GOBLE PILE CHECK
Goble 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 (archived url: http://goblepiletest.com/)
The test is performed in accordance with ASTM D4945 - Standard Test Method for High-Strain Dynamic Testing of Deep Foundations.
Goble Pile Check (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.
H2R Corp was working alongside Dr. Goble between 2012 and 2017 when he passed away. Since 2017, H2R became the sole source and sole developer of the GPC system. GPC system is now supported by the three most powerful software programs in the world, far superior to any existing programs provided by the competitors.
The three programs are:
• GPC for data acquisition.
• GPC Report for result reporting, which includes instant automatic signal matching (iN_GAPA) results in real-time.
• N_GAPA (Nguyen Goble Automatic Pile Analysis) for signal matching analysis
Some of the features of the GPC system include:
- Users can use their own laptops – most computers easily satisfy the minimum system requirements. However, H2R is deploying GPC on tablets provided to users, so that users do not have to worry about installation and configuration.
- Data transmission is lossless – the signal is digitized in the transmitter box. In the event of a computer failure, data will not be lost. No signal degradation due to cable length and quality. System is wireless by design using IEEE 802.11, which is more reliable than Bluetooth (used by Embeded Data Collected) or 2.4 GHz wireless radio (Pile Driving Analyzer).
- Optional hardwire cable – the transmitted box may be connected by a low cost commercial off-the-shelf ethernet cable (very low cost compared to traditional DLT cable) up to 100 meters long.
- Only 1 transmitter box for both sides of the pile.
- Combination transducer – the strain gauge and accelerometer are combined on one bolt-on sensor minimizing pile drilling time and reducing complexity.
- GUI has been purpose-built to be very intuitive and easy to use.
