21 <br /> WSP will locate proposed borings in the field using a handheld Trimble GPS unit and the as-drilled <br /> location/coordinates will be collected using GPS equipment at the time of boring completion. <br /> One split spoon sample collected will be tested in our NCDOT approved Materials and Testing Laboratory to <br /> verify visual field classification and determine soil index properties. One selected cored rock sample is planned <br /> for Rock compression strength tests, according to ASTM D7012 Method C. <br /> Task 12.2-Recommendation Report <br /> WSP will prepare a geotechnical recommendation report with a typical NCDOT foundation design <br /> recommendation report. The report will consist of project understanding, site geologic overview, subsurface <br /> conditions, and NCDOT foundation design recommendations. <br /> The NCDOT foundation design recommendations will follow the Geotechnical Engineering Unit Guidelines and <br /> Procedures Manual and will meet AASHTO LRFD design criteria and NCDOT foundation design policies. The <br /> design work will address but not be limited to the following topics: <br /> • Select the appropriate and cost-effective foundation type <br /> • Axial Capacity <br /> • Lateral Stability analysis <br /> • Pile drivability analysis and the range of hammer energy if needed. <br /> • Slope stability at the end bents <br /> • Embankment settlement analysis, if needed, long-term consolidation, waiting periods and settlement <br /> monitoring will be included. <br /> The foundation recommendations report will be submitted in a single PDF file that will include foundation <br /> design recommendations, foundation notes on plans, special notes on plans and pay items quantity sheets. <br /> Task 12 Fee$25,663.31 <br /> Task 13- 100% Structure Plans Pre-Fabricated Pedestrian Bridge over 1-40- OPTIONAL ADDITIONAL <br /> SERVICES <br /> - Task 13.1 —90%Plan Development <br /> Based on comments received on the preliminary plans, WSP will finalize the design to 90%plans and all previous review <br /> comments will be addressed. WSP will complete the design and detailing of the bridge during this phase and coordinate <br /> with a prefabricated bridge manufacturer for loads to the substructure. <br /> Specific tasks to be completed during this phase of the project include the following: <br /> - Final Design of substructure <br /> - Plan development of substructure details,including notes, and general details for the prefabricated superstructure <br /> such as length and clear width of bridge <br /> - Quantity Calculations <br /> Page 11 <br />
