Executive Summary

Concrete Plant Audit Scheme

Your Stamp of excellence

The Scheme provides an independent audit of a ready-mix 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 New Zealand Concrete Society and IPENZ.

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 Quality International.
