. GeoDesign recommends that any surficially loose and saturated material that may build up under foundation areas be removed prior to the placement of concrete. LOT 218: Today, GeoDesign noted that DDS had completed excavation of the footing and crawl space area for Lot 218. Previously, GeoDesign noted that BDZ/Northwest Construction removed -3-4 feet of unsuitable fill material down to firm and unyielding soil and replaced it with structural fill material. GeoDesign noted that the exposed foundation subgrade consisted of a gray to brown silty SAND (f-m)with gravel (f-c)which could generally be probed 2-4 inches using a 1/2 inch diameter soil probe. GeoDesign noted the south perimeter footing area for Lot 218 was submerged during our site visit; GeoDesign noted that the submerged material could be probed 1 to 1.5 feet using a 1/2 inch diameter soil probe. GeoDesign recommended that this area be dewatered, loose soil removed down to firm and unyielding material, and area backfilled with a structural fill material. The area was delineated using white spray paint. It is GeoDesign's understanding that the area will be over-excavated tomorrow.
