Global Pile Check provide Dynamic Testing Equipment. Global Pile Check—a wireless dynamic pile tester (equivalent to Pile Driving Analyzer® – PDA – by PDI), started by Goble PileTest, Inc. of Longmont, Colorado in 2009. The test is performed in accordance with ASTM D4945 - Standard Test Method for High-Strain Dynamic Testing of Deep Foundations. GPC was pioneered by the late professor George G. Goble, Ph.D., in the late 2000’s to compete against his own former companies that he founded. Dr. Goble is the father of Dynamic Load Testing. His groundbreaking research, funded by the Federal Highway Administration (FHWA) and the Ohio Department of Transportation (ODOT) in 1968, resulted in the birth of the Pile Driving Analyzer.
