FIELD REPORT NELSON Project: Fox Residence File No.: 8592B13 GEOTECIINICAL Client: Logan Fox Date: 4/10/2013 ASSOCIATES, INC Location: 4626 Harbor Lane Report No: 03 Everett, WA 17311 135"' Ave. NE NA-500 Weather: Overcast/Showers, 50's page: 1 of 2 Woodinville, WA 98072 Purpose of (425)486-1669FAX481-2510 Visit: Construction Monitoring By:LSB/JPH We visited the site today at the request of Logan Fox to observe and evaluate construction activities associated with the Ultra Block wall at the residence located at 4626 Harbor Lane, Everett, WA. Upon arrival, we met with Brian with Ponderosa. We observed that they had began to place the Ultra Blocks within the northern portion of the wall as shown on the attached site plan. We observed that the wall foundation drain consisting of a 4-inch perforated PVC pipe wrapped in drain rock and filter fabric had been placed behind the base of the wall blocks. The roof drain tightline pipe consisting of a 4-inch solid PVC pipe was also placed behind the wall on top of the wall footing drain. These drains then daylighted through the wall in between the noiihern and soulhcm sections of the wall. These pipes were sleeved with heavy duty sewer pipe whcr^ they will be under the wall and backfilled with 5/8-inch minus crushed rock. The base block for the southern wall will be placed on the compacted crushed rock above the pipes. The pipes will be directed to the drywell to the southwest of the wall at it 2 percent grade. An approximately 12-in layer of 2-inch washed drain rock was placed behind the completed blocks. Brian informed us that they would continue placing the base blocks for the southern portion of the wall. We have been providing monitoring services on a part-time basis only. Our findings and conclusions are based on construction activities observed while on site. Based on our part-time observations in the field, communications with the contractor, our understanding of this site and project plans, and provided that the contractor used consistent materials and methods while we were present and not present at the site, it is our opinion that the Ultra Block wall is being constructed in accordance with the plans and our recommendations. n Attachment: Site Plan Signed: Distribution:
