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 at Aitken Rowe Testing Laboratories Pty Ltd 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 is are also a major factor in classifying a site, as the tree-induced drying effect can lead to early failure, 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. The application of effluent to land requires careful consideration and expertise, with new builds under closer scrutiny than in days past. ARTL consults with all local councils to ensure compliance during the design phase. We also regularly undertake assessments of existing systems, so if you have any questions about your septic system, please don’t hesitate to call!

ARTL uses proprietary nutrient and water balance modelling, developed with interpolated weather data over 25 years. This allows our Geotechnical Engineers to provide a site specific report with detailed recommendations to ensure a cost-efficient and long-lasting septic system whilst protecting the environment.
