Within an EDC, sensors such as accelerometers, strain gauges, temperature sensors and corrosion sensors, can be used to record and transmit data wirelessly to determine axial resistance and integrity during each hammer blow during pile driving. 73 Member Profile: William (Bubba) Knight: A Wide and Varied Career SPECIAL ISSUE : COVER STORY ® 14 Rapid Load Testing of Foundation Piles in Barcelona Nicolás Moscoso, Carlos Fernández Tadeo, Marcel Bielefeld, and Gerald Verbeek The authors provide a review of the methodology for rapid load testing, its application and analysis of test results. Then, the authors provide a mini case history highlighting the use of the StatRapid device to dynamically test 25 cast in-situ reinforced concrete piles as an alternative testing approach when bi-directional load testing did not produce the desired axial resistance.
