6      LIMITATIONS
PTG Consulting has prepared this report (or services) for this project in accordance with PTG's proposal and acceptance
received from the Client. These limitations apply whether the report was created under PTG’s own terms and conditions or
otherwise.

This report is provided for the exclusive use of SCG Consulting Engineers for the Acid Sulfate Soil investigation scope of works
and proposed residential development at 7 Noosa Parade, Noosa Heads. The report should not be used by or relied upon for
other projects or purposes on the same or other site or by a third party. Any party so relying upon this report beyond its exclusive
use and purpose as stated above, and without the express written consent of PTG, does so entirely at its own risk and without
recourse to PTG for any loss or damage. In preparing this report, PTG has necessarily relied upon information provided by the
client and/or their agents.

PTG's advice is based on information gained from limited subsurface excavations and sampling supplemented by knowledge of
local geology and experience. The accuracy of the advice provided by PTG in this report may be affected by undetected
variations in ground conditions across the site between and beyond the sampling and/or testing locations. For this reason our
reports include an interpretation of conditions between the test points. There are unknowns or variations in ground conditions
between test locations that cannot be inferred or predicted. Such variations may occur after PTG's field testing has been
completed. The precision and reliability of interpretive assessment between discrete points is dependent on the uniformity of
the subsurface strata, as well as the frequency, detail, and method of sampling or testing.

Geotechnical information represents an opinion and is based extensively on judgment of both data and interpretive assessments
or observation. This report and its associated documentation are provided explicitly based on PTG’s opinion of the site at the
time of inspection, and cannot be extended beyond this. Any recommendations or design suggestions will need to be verified
on site during project implementation or construction. Inspection and verification on site may be conducted by a suitably
qualified geotechnical consultant or engineer, and where subsurface conditions or interpretations differ from those provided in
this document or otherwise anticipated, PTG must be notified and be provided with an opportunity to review the
recommendations.

The report has been prepared by qualified personnel, and is based on the information obtained from field and laboratory testing,
and has been undertaken to current engineering standards of interpretation and analysis. The information and interpretation
may not be relevant if the development proposal is changed. If this happens then PTG Engineering will be pleased to review the
report and the sufficiency of the investigation work.

Every care is taken with the report as it relates to interpretation of subsurface conditions, and the discussion and
recommendations or suggestions relating to the geotechnical aspects of the scope of works. However, PTG Engineering cannot
always anticipate or assume responsibility for:

»   Unexpected variations in ground conditions.
»   Changes in policy or interpretations of policy by statutory authorities.
»   The actions of contractors responding to commercial pressures.

The contents of this report do not constitute formal design components, as required by Health and Safety Legislation and
Regulations, to be included in a Safety Report specifying the hazards likely to be encountered during construction and the
controls required to mitigate risk. This design process requires risk assessment to be undertaken, with such assessment being
dependent upon factors relating to the likelihood of occurrence and consequences of damage to property and to life. This, in
turn, requires project data and analysis presently beyond the knowledge and project role respectively of PTG.

This report must be read in conjunction with all of the attached documents and should be kept in its entirety without separation
of individual pages or sections. PTG cannot be held responsible for interpretations or conclusions made by others unless they
are supported by an expressed statement, interpretation, outcome, or conclusion stated in this report.
