This practice design guideline provides a framework for independent third party review of structural designs submitted for building consent. The target audience of this document is professional engineers who are involved in the practice of structural engineering design and design review. It is not intended to be prescriptive, or to be used by others as a basis for prescribing the required scope for structural design reviews. However, it will provide useful background material to others including clients, regulators and building officials. It is hoped that this Guideline will lead to a simpler, safer, more reliable and more consistent approach being taken by structural engineering designers and design reviewers across New Zealand.
