Lot / Site Classification Services
Atlas Engineering and Technology Group delivers thorough site and lot classification services throughout Sydney.
Our geotechnical engineers assess your site's soil conditions to classify the ground according to Australian Standards (AS2870). This determines how reactive the soil is and how much movement might occur over time.
What is Lot/Site Classification?
Site classification evaluates the soil's reactivity and potential movement, which directly impacts foundation design requirements. This classification is essential for:
- New residential construction
- Home extensions or renovations
- Commercial and industrial developments
- Ensuring compliance with building codes and regulations
Classification Types
According to Australian Standard AS2870, sites are classified into these categories:
- Class A - Stable, non-reactive sites with little or no ground movement
- Class S - Slightly reactive clay sites with minimal ground movement
- Class M - Moderately reactive clay sites
- Class H - Highly reactive clay sites with significant ground movement
- Class E - Extremely reactive sites with very high ground movement potential
- Class P - Problem sites (filled, mine subsidence, landslip, collapsing soils)
Our Process
- Site inspection and assessment
- Soil sampling and borehole drilling as required
- Laboratory testing of soil samples
- Analysis of soil reactivity and movement potential
- Classification report with foundation recommendations
- Professional consultation to explain findings
