Provisions in Australian Standards, that are referenced in the NCC, must be complied with, in as far as the NCC references that particular standard. And those guidelines say that a normative element is an element of the standard which describes the scope of the document or sets out provisions. Standards Australia is the nation's peak, non-government standards writing body and they draft Australian Standards to a very strict set of guidelines. Now, that's one question, but there's surely somebody wondering about another question, what on earth does this guy mean by informative or normative? Well, if that person's you, I'm about to help you out. Are these design life provisions, found in that standard, normative or informative? That is, of course, how long the retaining wall has to be designed to last. Still on retaining walls, what happens if you do AS 4678 for your retaining wall and you come to the design life requirements in that standard.
#BUILDING A RETAINING WALL MANUALS#
So, the answer is yes, you can still design retaining walls to the structural design manuals in Part 3.0, such as AS 1170. And in case that's not obvious, we've placed explanatory information in the new Part referencing AS 4678, that indicates that this is simply one option amongst others that can be used for determining the structural resistance for a retaining wall. This is acceptable construction practice, so it's a Deemed-to-Satisfy solution to use AS 1170 or any of the other manuals they aren't in 3.0. Part 3.0 Structural provisions points out that you can achieve that same Performance Requirement by following 3.02 to 3.05, which are about determining and resisting actions, and how you can use the 1170 series, for instance, to do this. Yes or no? Well, Performance Requirement P2.1.1 requires that buildings and structures be structurally stable and resist the actions that are reasonably applied to them.ģ.1.2.0, which we added last year, says that this is achieved if you design and then construct your retaining wall in accordance with AS 4678, the new acceptable construction manual.īut that's not the only way.
Since then, we've been asked if the old structural design manuals referenced in Part 3.0 can still be used. It was referenced for the first time to provide a Deemed-to-Satisfy solution for a range of earth-retaining structures.
#BUILDING A RETAINING WALL MANUAL#
We now have two questions to do with retaining walls.Ī new ACM or acceptable construction manual was introduced in NCC 2019, in Volume Two for earth-retaining structures.
