Integrity test methods require careful interpretation, which should be performed by experienced 8 - DESIGN AND CONSTRUCTION OF CONTINUOUS FLIGHT AUGER PILES – FINAL - April 2007” by FHWA.

Here is what I found in “GEOTECHNICAL ENGINEERING CIRCULAR (GEC) No. RE: PIT - Pile Integrity Testing - Requirements? Armar007 (Structural) They have equipment that will provide similar information by monitoring and recording the integrity of each pile as it is installed, without causing any loss in production time. You may want to look at the GRL/PDI website, they practically invented pile integrity testing. There are newer and more reliable methods of determining the integrity of drilled piles. These tests are the oldest typically performed, and can be relatively time consuming. We have DOT projects that require every drilled pile undergo integrity testing, so again I believe the quantity/frequency should be specified by the engineer. D6760 is a good test, but is highly dependant on the installation of the access tubes and the timing of the testing. I do not favor D5882, due to variations of the surface conditions of the piles. The engineer may require additional testing during the production piles if there are any that are suspect, due to low grout takes or abnormal installation conditions. The test piles are then selected from the index pile program, usually the worst case situations and the average conditions. Typically, the piling contractor performs an index pile program, by selecting pile locations across the site to install and record data prior to production work. If they are going to tell you that this testing has to be done, then they should also be telling you how often. P8000 Wireless Pile Integrity Tester : is a Wireless Foundation Pile Dynamic tester or pile dynamic analyzer using the low strain reflected wave method for testing integrity of Concrete Pile and identify the extent and location of pile defect.I'll agree that 10% sounds reasonible, but the bottom line is it should be in the specifications.

Two Pile integrity tester`s options are available: Pile Integrity Tester may also be used to test piles primary in the structure, such as those supporting existing bridges or towers. The utilization of the Pile integrity tester is necessary for testing of building foundation piles, Dynamic Pile tests in highway engineering, and exposed top surface of constructions such as pillars and for non destructive testing of railway piles Pile Integrity Tester (PIT) perform low strain integrity testing also known as sonic echo or pulse echo testing for assessing the condition of piles. Stanlay is preferred & authorized pile testing equipmentsupplier in India.
