1.0     INTRODUCTION
As requested by JFP Urban Consultants Pty Ltd, on behalf of Cambooya Pty Ltd, Core Consultants Pty Ltd
(Core) has carried out a geotechnical investigation and slope stability assessment for a proposed mixed-use
development at 36-38 Duke Road, Sunshine Beach.

2.0     PROPOSED DEVELOPMENT
We understand that the proposed development is to comprise a three to four-storey building that is to be
terraced up the sloping ground surface, as shown on Image 1. The lower level on the southern two thirds of
the site is anticipated to require excavations of up to about 3 m depth and retention of the upslope ground.
The construction of the development will require the demolition of the existing structure and will need to be
constructed so as to not impact the adjacent structures. The existing building to the east is believed to have
a basement level at or close to the basement level of the proposed building on the subject site.
Design drawings and foundation loads have not been provided at the time of writing; however, it is
anticipated from similar type developments that foundation working loads for a four-level building will be in
the order of about 1,500 kN to 2,500 kN under columns (depending on the column/wall spacing
configuration).

3.0     SITE DESCRIPTION
The site has frontage to Duke Street along the southern end of the property boundary, with Douglas Lane
along the northern property boundary. Mixed-use retail and residential buildings are situated to the east and
west.
The existing building is positioned on the southern half of the site. The topography on the northern half of the
site generally comprises two breaks in slope, with measured slope angles of between 3° and 19° towards the
south-east. A small retaining wall is located just to the north of the existing building.
Photographs 1 to 3 show the general site conditions at the time of our investigation. Figure 1 in Appendix A
displays the site layout.
