4.0 GEOTECHNICAL MODEL

The subsurface profile encountered in the boreholes consisted of initially very loose
to loose sands overlying medium dense to dense sands to the termination of testing.
In Borehole 1, 600mm of very loose gravelly sand was encountered.

The density of the sand has been interpreted on the basis of the DCP testing results.

Detailed borehole record sheets are appended to this report.

Groundwater or subsurface seepage was not encountered in the boreholes at the
time of drilling.

5.0 EARTHWORKS AND SITE PREPARATION CONSIDERATIONS

Earthworks are expected to comprise of a cut operation of up to 4m to create an
underground plant room and water tank. Minor filling removed from the excavation
and primarily adjacent Arakoon Crescent is expected.

Consideration should be given to maintaining the stability of the excavation
immediately adjacent Arakoon Crescent during earthworks.
