DiscussionTest Pile ProgramPDA /EDC test pile programs shall be implemented prior to the approval of concrete pile order lengths for larger projects and as subsurface conditions warrant. Static load tests shall be undertaken on very large projects to decrease the required geotechnical factor of safety and reduce pile order lengths. Pile DrivingUsing EDC during driving shall be monitored by a geotechnical specialist certified to collect and analyze EDC data. EDC is warranted for driving marine concrete piles in order to prevent pile cracking and damage. Third-party underwater inspections of all concrete driven piles shall be conducted as soon as possible after driving to identify and scope the repair of driving damage. To the greatest extent possible, allowable tensile driving stresses for concrete piles shall be reduced for in-water piles where damage is detected by EDC gauges, PDA instrumentation (beta<0.90 for more than 10 consecutive blows) and/or underwater inspection.
