Design for Durability & Demonstrating Compliance to the Clause B2 – Durability of the Building Code
Over the years durability design guidance and standards have been published which assist designers with the material selection and durability design of common construction materials. For timber and concrete, and more recently structural steel, the Clause B2 – Durability of the NZ Building Code now covers the majority of materials used in structures in the New Zealand environment.
However, it appears that there are misunderstandings and confusion on how designers can demonstrate compliance with the Durability clause, which ranges from the selection of corrosion protection systems to ensuring its application within the built environment. This protection needs to be undertaken to the appropriate level of quality to meet the Building Code durability requirements.
This seminar will first highlight the requirements of the Clause B2 – Durability, followed by an overview of the steel durability technical specification SNZ TS 3404, durability of some other metals used in structural design, the durability part of the concrete and masonry standards and durability requirements for the timber standard NZS 3604. This includes a discussion on achieving the required durability during construction, based on the relevant standards, including the steel fabrication and erection standard AS/NZS 5131, the concrete construction standard NZS 3109, the masonry Standard NZS 4230 and associated timber standards and good practice.
Examples of acceptable solutions, as well as case studies of when things go wrong will be given together with remedies and good practice and the seminar will conclude with the current status of the relationship between Producer Statements and the B2 Clause, what to do in that situation and a possible pathway moving forward.
