The Scheme provides an independent audit of a ready mixed concrete plant's own quality system.
Audits are carried out by the Plant Audit Committee of five or more registered engineers. Members include representatives from the Concrete New Zealand – Learned Society and Engineering New Zealand (ENZ).
The Committee is resourced to enable it to conduct reviews to a high and consistent standard throughout New Zealand.
Its operations are carried out under a quality assurance programme certified to ISO 9001 and audited by Bureau Veritas (New Zealand) Limited.
It is the overall policy and strategic requirement of Concrete NZ and its Readymix Sector Group that the concrete manufactured by the participating members of the Plant Audit Scheme meets the requirements of NZS 3104:2021 Specification for Concrete Production.
The Concrete NZ Plant Audit Scheme provides the framework to monitor the consistent production of the concrete manufactured by the participating members of the Plant Audit Scheme and helps achieve the Concrete NZ commitment to ensure that concrete manufactured by compliant ready mixed concrete plants satisfies project and statutory requirements.
Concrete NZ is committed to continually improve the effectiveness of the quality management system for the Plant Audit Scheme and thereby maintain its reputation for achieving consistent quality.
