� ' STOI�I� Stork Twin City Testing Corporation <br /> Materials Technology <br /> Proposed Addition at Residence 965 Edgewood Hilis Road Page 4 of 9 <br /> Orono, Minnesota <br /> Stork Twin City Testing Corporation Project #3106831 <br /> The borings terminated in lean clay glacial till that was firm based on the penetration <br /> values (N-value) obtained during drilling. <br /> 2.4 Water Level Conditions <br /> Water level observations were made during and after completion of the drilling <br /> operations. Groundwater was not encountered at the time of drilling in the borings. <br /> Since the clay soils encountered in the test borings are relatively impervious or slow <br /> draining, it may take several days for groundwater in a borehole to rise to its hydrostatic <br /> level. If more accurate water level determinations are required, piezometers should be <br /> installed and the water level monitored over a period of time. <br /> In general, water levels may fluctuate throughout the year depending on variations in <br /> the amount of precipitation, degree of evaporation, surface run-off characteristics and <br /> other related hydrogeological factors. <br /> 3.0 LABORATORY REVIEW <br /> The soil samples obtained during the drilling operations were logged, labeled, sealed <br /> and delivered to our laboratory for further review. The soil samples were classified in <br /> general conformance with ASTM Standards by a Twin City Testing geotechnical <br /> engineer. <br /> 4.0 ENGINEERING REVIEW <br /> Based on the information obtained from our geotechnical work and our understanding or <br /> assumptions of the project data, we made our engineering review and <br /> recommendations which are presented in the following sections. If any of our <br /> understanding or assumptions are not correct, or if conditions observed during <br /> construction are significantly different than those encountered in our geotechnical work, <br /> we should be contacted immediately so we may review our recommendations. <br /> This agreement shall be governed exclusively by the general terms and conditions of sale and performance of testing services by Stork Twin City <br /> Testing,Inc.a North Carolina business corporation("TCT")dd.02/04/2001. In no event shall Stork Twin City Testing,Inc.be liable for any <br /> consequential,special or indirect loss or any damages above the cost of the work. Payment is due within 30 days of invoice. <br />
