6.1    Site Classification

Site classification in accordance with AS 2870 is used to assist in the selection of standard footings
for residential buildings up to two-storeys and other buildings of similar size, loading and
flexibility.

In the absence of documentation to confirm that the existing fill was placed in a controlled
manner to a specified engineering standard, the fill is deemed to be ‘uncontrolled’. In addition,
given the presence of relatively loose sand with an allowable bearing capacity of less than 100 kPa,
the site would then be classified as ‘Class P’ (problem site) requiring design by engineering
principles.
