ER45 From lessons to practice: Compliance and assurance for manufactured buildings (June 2020)

This report investigates international practice in quality assurance and compliance for manufactured buildings and the enabling factors that make them work well.

Traditional assurance and compliance regimes in New Zealand appear to be insufficient for manufactured buildings. As New Zealand is increasingly exploring greater use of manufacturing in construction and other modernised construction methods, it is essential to learn from countries where manufactured buildings are a more significant part of their building industry.

By using a mixed method approach, including a literature review, interviews, a questionnaire survey and workshops, this project discussed the quality assurance methods used in Sweden, Switzerland, UK, Australia, Singapore and China and the implications for New Zealand.

A prototype model of QA and compliance, together with a set of recommendations were suggested for stakeholders across the supply chain to consider in order to reduce the regulatory consenting burdens and to improve the performance of manufactured building
