         The use of water or mud as a drilling       Requirements could range from:
          fluid will mask any groundwater inflow.
          Water has to be flushed from the hole          i.    a site visit to confirm that conditions
          and drilling mud must be washed out                  exposed are no worse than those
          of the hole or ‘reverted’ chemically if              interpreted, to
          water observations are to be made.            ii.    a visit to assist the contractor or other
More reliable measurements can be made by                      site personnel in identifying various
installing standpipes from which ongoing                       soil/rock types such as appropriate
monitoring can be undertaken.                                  footing or pier founding depths, or

Fill

The present of fill materials can often be
determined only by the inclusion of foreign
objects (e.g. bricks, steel ,etc.) or by distinctly
unusual colour, texture or fabric. Identification
of the extent of fill materials will also depend on
investigation methods and frequency. Where
natural soils similar to those at the site are used
for fill, it may be difficult to reliably determine
the extent of the fill.

Laboratory Testing

Laboratory testing is carried out in general
accordance with Australian Standard 1289
‘Methods of Testing Soil for Engineering
Purposes’.

Site Anomalies

In the event that conditions encountered on
site during construction appear to vary from
those which were expected from the
information contained in the report, the
company requests that it immediately be
notified. Most problems are much more readily
resolved when conditions are exposed than at
some later stage.

Review of Design

Where major civil or structural developments
are proposed or where only a limited
investigation has been completed or where the
geotechnical conditions/constraints are quite
complex, it is prudent to have a design review.

Site Inspection
