AS 3798:2007 PDF Download

AS 3798:2007 is a standard that provides guidelines on earthworks for commercial and residential developments. It offers guidance on the specification, execution, and control testing of earthworks and associated site preparation works. However, it is important to note that this standard does not constitute a complete specification for earthworks, and the specifier should consider the applicability of these guidelines to their specific project.

This standard is not intended to be used for pavements, major roadworks, or water-retaining structures, as those types of works require special consideration. The scope of residential developments covered by this standard includes single lot development up to broad acre subdivisional development for detached or semi-detached housing. It is not intended to be sufficient for medium- or high-density residential development without the input of a qualified professional.

In the past, previous editions of this standard have been used beyond their intended scope. While some aspects of this standard may be applicable to such works with due consideration, designers and specification writers should be aware that the guidance given in this standard may not be fully applicable. In such cases, it is advisable to seek advice from a qualified professional before adopting this standard. Additionally, when the depth of filling required for works exceeds 5m, the advice of a geotechnical professional should be sought.
