1.0      INTRODUCTION
This report details a geotechnical investigation undertaken for a proposed unit development at 31
Bottlebrush Avenue, Noosa Heads. The investigation was carried out by Tectonic for Camtegan Pty Ltd..

This report presents the results of our geotechnical investigation, incorporating a slope stability
assessment, together with geotechnical advice for the project. In summary, subject to the implementation
of the recommendations made herein, it is assessed that there would be a Low Risk of slope instability
affecting the proposed extension in accordance with the Australian Geomechanics Society “Guidelines for
Landslide Risk Management”, dated March 2007 (AGS 2007).

2.0      PROPOSED DEVELOPMENT
Architectural drawings were supplied to us with the project brief (K Architecture, Dwg. No. SK01 to SK04 [not
inclusive], Issue P1, dated 12 November 2020). We understand that the proposed development comprises a
three storey unit block constructed with masonry blockwork, with a partial inground semi-basement for
carparking and storage. No earthworks plans were provided but based on the layout details provided it is
anticipated earthworks will include cuts for the basement level of up to about 3 m deep in in the rear,
northern part with the excavation daylighting in the central/southern part. Only minor filling is expected to be
required up to say 1 m in height to form finished surface levels.

The property has existing connections to town water supply and sewerage. Extracts from the proposed
layout drawings are shown in Text Figure 1 below.
