Information

Important Information about your Report

As a client of Wagner Soil Testing Pty Ltd you should know that site subsurface conditions cause more construction
problems than any other factor. These notes have been provided to help you interpret and understand the limitations of

your report.

Your report is project specific

Your report has been developed on the basis of your
unique project specific requirements as understood by
Wagner Soil Testing and applies only to the site
investigated. Project criteria typically include the general
nature of the project; its size and configuration; the location
of any structure on the site; other site improvements; the
presence of underground utilities; and the additional risk
imposed by scope-of-surface limitations imposed by the
client. Your report should not be used if there are any
changes to the project without first asking Wagner Soil
Testing to assess how factors that changed subsequent to
the date of the report affect the report’s recommendations.
Wagner Soil Testing cannot accept responsibility for
problems that may occur due to changed factors if they are
not consulted. Our report does not take into account any
existing filled ground or any other unforeseen subsurface
conditions that may change anticipated site classification.

Subsurface conditions can change

A geotechnical engineering report is based on conditions
that existed at the time the study was performed. Do not
rely on a geotechnical engineering report whose adequacy
may have been affected by: the passage of time; by man-
made events, such as construction on or adjacent to the
site; or by natural events, such as floods, earthquakes, or
groundwater fluctuations... Always contact Wagner Soil
Testing before applying the report to determine if it is still
reliable. A minor amount of additional testing or analysis
could prevent major problems.

Interpretation of factual data

Site assessment identifies actual subsurface conditions
only at those points where samples are taken and when
they are taken. Data derived from literature and external
data source review, sampling and subsequent laboratory
testing are interpreted by geologists, engineers or scientists
to provide an opinion about overall site conditions, their
likely impact on the proposed development and
recommended actions. Actual conditions may differ from
those inferred to exist, because no professional, no matter
how qualified, can reveal what is hidden by earth, rock and
time. The actual interface between materials may be far
more gradual or abrupt than assumed based on the facts
obtained. Nothing can be done to change the actual site
conditions which exist, but steps can be taken to reduce the
impact of unexpected conditions. For this reason, owners

CONSTRUCTION

MATERIALS

should retain the services of Wagner Soil Testing through
the development stage, to identify variances, conduct
additional tests if required, and recommend solutions to
problems encountered on site.

Your report will only give preliminary
recommendations

Your report is based on the assumption that the site
conditions as revealed through selective point sampling are
indicative of actual conditions throughout an area. This
assumption cannot be substantiated until project
implementation has commenced and therefore your report
recommendations can only be regarded as preliminary.
Only Wagner Soil Testing, who prepared the report, is fully
familiar with the background information needed to assess
whether or not the report's recommendations are valid and
whether or not changes should be considered as the
project develops. If another party undertakes the
implementation of recommendations of this report there is a
risk that the report will be misinterpreted and Wagner Soil
Testing cannot be held responsible for such
misinterpretation.

Your report is prepared for specific purposes and
persons ;

To avoid misuse of the information contained in your report
it is recommended that you confer with Wagner Soil Testing
before passing your report on to another party who may not
be familiar with the background and purpose of the report.
Your report should not be applied to any project other than
that originally specified at the time the report was issued.

It is a requirement that the client contacts Wagner Soil
Testing Pty Ltd when the exact position of the proposed
building is confirmed so we can check if our Boreholes fall
in the footing area [our borelogs are only presumed
indicative of the whole area until this is confirmed]. In the
case of a cracked house investigation more testing may be
required to conclude all possible causes of settlement and
or movement. Initial drilling and lab testing may only identify
some of the causes of the problem. Wagner Soil Testing
should be contacted when additional testing is required. It
is a company policy that Wagner Soil Testing are contacted
if the development (including any portion and/or envelope)
is sold and/or changes title as the report is only for the use
of our direct client. If the development is sold and/or
changes title Wagner Soil Testing must be contacted and
subsequently will carry out a comprehensive site inspection
— evaluation at no cost to ensure the preliminary report is
relevant and no changes whatsoever have been made.
