Soil Testing (Site Classification) For Foundation Construction
Soil Tests (site classification) for residential dwellings, industrial, commercial and institutional buildings, be they part of a subdivision or an individual allotment or building extension are required to assess the subsurface conditions and therefore enable design of appropriate foundations. SITE Geotechnical regularly undertake these types of investigations in accordance with the Australian Standards;
AS2870-1996: "Residential Slabs and Footings - Construction" and
AS1726-1993: “Geotechnical site investigations”
Your site is namely classified based upon the expected movement of the foundation soils - generally related to the capacity of the soil to shrink and swell.
The following classifications may be typically given:
CLASS 'A' - Little or no ground movement
CLASS 'S' - Slightly reactive sites
CLASS 'M' - Moderately reactive sites
CLASS 'H' - Highly reactive sites
CLASS 'E' - Extremely reactive sites
CLASS 'P' - Problem site

But if any of you lacks wisdom, let him ask of God, who gives to all generously and without reproach, and it will be given to him.
