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 4 <br />engineer and will include visual classification, moisture content, dry density, Atterberg limit, and <br />strength tests (unconfined compression), as appropriate. <br /> <br />To assist in our analysis of the long-term factor of safety, we propose two consolidated- <br />undrained triaxial tests with pore pressure readings. Each test would include three points. <br /> <br />Engineering Analysis and Report – The results of our field and laboratory programs will be <br />evaluated by a professional geotechnical engineer licensed in the State of North Dakota. Based <br />on the results of our evaluation, an engineering report will be prepared that details the results of <br />the testing performed, provides logs of the borings, and a diagram of the site/boring layout. The <br />report will include the following: <br /> <br />■ Boring logs with soil stratifications based on visual soil classification. <br />■ Summarized laboratory data. <br />■ Groundwater levels observed during and after completion drilling <br />■ Boring location plan. <br />■ Subsurface exploration procedures. <br />■ Encountered soils conditions. <br />■ Construction difficulties. <br />■ Analyzing the factor of safety with respect to long-term stability for each of the three <br />options. Our analysis would include selecting one cross-section representing the worst- <br />case condition, based on the cross-sections provided. <br />■ Other slope configurations could be analyzed, as requested based on results of the first <br />three analyses. Depending upon the number of analyses requested, it is possible the <br />budgeted analysis time may exceed our estimated total cost for the project. <br /> <br />Schedule - We can generally begin the field exploration program within about one to two weeks <br />after receipt of our signed Agreement for Services, if site and weather conditions permit. <br />Completion of the triaxial shear testing will take approximately 3 to 4 weeks after the soil borings <br />are completed. We estimate the analyses and preparation of the report would take another 2 to <br />4 weeks after all laboratory testing is complete. <br /> <br />C. COMPENSATION <br /> <br />For the scope of geotechnical services outlined in this proposal that includes drilling, laboratory <br />testing, and an engineering report, we estimate the total cost will range from $18,000.00 to <br />$20,000.00. We would not exceed a total cost of $20,000.00 without additional notification to <br />proceed. Our cost estimate includes a budget of 12 hours for analysis time (approximately 4 <br />hours per option). If other cross-section/setback distances are evaluated, there would be an <br />additional charge for analysis time beyond the budgeted 12 hours. <br />
