Tegre Corporation Job No. 3124JS057 3.0 SCOPE OF SERVICES 3.1 Field Exploration Fourteen borings were drilled for this project to nominal depths of 21/2 to 35 feet. The borings were advanced until encountering auger refusal in the cobble and boulder layer. The borings were drilled using a CME-75 drill rig advancing 7-inch-diameter hollow-stem augers. The borings were drilled at the approximate locations indicated on the attached Boring Location Diagram (Figure 3). The GPS coordinates at each boring location are indicated at the bottom of the boring logs. The approximate ground surface elevation at each boring location is indicated at the top of the boring logs. A WT geotechnical engineer monitored the drilling operations and prepared a field log for each boring. These logs contain visual classifications of the materials encountered during drilling as well as interpolation of the subsurface conditions between samples. The final boring logs, included in Appendix A, represent our interpretation of the field logs and may include modifications based on laboratory observations of the recovered soil samples. The final logs describe the materials encountered, their thicknesses, and the depths at which samples were obtained. The Unified Soil Classification System was used to classify the soil. The soil classification symbols appear on the boring logs and are briefly described in Appendix A. 3.2 Laboratory Testing Laboratory tests were performed on representative samples to aid in material classification and to estimate the pertinent engineering properties of the encountered material.Testing was performed in general accordance with applicable ASTM methods. The following tests were performed and the results are presented in Appendix B. • Water Content • Liquid and Plastic Limit • Dry Density • Grain Size Analysis • Pocket Penetrometer • Unconfined Compression 2
