Effective measures, such as warning signs and restricted access, must be implemented to keep personnel away from the test area while loading is in progress.
Piles must never have their alignment adjusted by force during the jacking process. Effective measures, such as warning signs and restricted
Designers are encouraged to conduct adequate site investigations, including probe holes at every pile group location to detect potential voids or cavities. A pile is generally considered "set" if the
Current standards emphasize performance-based design where designers review instrumented Ultimate Load Test (ULT) results to verify design parameters. tests like Sonic Logging
Jacking continues until practical refusal is reached. The load is then released and reapplied to measure the "set".
A pile is generally considered "set" if the downward movement does not exceed 10 mm (some guidelines specify 5 mm ) during a holding time of at least 30 seconds .
After installation, tests like Sonic Logging , PDA/PIT , or Full Coring are used to assess the structural integrity of the piles. 5. Performance-Based Design
