6 RECORD KEEPING

It is proposed to maintain a record of the volume of excavation material and the location of
placement. The record is to be updated at the end of each working day.

It is proposed to maintain a copy of all purchase and delivery documentation describing the
quantity of lime delivered to the site

It is proposed a suitably responsible person (eg. geotechnical engineer, engineer, surveyor,
project manager, etc) supervise the lime treatment procedure to ensure the correct quantity of lime
is applied. A daily record of this activity is to be maintained.

* (f any water is retained on the site and requires discharge then a record of the water pH and any
corrective action is to be maintained by a suitably responsible person.

* Altrecords (eg. validation analysis, excavation, placement, time delivery, lime treatmentand water
quality) are to be retained for a period of five years by the project manager.

7 IMPORTANT LIMITATIONS

Significant variation in soit properties is normal, especially for low tying soits. A conservative approach is
recommended. If excavation of soil reveals material significantly different to that described in this report
then it is recommended further assessment is undertaken.

Should the design change to involve disturbance of soit with unknown properties then this should be
subject to further investigation before disturbance. The level of investigation specified by the state and
local authorities should be adopted.

This report does not address the effects of aggressive or corrosive soil upon structures or any other

services. Saline, sulphurous or acid soil (or groundwater) can have a serious corrosive effect on some
structures and this needs to be considered by an appropriately qualified person.
