DocuSign Envelope ID: B01E86EC-6FC1-43CE-8E90-79CF68C52249 <br /> ECS Southeast, LLP <br /> and offsite sewer lines running through a new easement that will tie in at the southeast corner of the <br /> development. <br /> PROPOSED SCOPE OF SERVICES <br /> Based on the project information provided to and obtained by us, in addition to our previous experience <br /> with this site, we propose the following scope of geotechnical engineering services for this project: <br /> Field Exploration <br /> a. Field locate borings by using hand-held GPS unit, referencing existing site features, and using <br /> available plans. <br /> b. Clear paths through wooded areas using a hydro-axe or similar mulching equipment to provide <br /> drill rig access to the relevant borings locations. <br /> C. Mobilize an All-Terrain Vehicle (ATV) mounted drilling rig to the site. <br /> d. Perform 28 borings to depths of 20 feet below existing grades within the proposed building <br /> areas, 2 borings to a depth of 15 feet below existing grades along the proposed sewer utility <br /> alignment, and 3 borings to a depth of 15 feet in proposed SCM area. The borings will be <br /> extended to the proposed depths below the existing ground surface, unless refusal to drilling <br /> advancement causes them to be terminated at a more shallow depth. Hollow stem auger drilling <br /> techniques are proposed. <br /> e. Perform Standard Penetration Test (SPT) tests at standard intervals within the borings for <br /> engineering analysis. <br /> f. Obtain 3 bulk samples of auger cuttings from select borings for laboratory testing. <br /> g. Measure depth of groundwater within each boring at time of drilling and prior to backfilling. <br /> h. Advance 2 hand auger borings within the proposed water utility alignment along US 70 West. <br /> Soil cuttings will be visually classified in general accordance with the Unified Soil Classification <br /> System. Some soil samples will be returned to ECS' laboratory for testing of index properties. <br /> i. Advance 2 hand auger borings to a depth of 10 feet or refusal to evaluate the soils for <br /> indications of the seasonal high water table (SHWT). SHWT observations will be conducted <br /> during SPT drilling in lieu of performing hand auger borings if possible. The soil cuttings will be <br /> visually classified in accordance with the US Department of Agriculture system. The <br /> characteristics of the soil will be observed, including texture and color, to determine the depth <br /> to the seasonal high water table. The assessment will be conducted in accordance with current <br /> soil science practices, current technology, and the North Carolina Division of Environmental <br /> Quality Stormwater Design Manual (April, 2017). <br /> For your convenience, the "Subsurface Investigation Exhibit" prepared by Civil Consultants indicating the <br /> requested boring and test locations is attached to this proposal. <br /> Laboratory Testing <br /> Upon completion of drilling operations, the samples will be returned to our laboratory in Raleigh, North <br /> Carolina for further identification and testing, including: <br /> a. Visual-manual classification in accordance with the Unified Soil Classification System. <br /> b. 10 natural moisture tests. <br /> ECS Proposal No:06:21174 <br /> Page 13 <br />
