8.0 EARTHQUAKE SITE CLASSIFICATION
It is recommended that the following coefficients be adopted for the design of the structure on
this site according to AS 1170.4-2007 Structural design actions Part 4: Earthquake actions in
Australia :-

          Hazard Factor (Z) = 0.08 - Table 3.2 - Noosa
          Site sub-soil class, depending on founding level for the main structure shall be (Refer
           Section 4 of code):-
                      Class De – Deep Soils Site


9.0 LIMITATIONS
We have prepared this report for the use of Wessel Petroleum Pty Ltd, for design purposes in
accordance with generally accepted geotechnical engineering practices. No other warranty,
expressed or implied, is made as to the professional advice included in this report. This report
has not been prepared for use by parties other than Wessel Petroleum Pty Ltd; it may not
contain sufficient information for purposes of other parties or for other uses. Please note that
any third party relying on the information contained in this report for any purpose whatsoever
does so entirely at its own risk, and any duty of care to that third party is excluded.

Any interpretation or recommendation given by Soil Surveys Engineering shall be understood to
be based on judgement and experience and not on greater knowledge of the facts than the
reported investigations would imply. The interpretation and recommendations are therefore
opinions provided for our Client’s sole use in accordance with the specific brief. As such they do
not necessarily address all aspects of ground behaviour on the subject site. Information
provided by others has been taken in good faith, but no liability can be accepted for information
provided by others.

Your attention is drawn to ‘Appendix A’, ‘Notes Relating to this Report’. Interpretation of factual
data given in this report is based on judgement, not a greater knowledge of facts other than
those reported.

Interpretation of the information shown on the logs, and its application to design and
construction, should therefore take into account the spacing and depth of boreholes, the
method of drilling, the frequency of sampling and testing and the possibility of other than
“straight line” variations between the boreholes. Subsurface conditions between and below
boreholes may vary significantly from conditions encountered at the borehole locations.

Please note, if following detailed design, the founding depth of any footings or piers/piles is
within 3B (B = footing width/pier diameter) above the termination depth of the
boreholes/pits/CPTU or if any excavations extend below the borehole/pit/CPTU termination
levels, then Soil Surveys Engineering should be contacted immediately.

If the above were to occur then the geotechnical data in this report should be considered
preliminary only; additional investigation is likely to be required.

In the event that conditions encountered on site during construction appear to vary from those
expected from the information contained in the report, the Company strongly recommends that
it immediately be notified. Most problems are more readily resolved when conditions are
