The Vibro-Pile® being tested with a 500 ton jack.  Seven test  piles were installed for the initial testing program to prove the ground, the installation technique and to optimize the design.  A total of 613 production piles were designed to support the 3 foot thick parking slab,  25 feet below grade level.  With a high water table, most of the piles are in tension, to keep the 2 levels below grade structure from popping up like a cork.  Initially, driven piles were designed.  However, after a value engineered proposal from August, the design was modified to the Vibro-Pile®, a proprietary (patent pending) driven displacement CAST-IN-PLACE pile.  The Vibro-Pile® has far superior bonding to the soil vs. a driven pile, since it's cast in place and pressure grouted using the Vibro-Probe®.
