The classification of a building site is one of the most important steps for owners and builders looking to construct their new home. The classification of a site is dependent on a multitude of factors, therefore it is crucial to have this undertaken by a suitably qualified person.

Our Qualified Geotechnical Engineers have been providing detailed Site Classification reports in accordance with AS 2870 in NSW, ACT and VIC for over 25 years.

Depending on the type of build, your site classification and subsequent footing design may be governed by the reactivity of the underlying clay, presence of shallow bedrock, loose sands, steep slopes, or high water tables. The presence of trees can also be a major factor in classifying a site, as the tree-induced drying effect can cause excessive movement and cracking, if the foundations are not designed accordingly.

If your building site is not connected to council sewer mains, you will need a “Land Capability Assessment” (also referred to as an Effluent Disposal Assessment) to ensure your septic system is designed appropriately for the underlying soil profile. This can be performed in conjunction with the Site Classification in order to save on travel and mobilisation costs.
