Frequently asked

AS 2870 Site Classification questions

Is a soil test the same as a site classification?+

People often use “soil test” for an AS 2870 site classification. The work normally includes field investigation and may include laboratory testing, followed by an engineering classification report.

Can you classify a site with existing buildings?+

Often yes, subject to access and the proposed work. Existing paving, structures and services can limit test locations, so plans and access photos help us scope the investigation.

Who uses the report?+

The structural engineer or footing designer commonly uses the classification and site information when designing residential footings and slabs.
