About PDI

Excellence: Pile Dynamics, Inc, is a 30+ employee company led by Garland Likins and headquartered in Cleveland, OH, USA. A superb team of electronic engineers, software developers and technicians make the constant development of the PDI line of products possible. PDI excels in product quality and customer support. Since 1979, it has also offered hundreds of educational programs on deep foundation testing. Pile Dynamics is the largest manufacturer of foundation dynamic testing equipment in the world. It has a wide network of representatives spread from the Far East to Europe to South America that helps disseminate the use of its products in more than 60 countries throughout the world.

 

Early Days: In 1964, Professor George Goble (later assisted by graduate students Frank Rausche and Garland Likins) started a project at the Case Institute of Technology to research a viable alternative to conventional Static Load Tests. The efforts led to the concept of using one dimensional wave propagation theory to develop a new way of testing foundation piles - Dynamic Pile Testing. The research bore practical fruits that could be transferred to the geotechnical community. In 1972, Dr. Goble formed a company named Pile Dynamics, Inc. to commercialize the Pile Driving Analyzer® (PDA) and its associated software now known as CAPWAP®. Rausche and Likins joined the company in 1974, and since 1977 have managed its day-to-day operations.

Growth: Pile Dynamics has steadily increased its foundation testing product line. In the late 1970's PDI offered, in addition to the PDA and CAPWAP, a hand held instrument to detect and count blows during pile driving (the Saximeter). PDI later added the Hammer Performance Analyzer, the Angle Analyzer and the Pile Integrity Tester in the late 1980's. By the 1990's PDI was moving fast to incorporate new developments in electronics and personal computers to its measuring instruments. The PDA model PAK was introduced in 1991, as was the PIT Collector, the predecessor of the Pile Integrity Tester of today. By that time, geotechnical engineers had widely embraced the wave equation analysis software GRLWEAP, another PDI product that grew out of a mid-1970’s research project for the Federal Highway Administration. The SPT Analyzer joined the PDI line of products in 1995, and the Pile Installation Recorder (for Auger cast-in-place / CFA Piles) in 1998. By the year 2000, cellular phone technology had made it possible for Pile Dynamics to develop a PDA with remote testing capabilities, the PAL-R. Remote testing with data transmission via cell phone was later replaced by transmission via broad band Internet with the 2007 advent of the PDA model PAX. The evolution from the Pile Driving Analyzer first introduced in the 1970s to the 21st century PAX reflects how PDI strives to embrace and incorporate state of the art technologies into its products. Pile Dynamics' other recent product launches are the Cross Hole Analyzer, that performs crosshole sonic logging on drilled shafts, and the Acoustic Concrete Tester.
