SPC ENGINEERING & TESTING,INC. <br /> 4764 EUROPA TRAIL <br /> HUGO,MN 55038 <br /> 651.653.6349 <br /> June 17, 2008 <br /> Project 2008.053 <br /> Carlson Family Estate <br /> 460,500, 520, 550 Tonkana Road, Orono,Minnesota <br /> OBJECTIVES AND SCOPE OF SERVICES <br /> SPC Engineering&Testing,Inc.,4764 Europa Trail,Hugo,Minnesota,55038 was retained <br /> by Construction Consulting & Inspections, Limited, herein after referred to as the "Client", to <br /> perform a subsurface geotechnical assessment on a parcel of land located at the address in the above <br /> title block.The purpose of this investigation is to identify and evaluate soil properties on the site with <br /> respect to re-constructing the existing bituminous street and driveways,thereon. <br /> June 12, 2008, five soil borings were performed to nominal depth of 11.5±feet within the <br /> project area at locations directed by the client. From the resulting data recommendations are <br /> presented regarding pavement design. <br /> SCOPE OF SERVICES <br /> The client authorized the following scope of services: <br /> Perform five(5) standard penetration test boring to nominal depths of be 11.5±feet below <br /> grade or refusal. <br /> Sample soil using a 2"O.D.split-barrel sampler driven into the soil by a 140 lb weight falling <br /> 3 0".After an initial set of 6",the number of blows required to drive the sampler an additional <br /> 12"is known as the penetration resistance or N-value.The N-value is an index of the internal <br /> friction of cohesionless soil, the consistency of cohesive soils, and the density of all soils. <br /> Sampling will conform to the methods set forth in ASTM procedure D1586-84. <br /> Classify recovered soil samples by the Visual-Manual method in accordance with ASTM D- <br /> 2488. Representative portions of the samples may be submitted to the laboratory for further <br /> examination and for verification of the field classification in accordance with ASTM D2487- <br /> 85. Information indicating depth and identification of the various strata,the N-value,water <br /> level information and pertinent information regarding the drilling method will be documented <br /> on comprehensive soil boring logs. <br /> Prepare an engineering report including a log of each boring along with our recommendations <br /> for allowable soil bearing pressures and estimates of foundation settlement. <br /> The purpose of this report is to present the results of our field and laboratory exploration assessment <br /> and the associated engineering review.Please note that this report is for geotechnical purposes only <br /> and is not intended to document the presence or absence of any environmental contaminants that <br /> could be present at the site. <br /> 1 <br />
