Valutazione BIM-based ex ante dei rifiuti da C&D per la demolizione selettiva

The paper outlines a methodology for the preliminary assessment of con- struction and demolition (C&D) waste. In particular, the work focuses on the possibility of implementing selective demolition procedures, aimed at the punctual “deconstruction” of the building in order to streamline the mate- rials and components reclamation operations, maximizing their reusability and/or recyclability potential. In this sense, the aim of the study is the elaboration of a BIM-based proto- col for the pre-determination of material flows from demolition, through the standardization of the C&D waste production process. The protocol is in line with the Italian legislation and designed in the framework of the selec- tive demolition site in compliance with the guiding criteria of the European legislation. The information derived from the application of the methodolo- gy fuels the knowledge system needed to frame the labelling of C&D prod- ucts towards their possible reuse or recycling. Starting from the analysis of a case study, identified in the former Corradini industrial complex, located in the eastern area of Naples, the research experimentally developed the methodological articulation of the protocol, aiming at the quantification and management of waste flows, their pre-characterization according to the CER code, and the planning of material flows towards reuse, recycling or landfill chains. The research is the result of the PROSIT project - “Designing in Sustaina- bility”, carried out by the Department of Architecture and the Department of Structures for Engineering and Architecture of the University of Naples “Federico II” with the public-private consortium STRESS scarl and in collab- oration with the Municipality of Naples.
