Specifies minimum requirements for the design, calculation and testing of piled foundations for civil engineering and building structures, on land and immediate inshore locations.

This Standard sets out minimum requirements for the design, construction and testing of piled footings for civil engineering and building structures on land or immediate inshore locations. It does not extend to offshore (deepwater) construction, or to detached Class 1 building as defined in the Building Code of Australia.NOTES:1 AUSTROADS Bridge Design Code should be considered for the design of footings for road bridges.2 The date of application of the Standard on a mandatory basis is matter for the relevant authority. AS 2159-1978 will be withdrawn following substantial regulatory implementation of this edition, or within two years of publication of this edition, whichever is the earlier.
