Lot (Site) Classification Reports
If you're planning to build a new home or extend your existing one, a lot classification report is essential. It provides a detailed soil analysis, outlining the conditions and profiles of your site. Understanding your soil classification ensures that your home's foundation is designed to withstand ground movement, providing stability and longevity.
Why is a Lot Classification Report Important?
The foundation of any building is designed based on an assessment of the subsurface conditions. Whether it’s a residential, commercial, industrial, or institutional project, proper soil classification helps prevent costly structural issues in the future.
Soil Classifications Explained:
- Class ‘A’ – Little or no ground movement
- Class ‘S’ – Slightly reactive sites
- Class ‘M’ – Moderately reactive sites
- Class ‘H1’ – Highly reactive clay sites with significant ground movement due to moisture changes
- Class ‘H2’ – Very highly reactive clay sites with extreme ground movement from moisture changes
- Class ‘E’ – Extremely reactive sites
- Class ‘P’ – Problem sites requiring special consideration
A site classification report is prepared in accordance with Australian Standards AS 2870-2011 (Residential Slabs & Footings) and AS 1726-2017 (Geotechnical Investigations).
How Does This Help Your Project?
This report provides crucial information for structural engineers to design the right foundation for your home. Builders can also anticipate potential site challenges, such as:
- Rock formations
- High water tables
- Soft or collapsing soils
Without this report, engineers and builders are left to guess the soil conditions, which can lead to unexpected issues during construction.
Additionally, wind classification is included in lot classification reports, assisting engineers and frame & truss manufacturers in designing structures suited to your site's conditions.
Affordable & Essential for Construction
A Lot Classification Report is a small investment that plays a major role in the success of your construction project.
