0!4 <br />APPENDIX 2 <br />TO THE <br />ENGINEERING SERVICES CONTRACT <br />BETWEEN <br />LEE COUNTY, NORTH CAROLINA <br />AND <br />L.E. WOOTEN AND COMPANY DBA THE WOOTEN COMPANY <br />FOR <br />CIVIL ENGINEEERING DESIGN AND CONSTRUCTION ADMINISTRATION <br />TO <br />CLYDE RHYNE DRIVE EXTENSION — ROAD UYIPROVEMENTS <br />The following Attachment shall become a part of the Contract Agreement. <br />I.A. DESIGN SERVICES <br />(1) Topographic and Design Survey, including ground shots on a 50 -ft grid interval and roadway <br />cross - sections on a 50 ft interval to develop 1 -ft topographic contour elevations and design <br />base files as required to design the Project. Survey area is approximately 100 -ft wide corridor <br />for the length of the roadway, approximately 8,000 linear feet. <br />(2) Provide preliminary research of existing easements and right -of -way in the project area. <br />Advise owner of easements and right -of -way needed. <br />(3) Identify wetlands, streams and Riparian Buffers that may be subject to impacts from the <br />proposed design. <br />(4) Geotechnical Subsurface Investigation, including evaluation of existing asphalt, ABC stone, <br />and subgrade soils on the paved sections and exposed ABC stone and subgrade soils on the <br />unpaved sections. Evaluation includes core samples and measurement of pavement and ABC <br />stone thicknesses at five (5) locations along the paved portion of the road, and in -place dual - <br />mass dynamic cone penetrometer (DCP) testing and hand auger samples will be collected on <br />the subgrade soils. In -place DCP testing and hand auger sampling will be performed at sixteen <br />(16) locations along the unpaved sections of Clyde Rhyne Drive (I l on an approximate 500 -ft <br />spacing and 5 additional locations where necessary). The evaluation will provide a report of <br />findings including calculated California Bearing Ratio (CBR) values through correlations used <br />Page t of Pages <br />APPENDIX 2 <br />
