2.0 METHODOLOGY

The initial geotechnical investigation comprised the drilling and sampling of 2
boreholes to depths of 1.4m and 1.5m (drilling refusal), using hand held auger
equipment. Dynamic Cone Penetrometer (DCP) testing was conducted adjacent
to the boreholes and at two additional locations.

Access for our drilling rig has recently been created and additional borehole drilling
has been undertaken. This additional field work comprised drilling and sampling 1
borehole to a depth of 6.0m and undertaking an additional hand auger to a depth
of 1.0m.

The soil classification descriptions and field tests were carried out in general
accordance with Australian Standards.

Borehole records, Dynamic Cone Penetrometer test results and a site plan showing
the test locations are appended to the report.

3.0 SITE DESCRIPTION

The site of the proposed development is located at 22 Arakoon Crescent, Sunshine
Beach.

At the time of the investigation, the site was occupied by an existing split level
residence and swimming pool. Vegetation comprised short grass cover and
gardens, with medium to large shrubs and trees at the rear of the site.

The site sloped initially steeply from the road towards the east before flattening out
behind the existing residence. The drainage conditions were considered to be fair
to good.
