UPDATED TIMBER STRUCTURES STANDARD

06 Dec 2022

Standards New Zealand have recently confirmed that the Timber Structures Standard NZS 3603:1993 has been superseded by NZS AS 1720.1:2022 Timber Structures Part 1: Design methods. This newly published standard supports the use of timber as a renewable and carbon-negative resource that can lead the way for the development of more innovative, sustainable and robust structures across New Zealand.

NZS AS 1720.1:2022 sets out general requirements for the verification of timber structures and a wide range of engineered wood products including laminated veneer lumber (LVL). The revision allows designers and engineers ways of designing timber structures that are outside of the scope of NZS 3604:2011. For fire resistance, NZS AS 1720.1 refers to AS/NZS 1720.4 (2019) Timber Structures – fire resistance of timber elements.

NZS 3603:1993 Timber Structures Standard is still citied within B1/VM1 subject to modifications for the design of timber structures and B1/VM4 as an option in relation to timber piles.  The use of NZS AS 1720.1:2022 Timber Structures Part 1: Design methods would need to be presented as an alternative solution if a designer wanted to adopt the new standard in support of their design.
