9.     Limitations

Douglas Partners Pty Ltd (DP) has prepared this report for the proposed residence at 33 Wyuna Drive,
Noosaville. The work was carried out under DP’s Conditions of Engagement. This report is provided
for the exclusive use of Rohig (Qld) Pty Ltd for this project only and for the purposes as described in
the report. It 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 DP, does so entirely at its own risk and
without recourse to DP for any loss or damage. In preparing this report DP has necessarily relied
upon information provided by the client and/or their agents.

The results provided in the report are indicative of the subsurface conditions on the site only at the
specific sampling and/or testing locations, and then only to the depths investigated and at the time the
work was carried out. Subsurface conditions can change abruptly due to variable geological
processes and also as a result of human influences. Such changes may occur after DP’s field testing
has been completed.

DP’s advice is based upon the conditions encountered during this investigation. The accuracy of the
advice provided by DP in this report may be affected by undetected variations in ground conditions
across the site between and beyond the sampling and/or testing locations. The advice may also be
limited by budget constraints imposed by others or by site accessibility.

This report must be read in conjunction with all of the attached and should be kept in its entirety
without separation of individual pages or sections. DP 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.

This report, or sections from this report, should not be used as part of a specification for a project,
without review and agreement by DP. This is because this report has been written as advice and
opinion rather than instructions for construction.

The contents of this report do not constitute formal design components such as are required, by the
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 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 DP. DP may be able, however, to assist the client in carrying out a risk assessment of
potential hazards contained in the Comments section of this report, as an extension to the current
scope of works, if so requested, and provided that suitable additional information is made available to
DP. Any such risk assessment would, however, be necessarily restricted to the geotechnical
