12.0 STABILITY ASSESSMENT

    12.1 Landslip Frequency Analysis

The following landslip frequency analysis of the proposed residence, shed platforms
and immediate surrounds have been made in accordance with Taylor &
MacGregor (2001) Relative Susceptibility recommended method based on the
findings of this stability assessment.

                                                 Landslip Frequency Analysis

           Relative Frequency                        0.32

           Hazard Rating                             Low

13.0 CONCLUSION

Continued long term stability of the site is subject the development taking place in
accordance with the recommendations in this report and relevant Australian
Standards and good hillside engineering and building practices.

Refer to the attached ‘Guidelines for Hillside Construction’ for general practices for
hillside construction.

Pacific    Geotech         Pty      Ltd    provide      a    service   to   review
construction/building/development plans and it is recommended that any
designer/builder utilises this service to ensure that the proposed development is in
accordance with the intentions of this report.

It is also recommended that all earthworks, drainage, erosion protection and
foundation preparations be inspected by Pacific Geotech Pty Ltd to ensure that the
works are in accordance with the intentions of this report.

For review and inspection services, our standard rates will apply.

14.0 LIMITATIONS

We have prepared this report for the Proposed Residence at 22 Arakoon Crescent,
Sunshine Beach . The report is provided for the exclusive use of Clare Design, for this
project only and for the purposes outlined in the report. It should not be used by, or
relied upon, for other projects on the same or different sites or by a third party. In
preparing this report, we have relied upon information provided by the client or their
agents.

The results are indicative of the subsurface conditions on site only at the specific
testing locations. Subsurface conditions can change between test locations and
the design and construction should take the spacing of the testing and testing
methods adopted and the potential for variation between the test locations.
