DocuSign Envelope ID: AFOFC7DF- FDAD- 4E58- A786- 72F744EA8560 <br />June 22, 2018 ECS Southeast, LLP <br />of the existing driveway. The proposed expansion to the Seymour Center parking lot will cut into the <br />hillside and a new retaining wall may be required in this area. <br />Design foundation loads have not been provided to us, but we assume they will be relatively light <br />(column loads up to 75 kips and wall loads up to 3 kips per foot). <br />Design grades have not been provided to us. Based on existing site grades, the site plan provided to us, <br />and our experience with similar projects, we assume that cut and fill depths will be less than 10 feet for <br />general site grading. <br />PROPOSED SCOPE OF SERVICES <br />Based on the project information provided to and obtained by us, in addition to our experience with <br />numerous similar types of projects and nearby sites, we propose the following scope of geotechnical <br />engineering services for this project: <br />Phase 1— Initial Geotechnical Exploration <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 hand operated equipment to provide drill rig access to <br />the borings locations. <br />C. Mobilize an All- Terrain Vehicle (ATV) mounted drilling rig to the site. <br />d. Perform up to 10 borings to a maximum depth of 20 feet at the approximate locations indicated <br />on Figure #2 on page 3 of the RFP. The borings will be extended to the proposed depths below <br />the existing ground surface, unless auger refusal causes them to be terminated at a more <br />shallow depth. Hollow stem auger drilling techniques are proposed. <br />e. Perform Standard Penetration Test (SPT) tests at standard intervals within the borings for <br />engineering analysis. <br />f. Measure depth of groundwater within each boring at time of drilling and prior to backfilling. <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. 5 natural moisture tests. <br />ECS Proposal No: 06:20895 <br />Page 12 <br />.e- <br />
