economic constraints. If soil conditions differ from those of the log sheet attached during excavation or construction,
please notify this office immediately for further inspection and recommendations.

The Local Authority and/or property owner/builder should check their records and advise this office of any elements
that they are aware could influence the site classification, eg. Cutting and filling of the site.

Our definition of rock in this case is the same as the definition in AS2870 “A strong material including shaley material
and strongly cemented sand or gravel that does not soften in water. Materials that cannot readily be excavated by a
backhoe may be taken to be rock”. Therefore, in our opinion, a backhoe using a 300mm wide bucket will have
difficulty in excavating below the depth where we were unable to penetrate. We assume that the backhoe is in good
condition and is similar in power to a Case 580 series (or a MF50).

In writing this report we have considered all the information supplied to us by our client. Should the client or his agent
have omitted to supply us with relevant information, our report may be irrelevant and/or inappropriate. We do not take
responsibility for the consequences in such cases, and we will make an additional charge if as a result, more testing or
re-writing of the report is necessary.

This report has not taken into consideration the long term effect of any previous, current or potential subsurface work
by mining companies. At the time of writing this report, neither our client, (or his agent) or the Local Authority had
made us aware that surface mining may be affecting this allotment in any way.
