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
8-6
the set-up and performance of the Static Pile Load Testing and/or the Dynamic Pile
Monitoring. It should be noted that cutoff of the piles to grade, furnishing additional
reinforcing steel and load test anchorages are usually paid for by the contract item for
piling.
The Contractor should be notified as early as possible of the equipment and personnel that
they will need to provide during a Static Pile Load Test or Dynamic Pile Monitoring opera-
tion. The assistance they provide is normally covered by the contract change order that is to
be written for the operation.
In general, for a Static Pile Load Test, the Contractor will need to provide a crane and
operator for the lifting and placement of the testing equipment off of the State transport
trailers, and for returning the equipment to the trailer once the testing is complete. The
crane will need to be capable of lifting and placing a 17,000 pound beam atop the pile test
groups. Occasionally, a 54,000 pound beam is used for load testing. The actual beam size to
be used should be confirmed with the Foundation Testing and Instrumentation Section. All
necessary rigging will be supplied by the Foundation Testing and Instrumentation Section.
The Contractor will need to provide a welder, welding machine and cutting torches to assist
in the installation of the testing equipment. Specific logistical needs and project-specific
issues should be discussed with personnel from the Foundation Testing and Instrumenta-
tion Section to ensure that efficient coordination of the test set-up is accomplished.
The Structure Representative needs to ensure that the area of the Static Load Testing and/or
Dynamic Pile Monitoring is dry and free of debris. A safe working area should be established
around the test piles, and any of the Contractor’s operations that con.ict with the work of
the testing work crews should be suspended until the testing is complete.
Section 49-1.10 of the Standard Specifications states that no piles may be drilled, cast, cut
to length or driven for a structure until the required Static Load Testing is completed.
The Standard Specifications also state that Static Pile Load Testing on concrete piles may
begin when the concrete reaches a compressive strength of 2,000 Pounds per Square Inch
(PSI), except for precast concrete piles, which cannot be driven until 14 days after casting.
Additional cement or Type III (high early) cement may be used at the Contractor’s expense.
The Standard Specifications also state that the Engineer will not require more than 5
working days to perform each test unless otherwise provided in the Special Provisions.
