1.0 Introduction
Geotech Engineering Pty Ltd (GE) was commissioned to undertake a geotechnical investigation
for the Proposed Residnetial Dwelling located at 38 Avocet Parade, Peregian Beach.


This report outlines the results of the investigation, laboratory testing, analysis and interpretive
reporting on the following items:
• All factual information resulting from the investigation (investigation methodologies,
   detailed desktop review, test location plans, bore logs);
• Summary of subsurface conditions and adopted subsurface conditions including
   groundwater;
• Stability assessment in accordance with AGS guidelines;
• Earthworks and site preparation comments;
• Site movements;
• Foundation recommendations and allowable bearing pressures;
• Hillside construction comments

This report must be kept in entirety.


2.0 Site Details

2.1 Detailed Description
The site can be described as typical for a residential allotment that has triggered slope stability
requirements. The site has varying grades falling away to the east at relatively moderate grades
broadly speaking initially and then becoming gently graded to the limit of the allotment at the
eastern boundary. The photograph shown on the title page of this report gives a good
indication of site conditions at the time of the walkover assessment .

2.2 Geology
Referencing available geology datasets available from QLD Globe, the site is in an area
underlain by Quartenarly aged alluvial deposits which typically comprises sands, clays, gravel,
and silt. The encountered subsurface conditions broadly agree with the expected geology.

2.3 Groundwater
During the walkover assessment, no groundwater was observed across the entire site. It must
be noted that groundwater is transient and seasonal in nature. Given this, the time at which
the walkover assessment was undertaken may not indicate worst case conditions.

2.4 Vegetation
During the walkover assessment, a variety of vegetation ranging from small shrubs to mature
trees were observed. The mature trees were all observed to be typically vertical with no
misshapen or curved trunks. Misshapen or curved trunks are usually good indicators for
previous slope instability.
