Our
techniques apply when adding new structures:
especially
rock anchor,
microfine cement,
soil nailing,
micropile
installations for
foundation support.
We
specialize in
slope stabilization,
anchors,
permeation grouting,
foundation repair
and support,
grouting,
soil nails,
rock drilling,
micropile installations, and
sinkholes. We
use a
problem-solving approach geotechnical
architecture of buildings, bridges,
water plants, sewage plants, tunnels,
sinkholes,
caisson,
shoring,
underpinning,
agriculture, and
roads
construction. We
are experienced in these applications:
micro piles,
sinkhole repair,
permeation grouting, pressure
grout,
soil nails,
chemical grouting,
micropiles,
compaction grout, and
rock anchors.
Our specialties are
rock anchor,
acrylamide and
compaction grouting,
mini piles,
sinkhole repair,
micropiles,
acrylamide grouting, and
soil nailing.
We will continue to dedicate ourselves to
excellence,
including
insurance mortgage, in our performance, in our
integrity, and in our relationships with our
customers. We will carefully weigh our
decisions, actions, and results to make sure
that we remain the most trusted name in the
geotechnical contracting industry. Please

Static Pile Load Testing and Dynamic Pile Monitoring

Inspection Requirements During Static Load Testing and
Dynamic Pile Monitoring
It is very important that the Structure Representative ensure that all piles to be used for
Static Pile Load Testing and Dynamic Pile Monitoring be driven or constructed in accor-
dance with the contract plans and specifications. If the contract plans do not adequately
describe the test pile set-up, the Structure Representative should discuss the set-up with the
Foundation Testing and Instrumentation Section.
Test piles must be installed plumb and to the specified tip elevation shown on the plans. All
piles (anchor and test piles) within each test group should be logged for the full length of
driving. For drilled piles, a soil classification record should be kept for the full length of all
piles. If any of the driven piles have an extremely low bearing value at the specified tip
elevation (less than 50% required), the Structure Representative should contact the Foun-
dation Testing and Instrumentation Section to see if a revision of the specified tip elevation
is warranted. Changes to the specified tip elevation on test and/or anchor piles will necessi-
tate the issuance of a contract change order.
For CIDH piles, additional reinforcement is required in the anchor and test piles. This
additional reinforcement should be shown on the plans. If it is not shown on the plans or if
the details are unclear, contact the Project Designer and/or the Foundation Testing and
Instrumentation Section. The top of CIDH test piles must be level and troweled smooth.
The contract plans or Special Provisions usually require that the anchor piles be con-
structed 5 to 10 feet longer than the test piles to prevent pulling. If this is not shown, the
Structure Representative should discuss this issue with the Foundation Testing and Instru-
mentation Section to determine whether or not the lengths of the anchor piles should be
revised. Here again, any changes to the lengths of the piles may warrant a contract change
order.
If a construction project includes Dynamic Pile Monitoring, the Special Provisions for the
project will state when the piles to be used for the monitoring are to be made available for
State personnel to make the necessary preparations before these piles are driven. A techni-
cian from the Foundation Testing and Instrumentation Section will need access to the piles
to prepare them for the attachment of the necessary instrumentation. The Structure
Representative may need to ensure that the Contractor provide assistance to the technician
to maneuver the piles.
