Proposal for Geotechnical Engineering Services Irerracon <br /> Proposed Water/Sewer Improvements a Mebane, North Carolina <br /> November 19,2012 a Terracon Proposal No. P70120505 <br /> A written log will be kept of the- SPT testing and the soil strata observed in each boring. <br /> Representative portions of the soil samples will be retained in sealed, plastic bags and <br /> transported to our laboratory for further testing, if appropriate, and for storage. <br /> Based on review of aerials, it appears that many of the boring locations will be accessible to our <br /> ATV drilling equipment without the need for clearing or difficult maneuvering. However, some <br /> locations will be require chainsaw clearing if clearing cannot be provided ahead of time by the <br /> project team. If clearing cannot be provided ahead of time we suggest a budget of$2,000 <br /> be provided to cover the costs of hand clearing to the boring locations. Due to the <br /> distance between locations, transfer of the drill rig by motor carrie will be required to access the <br /> various boring locations. <br /> Laboratory Testing — The samples will be tested in our geotechnical laboratory to determine <br /> physical engineering characteristics. Testing will be performed under the direction of a <br /> geotechnical engineer and may include visual classification, moisture content, Atterberg limits, <br /> and grain size analysis, as appropriate. <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 Carolina. <br /> Based on the results of our evaluation, an engineering report will be prepared that details the <br /> results of the testing performed, provides logs of the borings, and a diagram of the site/boring <br /> layout. The report will include the following: <br /> N Computer generated boring logs with soil stratification based on visual soil classification. <br /> N Summarized laboratory data. <br /> N Groundwater levels observed. <br /> a Boring location plan. <br /> ■ Subsurface exploration procedures. <br /> ■ Encountered soil or bedrock conditions. <br /> a Subgrade preparation/earthwork recommendations for trenching/boring operations. <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. We also request information concerning awareness and/or <br /> location of any private subsurface utilities existing in the area. We will contact NC One-Call for <br /> location of utilities in public easements along roadways. <br /> Schedule—We anticipate that the fieldwork will take 7 to 8 days to complete. We estimate the <br /> final geotechnical report can be completed within about two weeks after the field services are <br /> completed. In situations where information is needed prior to submittal of our report, we can <br /> provide verbal information or recommendations for specific project requirements after we have <br /> completed our field and laboratory programs. <br /> Responsive a Resourceful a Reliable 3 <br />
