Assessing Axial Capacities of Auger Cast Piles from Measuring While Drilling

The objectives of this project are (1) using ISO measuring while drilling (MWD) monitoring (crowd, penetration rate, torque, etc) on Auger Cast Pile installations for load tested piles, establish side shear vs. MWD specific energy correlation on a number of sites; (2) validate MWD correlations and developed quality assurance/quality control (QA/QC) procedures on production piles at each of the sites; (3) based on pile load tests and recovered field cores/laboratory strength testing, reassess load and resistance factor design (LRFD) phi factors for Auger Cast Piles in south Florida; and (4) use the MWD specific energy vs. pile side shear correlations from load tests to establish LRFD phi factors for future south Florida axial pile capacity QA/QC.
