Report on Geotechnical Investigation
Proposed Residence
13 Mermaid Quay, Noosaville


1. Introduction

This report presents the results of a geotechnical investigation undertaken by Douglas Partners
Pty Ltd (Douglas) for the proposed residence at 13 Mermaid Quay, Noosaville.

The investigation was undertaken at the request of Paul Clout Building & Design Pty Limited on
behalf of the Hirsch Family in general accordance with Douglas’ proposal 229073.00.R.001.Rev0
dated 11 April 2024 and following authorisation to proceed dated 29 April 2024.

It is understood that the proposed development will comprise a two-storey residence suspended
over a basement.

The aim of the investigation was to assess the following:
•    subsurface conditions including groundwater;
•    earthworks and site preparation, including excavatability, batter slopes, suitability of site soils
     for reuse, compaction standards;
•    suitable temporary ground support options;
•    geotechnical design parameters for temporary ground support and permanent basement
     walls;
•    foundation soil reactivity in accordance with AS2870 (2011);
•    suitable foundation types, bearing pressures and estimated settlements;
•    geotechnical parameters for pavement and slab on-ground design;
•    presence and severity of acid sulfate soils (ASS); and
•    management and treatment of ASS.

The investigation comprised the drilling of two bores, followed by laboratory testing. Details of
the field work and laboratory testing are presented in this report, together with comments on the
items listed above.

This report must be read in conjunction with the notes entitled “About This Report” in Appendix A
along with any other explanatory notes and should be kept in its entirety without separation of
