What comes first when implementing data templates? Refurbishment case study

Abstract

A built entity is composed of different construction products and its data digitalization is found to be crucial. However, this is a highly complex task due to stakeholders wide range of solutions and requirements. The ability to identify the most relevant Data Templates (DT) is key to set meaningful steps for the value-chain innovation. This work contribution is the development of a case study using a Portuguese social housing building representing the stock to be refurbished under EU Renovation Wave. Findings indicate that relevant construction and deconstruction activities address elements as windows, roofs and doors. When targeting deconstruction activities, hazardousness and waste analysis are crucial vectors for product digitalization. On the other hand, when targeting construction activities, key aspects to evaluate are the energy efficiency index and facility management. Products BIM dimensionality, detail and layers are crucial elements for both types of activities for DT cases implementation. (c) 2023 the Author(s).
