DocuSign Envelope ID: AFOFC7DF- FDAD- 4E58- A786- 72F744EA8560 <br />June 22, 2018 ECS Southeast, LLP <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. 2 natural moisture tests. <br />C. 2 gradation analysis tests (wash sieve). <br />d. 2 Atterberg Limit tests. <br />Report <br />Upon completion of testing and engineering analysis, we will prepare a geotechnical engineering report <br />addendum that presents our findings and recommendations. The addendum will include the following <br />items: <br />a. A subsurface characterization and a description of the field exploration and laboratory tests <br />performed. <br />b. Logs of the soil borings prepared in accordance with the standard practice for geotechnical <br />engineering. A boring location plan will be included, and the results of the laboratory tests will <br />be plotted on the final boring logs or included on a separate test report sheet. Elevations will be <br />interpolated from civil drawings and /or referenced from published topographical maps. <br />C. Recommended allowable soil bearing pressure(s) for conventional shallow foundations (spread <br />footings) and estimates of predicted foundation settlement. We will provide recommendations <br />for suitable intermediate foundations /ground improvement options in the event estimated <br />settlements of shallow foundations are not tolerable. <br />d. Recommendations for slab -on -grade design and construction, including recommendations for <br />subgrade improvements and the capillary break layer. <br />e. Evaluation of the on -site soil characteristics encountered in the soil borings. Specifically, we will <br />discuss the excavatability of the on -site materials and the suitability of the on -site materials for <br />reuse as engineered fill. We will also include compaction requirements and suitable material <br />guidelines. <br />f. Recommendations for additional testing and /or consultation that might be required to complete <br />the geotechnical assessment and related engineering for this project. <br />ECS Proposal No: 06:20895 <br />Page 16 <br />9i V <br />
