What is AS 2870?

AS 2870 is a technical standard used in the construction industry. It provides guidelines and requirements for the design and construction of residential slabs and footings in Australia. This standard ensures that buildings have stable foundations that are suitable for the local soil conditions.

Key Requirements of AS 2870

To comply with AS 2870, several key requirements need to be met during the design and construction process. Firstly, a geotechnical investigation must be conducted to assess the soil type and its characteristics. This helps determine the appropriate footing system to be used.

Based on the findings of the geotechnical investigation, the standard defines several classes of soil types, each requiring different foundation systems. For example, Class A and S sites have stable soil conditions, while Class M and H sites may require more complex footing designs.

In addition to soil classifications, AS 2870 also sets out minimum slab and footing dimensions. These dimensions are based on factors such as the building loads, soil classification, and site-specific conditions. Adhering to these dimensions ensures the structural integrity of the foundations.

Benefits of Using AS 2870

The use of AS 2870 brings several benefits to both builders and homeowners. One of the main advantages is the assurance of a structurally sound foundation. By following the standard's guidelines, the risk of foundation failures due to incorrect design or construction practices is significantly reduced.

In addition, AS 2870 provides a common language for engineers, architects, and builders to communicate and collaborate effectively. The standard ensures that all parties involved in the construction process are aware of the required design parameters, allowing for smoother project execution.

Moreover, complying with AS 2870 helps in achieving compliance with building codes and regulations. Many local authorities require adherence to this standard as a part of the approval process for construction projects. By following AS 2870, builders can avoid delays and complications during the permitting stage.

Conclusion

AS 2870 is an essential technical standard for the construction industry in Australia. It provides guidelines for the design and construction of residential foundations, ensuring stability and structural integrity. By complying with AS 2870, builders can mitigate risks, improve communication, and streamline the approval process. Ultimately, using this standard contributes to the overall quality and safety of buildings.
