FIELD REPORT <br />Project: Miller Residence Slope Stabilization <br />nELSon GEOTECHnicAL Client: Dennis & Chelsea Miller <br />ASSOCIATES, inc Location: 2702 — 59th Street SW <br />Everett, Washington <br />17311 1351h Ave. NE #A-500 Weather: Cloudy; 50s *F <br />Woodinville, WA 98072 <br />(425) 486-1669 FAX 481-2510 Purpose of Geotechnical Consultation and <br />105 Palouse Street Visit: Construction Monitoring <br />Wenatchee, WA 98801 <br />(509)665-7696 <br />NGA File: 13333B-22 <br />Date: 10/17/2023 <br />Report No: 4 <br />Page 1 of 2 <br />By: SAM <br />We visited the site today at the request of Pearson Drilling on behalf of the homeowners, to provide geotechnical consultation <br />services for the proposed slope stabilization project located at the above address in Everett, Washington. Upon arrival, we <br />met with Pearson Drilling to discuss project plans. <br />During our visit, we observed the installation of nine soldier piles. To drill each hole, the contractor used a 24-inch diameter <br />auger. Piles were placed in the prepared drill shafts with the corresponding lengths, per the approved plans. Very slight <br />groundwater seepage was observed in the drilled hole for pile 1 approximately 3.0- to 5.0-feet below the surface. No <br />groundwater seepage was observed in all other drilled holes. No significant sloughing was observed, and holes remained <br />open at depth. After completion of the drilling and beam installation for the day, the contractor pumped Portland cement <br />mixture into the drilled holes. The number of piles installed and depth of hole from the existing ground surface can be found <br />in Table 1 below in order each soldier pile was installed. <br />Table i <br />Pile Number <br />Approx. Depth of hole (feet) <br />Pile 1 <br />24 <br />Pile 9 <br />24 <br />Pile 10 <br />24.5 <br />Pile 11 <br />24.5 <br />Pile 12 <br />25 <br />Pile 19 <br />1 25.5 <br />Pile 18 1 <br />25 <br />We have been providing geotechnical consultation and construction monitoring services on a full-time basis. Our findings <br />and conclusions are based on specific observations made while on site. In our opinion, the soldier piles observed today <br />were installed correctly and in general accordance with project plans. We will continue to monitor the installation of the <br />shoring system. Additionally, temporary erosion control measures appeared to be performing adequately during our time <br />onsite. <br />Attachment: Site Plan <br />Distribution: <br />Signed: P.c44--) cqc <br />For Sammie McElwain <br />
