GEOTECHNICAL EXPLORATION USERS GROUPS
A Sound Concept that Deserves to Be Expanded
Whenever an organization launches an
initiative, the question arises whether
that initiative has staying power. Or is
the initiative, as is quite often the case,
merely a fad; that is, just an activity that
suddenly becomes popular, but which
does not stay popular for very long.
When the Federal Highway Administration
(FWHA) started its Advanced
Geotechnical Methods in Exploration
(A-GaME) initiative, that question was
addressed, especially considering the
fact that up to 50% of major infrastructure
projects suffer impacts to schedule
or cost due to geotechnical issues.
Many of these issues relate to risks
Learn more about the FHWA's Advanced Geotechnical
Methods in Exploration (A-GaME) initiative
identified directly or indirectly to the
scope and quality of site characterization
work. Effective site characterization
is critical for recognizing
potential problems that may affect
design and construction and for
ensuring safe, well-performing and
cost-effective projects. Grounded on
that, knowledge of all available site
investigation methods should continue
to be shared widely and the application
of those methods should be encouraged
on an ongoing basis throughout the
project lifecycle.
The A-GaME initiative covers five
technologies: Cone penetration testing
(CPT), monitoring while drilling (MWD),
electrical geophysical methods, seismic
geophysical methods, and optical and
acoustic televiewers. Of these, three soil
and rock investigation methods were
highlighted that are underutilized not
only here in the U.S., but also in many
places around the world:
* CPT: a well proven and established
method for soil characterization
that turned 90 last year, in which
continuous in-situ data are collected
quickly and consistently.
* Geophysics: the science that
assesses the physical properties of
the soils and rock using seismic and
electrical techniques, which continues
to advance in leaps and
bounds as the application of wellunderstood
technologies become
more powerful.
