REPORT OF GEOTECHNICAL EXPLORATION AND REVIEW <br /> PROPOSED CRYSTAL BAY BUSINESS CENTER <br /> ORONO, MINNESOTA <br /> AET PROJECT NO. 22-00012 <br /> 1.0 INTRODUCTION <br /> You have authorized American Engineering Testing, Inc. (AET) to conduct a subsurface <br /> exploration and provide geotechnical engineering recommendations for this project. This report <br /> presents the field information we obtained during previous geotechnical explorations on this site, <br /> our geotechnical laboratory results, and our engineering recommendations for earthwork and <br /> foundations. <br /> To protect you, AET, and the public, we authorize use of opinions and recommendations in this <br /> report only by you and your project team for this specific project. Contact us if other uses are <br /> intended. Even though this report is not intended to provide sufficient information to accurately <br /> determine quantities and locations of particular materials, we recommend that your potential <br /> contractors be advised of the report availability. <br /> 2.0 SCOPE OF SERVICES <br /> Our scope of services for this project, as outlined in our proposal, was limited to the following <br /> elements <br /> • Drill and sample 28 Standard Penetration test (SPT) borings in accordance with ASTM: <br /> D1586, to depths of 10 feet to 20 feet; one of these borings (EP-8) was not drilled <br /> because we could not access that location in the storage yard. In addition to the SPT <br /> borings, drill seven hand auger borings inside the existing buildings and sample with a <br /> manually-operated 89 pound hammer, each to a depth of 4.5 feet. <br /> - Of the 34 borings that we drilled, 25 were drilled under environmental protocol for <br /> purposes of environmental screening by your environmental consultant, Liesch <br /> Associates, Inc. The borings that we drilled under environmental protocol are <br /> designated with an "EP" on the attached logs. The borings that were not drilled under <br /> Page 1 of 28 <br />
