WIND RATING: Region B, TC2.5, TO, PS

This report does not constitute a slope stability assessment, if the local authority deem it necessary for a slope
stability assessment to be done, a specialist Geo-technical engineer will need to be consulted.

During and after construction, site drainage must direct all surface, subsurface and roof water away from any
construction and toward stormwater run-off areas. It is the owners responsibility to ensure stable moisture
conditions around the structure at all times. Guidance can be found in the CSIRO information sheet ‘Guide to
Home Owners on Foundation Maintenance and Footing Performance’ or the QBCC booklet ‘Guide to Preventing
Structural Damage to your Home’.

The design engineer should be aware of the presence of 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 ail
considerations and satisfy themselves in this regard.

Although marine clays were not encountered in this investigation, the design engineer should always be aware of
the potential, large or small, of deep seated compressible marine clays in the area. Further in-depth investigation
would be required to determine the presence of marine clays.

This report is based on site information as at the time of investigation. A borehole sample is a very small snapshot
of the whole site volume and soil conditions can change over the site. If after excavation of the site footings, the soil
profile is significantly different to that indicated on the attached borelogs, or if the house is situated in a different

location as that marked on the site sketch or if any material change has occurred to the site, this report will become
void. This office is to be notified of such occurrences, so as a new investigation can be carried out (further charges

will apply).
