Requirement for Soil Classification Reports – NSW dwellings
As part of ongoing efforts to improve building safety, NSW Fair Trading and the Building Commission NSW have clarified that for Class 1a Dwellings, Structural Engineering Plans must reference a soil classification report.
This change is all about ensuring that foundations are designed and constructed with the most accurate, site-specific information.
Here’s a quick rundown of what you need to know:
- Accurate soil data required: Structural engineers must now reference a current, site-specific soil classification report to finalise their plans for construction. This means that assuming the soil class is no longer acceptable, nor is stating soil class to be confirmed on site.
- Subdivision Reports not acceptable: Broad geotechnical reports for the purposes of the original subdivision may not be acceptable, for example in Greenfields Areas. The soil classification must be specific to the lot being developed on.
- Certification must include soil reports: Before issuing a Construction Certificate (CC) or Complying Development Certificate (CDC), building certifiers are required to verify that a compliant soil classification report has been submitted and is referenced in the Structural Engineering.
Where to get your soil classification report
A Geotech Engineer can provide a soil classification report. We would recommend liaising with your Structural Engineer to ensure the correct reports are provided for the purposes of their design.

Why early soil classification matters
We recommend securing your soil classification report as early as possible in your project planning to minimise redesigns and perhaps tenders or building quotes.
