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

Contract Administration
3-6
On projects involving Cast-In-Drilled-Hole (CIDH) concrete piles, the Contractor should be
notified in writing that CIDH piles must penetrate at least to the specified tip elevation
shown on the plans or as ordered by the Engineer and that no additional payment will be
made for piles that penetrate below the specified or ordered tip elevation. Any ordered
change by the Engineer must be in writing.
In accordance with Section 49-4.03 of the Standard Specifications, the Contractor has the
option to submit a proposal to increase the diameter and revise the tip elevation of CIDH
piling. In this instance, the Contractor is paid for the theoretical length of the specified pile
to the specified tip elevation.
Bridge Construction Memo 9-1.0 covers As-Built plans as a part of the final records and
reports. As-Built plans should provide an accurate portrayal of what was constructed. This
information is important when changes are made to the structure after original construc-
tion is complete. For example, footing overpours are often not shown on the As-Built plans
and become a problem during the construction of footing seismic retrofits. Other problems
have resulted from existing shoring and utilities that are moved or left in place. These have
added to the cost of projects involving improvements to existing structures.
Currently many contractors are submitting claims regarding Differing Site Conditions.
These claims are usually the result of problems with foundation work. Accurate As-Built
plans can sometimes help to prevent such claims.
According to Section 5-1.116 of the Standard Specifications, timely notification, documen-
tation, and response is of the utmost importance. Each claim for differing site conditions is
handled per project or individually. Be familiar with the information discussed in Chapter 1
of this manual and you may be able to avoid such claims. Remember that the Contractor is
not the only person who can find differing site conditions.
