Pile Dynamics supports recommendations of
revised ASTM standard for integrity testing
The American Society for Testing and Materials (ASTM) has
revised the Standard Test Method for Low Strain Impact
Integrity Testing of Deep Foundations, D5882. This Standard
covers both the Pulse Echo and Transient Response Methods
of evaluating integrity. Both methods are expedient procedures
to investigate the potential existence of major cracks
or voids in concrete foundations.
The D5882 Standard now encourages considering the
soil profile, construction method, site records and results of
tests on other foundations at the same site when evaluating
data obtained by these methods. Depending on the type of
deep foundation tested, it also suggests examining data from
concrete placement automated monitoring, concrete cylinder
or core strength tests, cross-hole sonic logging (ASTM
Standard D6760) and thermal integrity profiling (ASTM
Standard D7949).
Pile Dynamics, Inc. (PDI) wholeheartedly supports the
recommendations set forth in the revised standard. PDI
manufactures and distributes the Pile Integrity Tester (PIT),
often the instrument of choice for either pulse echo or transient
response integrity testing. PIT is available in several
INDUSTRY NEWS
models, with one or two channels of data acquisition. The
transient response method requires the models with two
channels. The technical specifications of all current PIT
models comply with the requirements of the Apparatus section
of the revised Standard.
PDI offers an extensive line of products for quality
assurance for deep foundations, including systems for the
complementary methods mentioned in D5882: automated
monitoring of concrete placement in augered piles (Pile
Installation Recorder), cross-hole sonic logging (CHAMP)
and thermal integrity profiling (Thermal Integrity Profiler).
The ASTM has more than 12,000 published standards that
are used throughout the world and may be obtained from
www.astm.org/Standard/index.html.
