9. Additionally, a total of four (4) samples of existing topsoil will be collected <br />within the project corridor for topsoil testing in accordance with Sections 3.6.6 <br />and 5.21 of the IGM. <br />10. Rii field crews will exercise caution to minimize ground damage and will make <br />reasonable efforts to restore the ground to the original condition. Any ground <br />and vegetation damage incurred while gaining access to boring locations will <br />be documented and reported. <br />11. Should subsurface conditions be encountered during test drilling that indicate <br />additional or special drilling and/or special testing or analysis are required, we <br />will contact your office for approval prior to proceeding. <br />12. During drilling, Rii will provide traffic control during the execution of the drilling <br />program in accordance with the INDOT Worksite Traffic Control Manual. <br />Lane closures will be required during execution of the field work. Therefore, <br />traffic control will be provided using a combination of signs, cones, flaggers <br />and arrow boards, as required. This proposal considers that there will be no <br />time restrictions associated with the required permitting and that traffic <br />control and drilling operations can be performed within full 8-hour work days. <br />C. Testing Program <br />In the laboratory, all samples will be visually classified and tested according to the <br />IGM. Laboratory testing of representative samples will be performed in accordance <br />with ASTM/AASHTO procedures to classify existing soils according to the AASHTO <br />Classification System and to estimate engineering properties of importance for <br />pavement and foundation design and construction considerations. In addition, the <br />pavement cores will be visually described and photographed. The expected tests to <br />be performed and the estimated quantities are presented in the attached fee <br />schedule. <br />The soil samples and pavement cores will be retained for a period of sixty (60) days <br />after the completion of the geotechnical report, unless otherwise directed. <br />D. Geotechnical Data Report <br />Engineering evaluation and analysis shall be performed, and a report prepared and <br />delivered (electronic PDF files) to include the following: <br />Geology of the site including geological surface features, a description of <br />topography, drainage conditions and surface vegetation. <br />American Structurepoint, Inc.
