1 REPORT SCOPE
This report presents the results of the interim geotechnical investigation carried out by PTG Consulting (PTG) for the
proposed residential development to be located at 20 William Street, Noosaville. The investigation was commissioned
by Tom Harrington on behalf of SCG Consulting Engineers for Ross Palazzesi.

Preliminary sketches and communication provided via the client indicate that the final usage of the site will comprise
a three-story duplex residential building with a single-level basement.

The geotechnical investigation included three (3) auger boreholes with dynamic cone penetrometer (DCP) testing
and laboratory testing of selected samples undertaken in general accordance with PTG’s proposal, ‘AS 1726:2017-
Geotechnical Site Investigations’ and ‘AS 1289-Methods of Testing for Engineering Purposes’.

This report includes a description of the fieldwork procedures, the results of the fieldwork and laboratory testing, and
reporting on the following:
» Site classification and predicted ground surface movement (ys) in accordance with ‘AS 2870:2011’;
» Allowable bearing pressures for high level footings and estimated settlements;
» Suitable pile types, ultimate base bearing, skin frictions and estimated settlement (if required);
» Exposure classification for concrete or steel pile design in soil;
» Presence of Acid Sulfate Soils (ASS); and
» Any other geotechnical issues identified that would need management (if any).



2 PROJECT DESCRIPTION
Based on the concept sketches provided the development is understood to comprise:
» Demolition of the existing residence;
» Construction of a new three level residential duplex building;
» Boxing out and construction of new pavement driveways; and
» Installation of underground services from the boundary to the building.
