1.2       Method and Scope of Investigation
As part of our slope stability assessment, a desk-top study was carried out comprising a review of
published geological maps, council landslide hazard mapping and a ‘soil test’ report prepared by Ground
Drill (Ref. Job No. 18/180, dated 7 June 2018).

A walk-over assessment was carried out in order to make an appraisal of the general condition of the site
in regard to topography, drainage, vegetation cover, geology, erosion and slope stability. The walk-over
survey was carried out by an experienced geotechnical engineer from Tectonic on 19 July 2018.
The results of the desk-top study and walk-over survey are included in Section 2 below.

1.3       Qualifications of Responsible Engineer
This report has been prepared by Mr Scott Davis, an RPEQ with 10 years’ experience in geotechnical
engineering, including a number of slope stability projects on the Sunshine Coast.


2.0        DESCRIPTION OF EXISTING CONDITIONS
2.1       Geology
Available geological information1 indicates that the site is underlain by the Quaternary age Dunes, mainly
parbolic: quartz sand (refer to Text Figure 4).
