GEOTECHNICAL SERVICES - 27 ATTUNGA HEIGHTS, NOOSA

Dear Pamela,
This letter report presents the results of a geotechnical assessment carried out by Core Consultants Pty Ltd
(Core) for a proposed development at the above site. The work was carried out in accordance with our
proposal Q000205-001-L-Rev0.
This office, previously operating as Golder, carried out a geotechnical investigation for a proposed
development on the site in 2003 (refer report 03682248-001, dated November 2003, attached). The proposed
development layout has since been amended. The 2003 geotechnical investigation covers much of the current
development layout, with the exception of the proposed development along the western boundary of the site.
Proposed development
We understand that the proposed development comprises a 19-unit residential development, as shown on
Innovative Planning Solutions drawing set SD.01 to SD.10 (D), dated 3 September 2015.
Fieldwork
To supplement and confirm the existing geotechnical report, the following geotechnical investigation was
undertaken:

       Site walk-over assessment
       Hand-auger borehole drilling
       Dynamic cone penetration (DCP) testing

The fieldwork was undertaken on 23 September 2015.
A senior geotechnical engineer from Core reviewed the 2003 geotechnical report, and then undertook a site
walk-over to assess potential changes to the site since the 2003 geotechnical investigation.
Two hand-augered boreholes (designated BH1 and BH2) were drilled in the western portion of the proposed
development footprint, to depths of 1 m and 0.9 m below ground level, respectively.
Dynamic cone penetrometer (DCP) testing was carried out adjacent to each borehole, to depths of 3.6 m and
3.1 m BGL, respectively.
Borehole locations were recorded in the field using a handheld GPS unit. Borehole locations are shown on the
attached Figure 1.
Reports of boreholes are attached, together with explanatory notes.
Site conditions at the time of our investigation are shown on the attached Photograph 1.
