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

Footing Foundations

Special Provisions…Review sections on earthwork, concrete structures, order of work,
etc.
Log of Test Borings…Check soil profile, groundwater, etc.
Foundation Report
Standard Specifications…Review the appropriate sections of the Standard Specifica-
tions relating to construction methods for spread footings.
Section 19-6.01: When bridge footings are constructed in embankment, the embankment
shall be constructed to the elevation of the grading plane and the finished slope
extended to the grading plane before excavating for the footings.
Section 19-6.025: When a surcharge and settlement period are specified in the Special
Provisions, the embankment shall remain in place for the required period before
excavating for footings. Also defines the minimum limits of embankment that
must be constructed before the settlement period can begin.
Section 51-1.03: Plan footing elevations are considered approximate only and the Engineer
may order changes in dimensions and/or elevations of footings as may be neces-
sary to obtain a satisfactory footing. The Contractor is responsible for costs in-
curred due to fabrication of materials or other work prior to final determination of
footing elevations. The Contractor should be notified in writing of the possibility of
foundation changes prior to commencing foundation excavation operations (refer
to Bridge Construction Memo 2-9.0).
Section 19-3.07: When the Engineer determines that it is necessary to increase the depth or
width of the footing beyond that which is shown on the plans, for a depth of up to
2 feet below the planned footing elevation or for a width of up to 3 times the
planned footing width, increased structure excavation quantities will be paid for at
the contract price per cubic yard for structure excavation.
Section 19-3.05: The Contractor shall notify the Engineer when the footing excavation is
substantially complete and is ready for inspection. No concrete shall be placed
until the footing has been approved by the Engineer.
Section 19-5.03: Relative Compaction of not less than 95% is required for embankments
under the bridge or retaining wall footings not supported on piles.
Section 19-3.04: Discusses acceptable methods for removing water from excavations where
seal course concrete is specified (or not specified). For footings supported on an
excavated surface other than rock, suitable foundation material encountered at the
planned footing elevation which has been disturbed or removed by the Contractor
shall be restored by the Contractor, at the Contractor’s expense, to a condition at
least equal to the undisturbed foundation, as determined by the Engineer. If
