Pile Dynamics Inc. (PDI) was established in 1972 by Dr. Frank Rausche with Garland Likins.
The company developed from work done at Case Western Reserve University (Case), originally Case Institute of Technology. It began as a research project entitled Dynamic Studies on the Bearing Capacity of Piles.[1] As part of this project several graduate students and faculty conducted research that included Dr. Frank Rausche when he was a student. He was advised by Professors George Goble and Fred Moses. The project entailed using one-dimensional stress wave theory to derive the Case Formula which lead to the invention of the Pile Driving Analyzer (PDA).[2] This device calculates the pile bearing capacity in real time from impact tests on foundation piles.
Likins, another former Case graduate student, further transformed the University prototypes into a routinely usable device and user-friendly software. PDA implemented many new details of dynamic soil modeling and transducer technology and described these efforts in many publications and presentations.
CAPWAP[3] is a dynamic testing tool with an extensive published correlation study comparing its results favorably with static load tests; as a result CAPWAP is the industry standard in signal matching software. Based on this thorough research and development effort PDI's dynamic pile testing methods found acceptance around the world.
PDI has added other products as it develops additional quality assurance/quality control testing equipment and technologies for the deep foundations industry.
