SITE INVESTIGATION

As with all site investigations we assume that the fundamental principles of good
developmental construction, earthworks or such were not overlooked, and were
carried out with the consistent application of ‘best practice’ techniques at each stage
as these factors are of great consequence. We also presuppose that the fundamental
principles of good construction will not be overlooked, and will be carried out with
the consistent application of ‘best practice’ techniques across the site as these factors
are also of great consequence.

The fieldwork undertaken for our site investigation included the following;

detailed subsoil investigation recording characteristics and limitations,

a comprehensive site assessment to record topography, geography and geology,
soil observation boreholes (75-100 mm dia. Jarret style hand augers),
penetrometer testing with 9kg Dynamic Cone Penetrometer (DCP),
classification and testing of hand collected soil samples.

(The test locations were not professionally surveyed and should be considered approximate)
(All fieldwork performed in accordance with the relevant Australian Standards and Codes)
(All boreholes backfilled in accordance with Occupational Health and Safety regulations)

FIELD TEST LIMITATIONS

The soil profiles reported should generally be representative of the soil conditions across this
site. In some cases soil conditions can change dramatically, and can change over short
distances. If site works reveal soil conditions that are different from those shown in the
attached data, the evaluator must be informed immediately as changes may be necessary.

CLIENT SUPPLIED INFORMATION

This site investigation and classification has been undertaken in accordance with AS
2870 ‘Residential Slabs and Footings'' The Queensland Building & Construction
Commission's (QBCC) 'Rectification of Building Work Policy’ has a requirement for
the following information to be supplied to us, and that we consider this information
in determining the site classification. This information includes, but is not limited to;
Property description and site address,

Evidence to ensure site is correct (e.g. Survey Plan, Registered Plan, etc),

Survey plan delineating contours, trees, existing developments, etc,

Land searches, including such information as flood lines, easements, covenants,
underground services and infrastructure, etc,

Any previous geotechnical work, e.g. original contour survey, and the limits of
prior subdivisional or developmental cutting and filling, service lines etc.

The known extent of further developmental or construction earthworks

In this instance and at the time of our commission, we have considered the
information supplied to us by the client. Should the client or his agent have omitted to
supply us with the QBCC required information or supplied us with incorrect
information our assessment may be irrelevant and/or inappropriate. However, should
this information become available we would be pleased to amend our report
accordingly, if, and as necessary. We do not take responsibility for the consequences
in such cases and may incur additional costs if as a result; more testing or re-writing
is necessary.
