d. Groundwater

Not reported.

4. PROPOSED MANAGEMENT

No lime treatment is proposed as the soil is not regarded as an acid sulfate soil.
However the following sections describing lime treatment have been included for use

under the following circumstances:

a) a change in soil conditions is subsequently observed from those that have been

used in this study

b) subsequent analysis of the unexpected soil material reveals the soil is acid
sulfate soil and that lime treatment is required and is the most appropriate form

of treatment.

Observation of excavated soil conditions will be performed by the building contractor or
their nominated representative. Whilst specialist acid sulfate soil experience is not
required it is recommended that a professionally qualified person (eg. architect,
engineer, surveyor, geotechnical engineer, etc) be nominated for this task. A record of

field observations should be retained with the project files.
