Allied Concrete’s Penrose and Nelson plants secured the inaugural Gold status at the 2019 Concrete New Zealand (NZ) Plant Audit Scheme awards presented at the Concrete NZ Conference in Dunedin 10-12 October.

With the 2019 dissolution of the New Zealand Ready Mixed Concrete Association (NZRMCA) as part of the Concrete NZ launch, the Plant Audit Scheme moved under the new association's banner.

In doing so, the Scheme, which provides an independent audit of 188 ready mixed concrete plant’s quality systems in line with NZS 3104 Specification for concrete production, assured its future as part of the wider construction sector.

Previously, the Plant Audit Scheme Committee had awarded an annual Supreme Plant Award. However, under the Concrete NZ branded Scheme a new Gold, Silver and Bronze acknowledgement system has been introduced as a simpler, more transparent way of rewarding continued excellence.

To receive an annual ‘Excellence’ certificate a plant must not have received any ‘determinations’ (i.e. corrective actions) or have its Test Frequency Requirements questioned under the Scheme.

In short, this means that plants that have demonstrated three years of continuous ‘Excellence’ are now recognised as Bronze, those with five years of continuous ‘Excellence’ as Silver and those with 10 years of continuous ‘Excellence’ as Gold.
