Attachment A <br />Financial Project ID (s): 436379-2-54-01 <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 />• Observe the performance of any static or statnamic load tests and review the details <br />are implemented as planned. <br />• Evaluate problems encountered during construction and coordinate with the DGE <br />and the Contractor to resolve such problems, including possible additional testing <br />and withdrawing the Pile Installation Plan. <br />3) Spread Footings: <br />Observe construction of spread footing foundations and verify that they are <br />founded at the required elevation and on the proper soil/rock material. <br />Verify the Construction Plan requirements and the applicable specifications are <br />followed throughout the spread footing construction. <br />Evaluate problems encountered during construction and coordinate with the DGE <br />and the Contractor to resolve such problems. <br />4) Auger Cast Piles for Sound Barrier Walls (N/A): <br />• Process and review the Auger Cast Pile Installation Plan in accordance with <br />CPAM. <br />• Schedule a pre -pile installation meeting to go over the auger cast pile installation <br />procedures. Make sure the Contractor's field superintendent, CEI's auger cast pile <br />inspectors and the DGE are invited. Prepare and distribute minutes to the attendees. <br />• Observe installation of demonstration pile and production piles. Submit the <br />demonstration pile reeds to the DGE. Work with the DGE to ensure that the letter <br />Stage I, II or III A- 15 Version 1.0 <br />
