Diameter Fill Material and Compaction:-
Organic material, highly reactive clays and large rocks are not suitable for use as fill. The fill is to be spread in 150mm layers and extensively
track rolled with a drott. All earthworks to be carried out in accordance with the full requirements of AS3798-1990, Guidelines for Earthworks for
Commercial and Residential Developments.
Orainage:-
The extemal finished surface surrounding the dwelling must be drained to move surface water away from the building and graded to give a slope
< of not less than 50mm over the first 1m away from the building.

450 450 aggregate size and have a nominal 80mm slump. Water must not be added to the mix to increase the slump to a value in excess of that specified.
Diameter Diameter Concrete must be placed and compacted/vibrated with good building practice. In hot and windy conditions concrete must be cured by covering with
plastic sheeting, spraying with a liquid membrane curing compound or ponding water on the top surface. The concrete must be manufactured to
