1.0 INTRODUCTION

This report contains the results of the geotechnical investigation and provides advice
and recommendations relating to the following:

     •     Subsurface conditions in accordance with AS 1726-2017
     •     Groundwater conditions
     •     Indicative site classification for hydraulic design in accordance with AS 2870-
           2011
     •     Earthworks recommendations including:
                 o     Suitability of cut for use as fill
                 o     Compaction standards
                 o     Stripping depths
                 o     Trafficability
                 o     Excavatability
                 o     Safe temporary batter slopes for cuts
                 o     Fill batter slopes
     •     Retention considerations
     •     Retaining wall design parameters
     •     Earthquake/liquefactions considerations
     •     Foundation Recommendations including:
                 o     High-level and deep support options
                 o     Bearing capacity and skin friction design values
                 o     Predicted settlements
                 o     Preliminary raft design parameters
     •     Construction Considerations
Proposed Development

It is understood that the proposed development is to consist of the construction of a
double-storey residence, with a single level basement. Excavations are expected to
comprise cuts of up to 3m to create the proposed basement.

The proposed development is indicated below.
