Proposal for Geotechnical Engineering Services <br />Norman Lutheran Church Riverbank Repair ■ Kindred, North Dakota <br />May 17, 2012 ■ Terracon Proposal No. PM1120117 <br /> <br />Reliable ■ Resourceful ■ Responsive 3 <br />indicates the soil conditions would likely consist of silt and soft fat clays extending to a depth on <br />the order of 85 feet. Therefore, the assumed sheet pile length of 78 feet would not likely <br />penetrate the very stiff to hard sandy lean clay expected below the soft gray fat clays. We <br />propose a boring depth of 100 feet for all three borings. The purpose would be to determine the <br />depth of soft lacustrine clays at the site. <br /> <br />Sampling will be in general accordance with industry standard procedures wherein Shelby tube <br />samples or split-barrel samples are obtained. One (1) split-spoon sample will be taken at 2½ foot <br />intervals to a depth of 15 feet, followed by a sampling interval not more than five feet in the <br />remainder of the deep borings. Soil sampling will be performed in accordance with ASTM D1586 <br />and D1587. In addition we will observe and record ground water levels during and after drilling. <br />Once the samples have been collected and classified in the field, they will be placed in <br />appropriate sample containers for transport to our laboratory. <br /> <br />Conditions/Items to be provided by Client: Items to be provided by the client include the right of <br />entry to conduct the exploration and an awareness and/or location of any private subsurface <br />utilities existing in the area. We will contact North Dakota One Call for location of utilities in <br />public easements. Location of private lines on the property is not part of the North Dakota One <br />Call or Midwest Testing/Terracon scope of work. All private lines should be marked by others <br />prior to commencement of drilling. <br /> <br />Midwest Testing/Terracon will take reasonable efforts to reduce damage to the property, such <br />as rutting of the ground surface. However, it should also be understood that in the normal <br />course of our work some such disturbance could occur. We have not budgeted to restore the <br />site beyond backfilling our boreholes. If there are any restrictions or special requirements <br />regarding this site or exploration, these should be known prior to commencing field work. <br /> <br />Our fee is based upon the site being accessible to our truck-mounted drilling equipment and <br />Midwest Testing/Terracon providing layout of the borings; additional costs may result if this is <br />not the case. It does not include services associated with site clearing, wet ground conditions, <br />tree or shrub clearing, damage of existing crops / landscape or location of underground utilities <br />beyond contacting a “one-call” locate service. If such conditions are known to exist on the site, <br />Midwest Testing/Terracon should be notified so that we may adjust our scope of services and <br />fee, if necessary. <br /> <br />For safety purposes, all borings will be backfilled immediately after their completion. Excess <br />auger cuttings would be disposed of on the site. Because backfill material often settles below <br />the surface after a period of time, we recommend the boreholes be checked periodically and <br />backfilled if necessary. We could provide this service at your request or grout the holes, but this <br />would involve additional cost. <br /> <br />Laboratory Testing – The samples will be tested in our laboratory to determine physical <br />engineering characteristics. Testing will be performed under the direction of a geotechnical
