The new construction products regulation: Opportunity or barrier for reused constructional steel?

This paper discusses the implication of the new provisions of the proposed Construction Products Regulation on the constructional steel reuse. The regulation extends its scope to products either previously placed on the EU market or installed in the EU, but at the same time provides guidance how to treat used, remanufactured or surplus products and a possibility to derogate from the full Declaration of Performance rules for products that have been previously assessed. The requirements include stable material properties, safety, durability and exclusion of overloaded components assessed by de-installer or pre-deconstruction auditor. The technical guidance and protocols for structural steel reuse are developed as Annex to EN 1090-2 in the CEN/TC 135. In our study, we provide an example of such process applied on the components recovered from a single-storey industrial hall that are offered for reuse in another building project.
