DocuSign Envelope ID: AFOFC7DF- FDAD- 4E58- A786- 72F744EA8560 June 22, 2018 ECS Southeast, LLP Since clearing of site vegetation is required to access some of the proposed boring locations, please note that minimum 10 -foot wide cleared paths will result. We will attempt to minimize disturbance, but felled trees and cleared underbrush should be anticipated in cleared paths. Our Cost Estimate does not include any restoration of cleared areas, moving /chipping of felled trees, etc. If there are any areas where clearing is not to be performed (such as in Resource Protection Areas (RPA) or other areas), those areas must be clearly marked on plans provided to us and should be delineated in the field with flagging prior to our mobilization to the site. ECS cannot be responsible for disturbance of sensitive or restricted areas not identified in this manner. SCHEDULE In preparing this proposal, we have assumed that the client will assist in the coordination of our access to the site with the current site owners /occupants. We anticipate being able to mobilize to the site within approximately 7 days after authorization to proceed and notification that the appropriate on -site personnel have been informed. We anticipate that the drilling operations will require about 2 days, and that the laboratory testing, after drilling is completed, will require about 3 days. Therefore, for time budget purposes, the entire scope should take about 4 weeks from initial authorization through final report submission. Verbal comments on findings can be provided within three days of completion of the borings, if requested. Phase 2 — Supplemental Geotechnical Exploration The supplemental geotechnical exploration for the proposed development will be performed, if required, once the final site layout has been established. The following scope may need to be revised based on the soil conditions encountered during the initial exploration. Field Exploration a. Field locate borings by using hand -held GPS unit, referencing existing site features, and using available plans. b. Clear paths through wooded areas using hand operated equipment to provide drill rig access to the borings locations. C. Mobilize an All- Terrain Vehicle (ATV) mounted drilling rig to the site. d. Perform up to 5 borings to a maximum depth of 20 feet at locations that will be determined at a later date. The borings will be extended to the proposed depths below the existing ground surface, unless auger refusal causes them to be terminated at a more shallow depth. Hollow stem auger drilling techniques are proposed. e. Perform Standard Penetration Test (SPT) tests at standard intervals within the borings for engineering analysis.
