The following geotechnical engineering services shall be performed: 1) Piles: Process and review the Pile Installation Plan in accordance with CPAM. Perform preliminary Wave Equation Analyses to assess and provide comments regarding the suitability of hammer driving system(s) included in the Pile Installation Plan. Provide analyses results (estimated blow count ranges for the nominal bearing resistances, installation stresses etc.) to the DGE Schedule and coordinate a pre-pile installation meeting to review and discuss the pile installation procedures. Make sure the Contractor’s field superintendent, CEI’s pile inspectors, and the DGE are invited. Prepare and distribute meeting minutes to the attendees. Provide personnel proficient in operation of the PDA or EDC monitoring equipment required for the project, for data collection, interpretation and analysis. Utilize the most current version of equipment and software for dynamic testing and dynamic data analysis. Perform dynamic testing per the Contract Documents during initial driving and redrives. Submit electronic Pile Driving Analyzer (PDA) and Embedded Data Collector (EDC) files upon completion of the test pile installation. Inspect and record the test pile driving process in accordance with CPAM. Perform signal matching analysis on test pile data for selected blows, using the latest software version. At a minimum, signal matching analysis shall be performed on initial drive data where required resistance is obtained below the minimum tip elevation and on set-check data (if any). If requested in special circumstances, the end of drive signal matching analysis will be performed in the field upon completion of the drive; otherwise, it shall be completed within 24 hours of driving the instrumented pile.
