Real-time Dynamic
Load Testing
Dynamic load testing (DLT) is a
quick, efficient method to provide
verification of pile capacity and
integrity by applying impact force
on the pile top while monitoring the
pile response using a Pile Driving
Analyzer (PDA). Combined with
static tests, the DLT addresses
site variability and allows a more
economical design. The PDA
monitors pile stresses to help avoid
installation damage and provides
real-time feedback on capacity.

But there’s no doubt that Section
232 action stopped the bleeding for the
domestic steel industry, and in many
cases led to positive developments.
Nearly 10,000 new jobs have been
announced since the launch of the investigation,
as steelmakers have announced
$17 billion worth of investments in plants
across the country. Steel communities like
Granite City, Ill., and Fairfield, Ala., have
reason for hope after years of suffering
under the weight of the steel overcapacity
crisis.
There’s still a problem, though. China’s
overcapacity problem never really went
away, and now the global industry once
again finds itself facing a crisis.
The good news is that Section 232 put
American steelmakers and workers on a
much stronger footing, but there’s more
that Trump and Congress can do to support
this critical U.S. industry.
For starters, they can finally make good
on long-standing promises to enact a major
infrastructure investment package, and
make sure Buy America preferences are
