2.      EXISTING CONDITIONS



        2.1    Local Geology

Regional geological maps indicate that the site is underlain by Quaternary age Holocene parabolic
dunes comprised of predominantly quartz sands.

These general conditions were confirmed by the site classification boreholes and during the site
walkover.

Three (3) boreholes were undertaken at the site to assess subsurface conditions. Auger refusal on
rock was not encountered in any of the boreholes which were terminated at 3.0m depth below
existing surface level.

A summary of the site investigation undertaken by Global Testing on 22 August 2013 is provided
below.

Sub-surface conditions interpreted from boreholes at the site indicate a consistent soil profile of
Aeolian sands from surface to approximately 3.0m depth where boreholes were terminated.

Below 3.0m depth, additional data on the in-situ density of soils was collected/interpreted using a
Dynamic Cone Penetrometer (DCP). DCP testing was undertaken adjacent to each borehole
location to maximum depths of 4.3m.
