Financial Project ID (s): 431759-1-4B/42/43/45-01 <br />Stage I, II or III <br />ATRUE COPY <br />CERTIFIFATTIQERON K LAST PAGE <br />• Hire a Specialty Engineer to perform non-destructive integrity testing of drilled <br />shafts as required to estimate shaft uniformity and to detect possible shaft defects. <br />Report results to the DGE. <br />• Evaluate problems encountered during construction, and coordinate with the DGE <br />and the Contractor to resolve such problems, including possible withdrawing <br />Drilled Shaft Installation Plan approval. <br />2) Piles: <br />• Process and review the Pile Installation Plan in accordance with CPAM. <br />• Perform preliminary Wave Equation Analyses to assess and provide comments <br />regarding the suitability of hammer driving system(s) included in the Pile <br />Installation Plan. Provide analyses results (estimated blow count ranges for the <br />nominal bearing resistances, installation stresses etc.) to the DGE. <br />• Schedule a pre -pile installation meeting to review and discuss the pile installation <br />procedures. Make sure the Contractor's field superintendent, CEI's pile inspectors, <br />and the DGE are invited. Prepare and distribute meeting minutes to the attendees. <br />• Provide personnel proficient in operation of the PDA or EDC monitoring <br />equipment required for the project, for data collection, interpretation and analysis. <br />Utilize the most current version of equipment and software for dynamic testing and <br />dynamic data analysis. <br />• Perform dynamic testing per the contract documents during initial driving and re - <br />drives. Submit electronic Pile Driving Analyzer (PDA) and Embedded Data <br />Collector (EDC) files upon completion of the test pile installation. <br />• Inspect and record the test pile driving process in accordance with CPAM. <br />• Perform signal matching analysis on test pile data for selected blows, using the <br />latest software version. At a minimum, signal matching analysis shall be <br />performed on initial drive data where required resistance is obtained below the <br />minimum tip elevation and on set -check data (if any). If requested in special <br />circumstances, the end of drive signal matching analysis will be performed in the <br />field upon completion of the drive; otherwise it shall be completed within 24 hours <br />of driving the instrumented pile. <br />• Analyze the test data and available soils data as required to establish production <br />pile lengths and driving criteria. The analysis must include signal matching <br />analysis and wave equation calibration analysis to determine a pile driving -soil <br />system model that will predict accurately driving resistance with stroke (or <br />pressure) and blows per foot while matching transferred energy and dynamic <br />stresses with the ones measured in the field. Submit preliminary report(s) <br />recommending production pile lengths and driving criteria to the DGE for <br />approval. The preliminary report shall include printed & plotted Signal Matching <br />and Wave Equation Analysis outputs, and electronic files (Windows compatible) <br />of all raw data obtained by the PDA and EDC equipment and the signal matching <br />and wave equation analyses. <br />• Furnish final written letters, signed and sealed, for production pile lengths and the <br />driving criteria in accordance with CPAM. When applicable, include <br />recommendations to determine "firm bearing material". <br />• Inspect the conditions of the piles prior to installation, including any pile splices. <br />• Observe and verify that concrete piles were properly supported during storage and <br />handled with appropriate pick-up details per contract documents. <br />• Inspect the pile driving installation. Complete the FDOT pile driving logs. <br />A- 15 Version 1.0 <br />
