6.2.2 ‘ompacti ‘oc 1S ecifications

While it is noted that significant filling is not anticipated, additional filling should be carried
‘out in accordance with AS.3798-1996, and the following should be noted:

* The insitu soils, where free of organic and deleterious material, may be used for
structural fill provided the moisture content of the soils on placement approximates
the optimum moisture content required for compaction. This may require
conditioning to bring the soils to optimum.

+ Any imported fill, if needed to make up earthwork deficiencies, should have a soaked
CBR of not less than 10 percent and a maximum aggregate size of not greater than
75mm with not more than 20% greater than 20mm.

Provided the placement moisture content of the imported fill or select insitu material
approximates the optimum moisture content for compaction, suitable compaction should
be achievable using a large static smooth drum roller. Guidelines for minimum relative
compaction values for insitu soils and imported fill for the building and pavements are -
presented in Table 3.

6.2.3 Excavation Characteristics

It is anticipated that excavations will consist of the following:-

* Bulk Cuts - for site stripping and excavation to construct basement levels.

Excavations on site should be within the capabilities of light plant, small dozer (Cat D4C
or similar) in bulk cuts and a medium sized backhoe (Case 580 or similar) or small
excavator (12t - 15t) in trenching, based on the investigation findings. Should substantial
excavations be required in these soils, larger plant could be budgeted to expedite
workings.
