ABSTRACT
Full drilled displacement piles (DDP) were selected for a project located in central new Jersey and a full-scale static load test was performed to confirm the piles could meet the design requirements. Due to higher than anticipated installation times, it was decided to change to a partial drilled displacement pile (PDDP) option prior to starting production pile installation. PDDP test piles were installed, and drill times reduced significantly. A single PDDP pile was dynamically tested to confirm the alternate pile type met the design capacity. Results of the capacity predictions will be compared to the load test results for both pile types.
