Construction product approval process
Construction Quality Planning Guide, Draft for Consultation, Published by the Construction Innovation Hub in May 2020, defines the Construction Product Approval Process (CPAP) as: ‘An adaptation of Production Part Approval Process (PPAP) that is aimed at those enterprises that will feed construction with new componentry for offsite builds.’
The Production Part Approval Process is: ‘A process, standardised by both the automotive and aerospace industries, that outlines the steps and requirements for approval of production designs and/or manufacturing processes throughout the product development cycle. It also ensures that the entire supply chain understands these steps when procuring externally manufactured parts.’
