1 <br /> 1 <br /> APPENDIX A <br /> FIELD EXPLORATION AND LABORATORY TESTING <br /> ' Baywood Industrial <br /> Everett,Washington <br /> 1 On September 9,2019,we explored subsurface conditions at the site by performing 5 cone penetration tests(CPTs) <br /> at the site. The CPT locations were approximately determined in the field using by sighting and using GPS <br /> coordinates. The CPT locations are shown on Figure 2. <br /> In Situ Engineering, Inc., under subcontract to Terra Associates, Inc. performed the CPTs at locations selected by <br /> Terra Associates, Inc. The maximum depth the CPTs were advanced was 80 feet below the surface. The CPT <br /> ' consists of pushing an instrumented, approximately 1 1/2-inch diameter cone into the ground at a constant rate. <br /> During advancement,continuous measurements are made of the resistance to penetration of the cone and the friction <br /> of the outer surface of a sleeve. The cone is also equipped with a porous filter and a pressure transducer for <br /> ' measuring groundwater or pore water pressure generated. Pore pressure dissipation tests were completed at four of <br /> the CPT locations to determine groundwater depths. Measurements of tip and sleeve frictional resistance, pore <br /> pressure, and interpreted soil conditions and groundwater depths are summarized in graphical form on the CPT <br /> Logs attached in Appendix A. <br /> r <br /> I <br /> I <br /> I <br /> I <br /> Project No. T-8221 <br />
