The Standard applies to site classification and footing system design for houses and the like, extensions and outbuildings.The recommendations in the Standard were developed from research and experience in the design and performance of house footings and slabs, but there is no reason why they cannot be applied to other similar structures. The similarities should be in the size, the loading and the type of construction.Different building practices, such as the use of contraction joints in concrete slabs, are used in large non-residential structures but the Standard makes no design provision for these. As well, it is unlikely that the Standard will be appropriate for industrial floors, except for the lightest applications.The Standard has been based on methods of construction that are generally well accepted throughout Australia. Nonetheless, footing design is a developing field and it is possible that new or locally effective footing systems may not be included. The Standard should not be used to inhibit the development of such systems provided they comply with the design and performance considerations set out in Clauses 1.3 and 1.4.The application Clause merely outlines the procedures to be followed in using the Standard, but where conflict with AS 3600 arises with regard to footing system design and construction, the provisions of AS 2870 prevail.
