Old Snelling Avenue Roadway Improvements <br />Arden Hills, Minnesota <br /> NTI Project No. 19.MSP09107.000 <br />Page 1 of 3 <br />1.0 INTRODUCTION <br />1.1 Site / Project Description <br />It is our understanding the project will consist of improvements to the existing Old Snelling Avenue <br />between County Road E and Snelling Avenue North in Arden Hills, Minnesota. <br />1.2 Scope of Services <br />The purpose of this factual report is to present a summary of our geotechnical exploration and provide <br />the soil conditions encountered at the project area. Our “scope of services” was limited to the <br />following: <br />1.Explore the project subsurface by means of seventeen (17) Standard Penetration Test (SPT) <br />borings extending to depths of approximately 14.5 feet below existing grade. <br />2.Conduct laboratory testing as requested by a representative of Short Elliott Hendrickson Inc. <br />(SEH). <br />3.Provide a factual geotechnical report with the results of our field and laboratory tests results. <br />2.0 EXPLORATION PROGRAM RESULTS <br />2.1 Exploration Scope <br />The field exploration was performed during a period of October 3 through 11, 2019 with the borings <br />advanced to depths of approximately 14.5 feet below the existing ground surface. Two (2) borings (SB- <br />16 and SB-17) were not completed at the requested of the client’s representative Short Elliot <br />Hendrickson Inc. (SEH) due to utility obstructions at the original boring locations. A representative of <br />SEH marked and surveyed the boring locations prior to mobilization. <br />The borings were performed by a two-person crew utilizing a CME 750 All Terrain Vehicle-mounted drill <br />rig. Samples were collected in general accordance with ASTM D 1586 “Standard Test Method for <br />Standard Penetration Testing (SPT) and Split-Barrel Sampling of Soils.” <br />The boreholes were backfilled with auger cuttings, or were abandoned using high solids bentonite or <br />neat cement grout as per appropriate local and state statutes. Minor settlement of the boreholes will <br />occur. Owner is responsible for final closure of the boreholes.
