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

early as possible. Early notification often gives the Engineering Geologists the best chance
of resolving foundation problems with the most economical solution.
Structure Representatives who have problems related to foundations on projects with
oversight provided by the Office of External Liaison and Support; Externally Financed
Projects Branch, Consultant Contracts Management Branch, or Local Assistance and
Programs Section should contact the Liaison Engineer assigned to the project.
Foundation Investigation Overview
Once the Office of Structure Design begins the design of a new structure, widening,
strengthening or seismic retrofit, the Project Designer sends in a Foundation Investigation
Request to the appropriate Foundation Investigation Section. At that point an Engineering
Geologist is assigned to perform the foundation investigation.
The Engineering Geologist assigned to perform a foundation investigation for a structure
first collects as much information about the proposed site as possible. They normally
accomplish this by reviewing preliminary structure plans, previously written foundation
reports, As-Built plans, information on the historical seismicity of the area, and historical
information on the subsurface conditions in the area of the proposed structure. This
planning phase of the investigation gives the Engineering Geologist an idea of what to look
for during their field work.
Once an Engineering Geologist collects all of the preliminary information, the Engineering
Geologist lays out a boring pattern in relation to the structure's proposed foundation
locations. The main goal in establishing a boring pattern for a foundation investigation is
to collect as much subsurface information at the site as possible while making efficient use
of the available drilling equipment and personnel.
Once the boring layout is established, the Engineering Geologist directs a foundation
drilling crew during the performance of the subsurface drilling operation (to be described
later in this chapter). The purpose of the subsurface drilling operation is to collect soil
samples and perform in-situ testing at the site.
