                                     SITE CLASSIFICATION REPORT

 CLIENT: Permabuild                                                        CSI JOB NUMBER: 15928
 SITE ADDRESS: Unit 2, 6 Martin St, Peregian Beach                         DATE TESTED: 28/03/2024
 TEST METHOD: Hydraulic Rig                                                TESTED BY: BAC
                                                                           GUIDED BY AS2870-2011

VEGETATION: Established lawns and gardens. Large trees.
TOPOGRAPHY: Hilly area. Sand dunes. Fill and sloping block. Good drainage.
STRATA SUMMARY: Sand fill over natural sand.
CROSS FALL: 2-7%
COMMENTS: Boreholes located where accessible and to minimise risk to underground services.

In accordance with AS2870-2011 and based on the field information at the time of the investigation carried out on
the above address,


The site has been classified as an “S” Classification 0mm < Ys <= 20mm, if the construction is founded into
a natural stratum with a bearing capacity that is greater or equal to 100 kpa, with no underlying soft layers, or to
an allowable bearing capacity as specified by a qualified Geotechnical and/or Structural Engineer.
If these conditions are not met the site would be classified as a Class “P”, due to
     • layers of soil with an indicative bearing capacity of < 50 kpa
     • layers of uncontrolled sand fill > 800mm
This classification is based on a fill certificate not being available, however if a fill certificate can be supplied
please contact CSI Soil Testing who may be able to re-classify the site.


The design engineer should be aware:
   • That there are trees on or near the site and that they may have an effect on the performance of the
       footings/slab, whilst in place and after removal. The design engineer should take all considerations and
       satisfy themselves in this regard.
   • Of the potential differential swelling and settlement possible when attaching a new construction to an
       existing structure and that this may have an effect on the performance of the footings/slab. The design
       engineer should take all considerations and satisfy themselves in this regard.


This site classification is for the design of a footing system for a single dwelling house, townhouse or similar
structures as specified in AS2870-2011.


This report is a site classification and does not constitute a Geotechnical Engineers assessment and/or slope
stability assessment, if the owner/builder/local authority/structural engineer deems it necessary for a full
geotechnical assessment and/or slope stability assessment to be done, a specialist Geo-technical engineer will
need to be consulted.


This report does not constitute a mine shaft subsidence assessment. If the local authority deems it necessary,
application to the Department of Mines and Energy is necessary for a specific site report.

Before, during and after construction, site drainage must direct all surface, subsurface and roof water away from
any construction and toward stormwater run-off areas. The site drainage should be checked before building to
ensure stable moisture conditions. Excessive moisture can reduce the strength of the soil. Moisture change can
cause shrink-swell movements of the soil. It is the owners or principal contractors’ responsibility to always ensure
stable moisture conditions around the structure. Guidance can be found in the CSIRO information sheet ‘Guide to
Homeowners on Foundation Maintenance and Footing Performance’ or the QBCC booklet ‘Guide to Preventing
Structural Damage to your Home’.


This report is based on site information as at the time of investigation only and does not consider any event,
whether by human intervention and/or by nature that occurs after this visit, which affects the results and findings
of this investigation and report. A borehole sample is a very small snapshot of the whole site volume and Soil
conditions can change rapidly over a very short distance, both vertically and horizontally, and with variations
caused by time, nature, and nearby developments. Results are therefore used as a guide in determining the
whole foundation conditions of the site. Before building, if the site conditions have changed and/or if after
excavation of the site footings, the soil profile is significantly different to that indicated on the attached bore logs,
or if the construction is situated in a different location as that marked on the site sketch or if any material change
has occurred to the site whether by human intervention and/or by nature, this report will become void. If the
report becomes void, this office is to be notified of such occurrence and it is a CSI recommendation that a new
investigation can be carried out prior to design/construction (further charges will apply).
