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

Foundation Investigations
1-8
Applicability of the Log of Test Borings
and Foundation Report to the Contract
It is very important for Structure Representatives, as well as all Structure Construction
employees, to be aware of how the Standard Specifications interpret the applicability of the
Log of Test Borings, Foundation Report, or any record of subsurface investigation produced
by the State. Section 2-1.03 of the Standard Specifications describes how these documents
should be viewed by all contractors performing work for the State.
Section 2-1.03 of the Standard Specifications states that the Contractor has an obligation
to examine the site of the work, the plans, and the specifications. From this examination,
contractors are to make their own determination as to what conditions they may encounter
while doing the proposed work. This section also states that bidders can inspect any records
compiled by Caltrans, but the use of this information is only for the purpose of study and
design and that they are not part of the contract documents. Caltrans assumes no responsi-
bility as to the sufficiency or adequacy of any of its investigations and this section states that
there is no warranty or guaranty that any conditions indicated by a subsurface investigation
performed by Caltrans are representative of the conditions throughout a construction site.
This section also describes the Log of Test Borings and any other geotechnical data obtained
as being Caltrans’ opinion as to the character of the materials encountered during its
investigations at the site of the work.
Section 2-1.03 also very clearly states that contractors should make whatever independent
investigations that they feel are necessary to inform themselves of the conditions to be
encountered. Contractors should only be using the Log of Test Borings and any other
records of subsurface investigations compiled by Caltrans to supplement their own site
investigations.
Basic Soil Properties
In order to understand and interpret a Log of Test Borings and Foundation Report, it is
important to have a basic understanding of the different types of soils that may be encoun-
tered during foundation investigations.
There are a number of soil classification systems used in the engineering industry. Most of
these systems are based on those properties which are most important in the phase of
engineering for which the classification was developed.
