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

Pile Foundations –
General
Specifications
The specifications for piling and pile driving are contained in Section 49 of the Standard
Specifications. Unusual requirements or options for particular projects are contained in the
Special Provisions. The project plans and Standard Plans are additional contract docu-
ments needed for pile work. As-Built plans should be obtained for widening and seismic
retrofit projects.
The normal format would be to describe the intended pile type, specified tip elevation, and,
in the case of driven piles, the minimum bearing value in the project plans or Special
Provisions or both. These documents would also include specific requirements for embank-
ment predrilling, load testing and other items peculiar to the project. For example, if
driving difficulty is anticipated, the Project Designer may allow substitution of steel “H”
piling for precast concrete piles. When this option is written into the contract, other condi-
tional clauses are usually provided (no additional compensation for piling driven below
specified tip, etc.). If the specification allowing the option is not included in the contract,
changes from one pile type to another cannot be made without the benefit of a change
order.
Structure details for the piles are found in the Standard Plans. The Standard Plans also
provide alternative details for certain pile types. This is not to be confused with the option to
substitute or change pile type as mentioned in the previous paragraph. If, for example,
Class 70C concrete piles are specified, they can be either of the alternatives shown in the
Standard Plans for Class 70C concrete piles. However, the alternatives that may be used do
not include the alternatives shown in the Standard Plans for Class 70 concrete piles.
Occasionally, the Project Designer may decide not to allow all of the alternatives for a given
pile type. In this situation, the alternatives to be excluded would be noted in the Special
Provisions or project plans.
