The preservation and the regeneration of the existing built heritage is still characterized, even in the context of an increasing digitization of the value and supply chain, by inefficient time and costs management, along the whole life cycle, as well as by discontinuity and lack of information on the one hand, by redundancy and duplication of data on the other. Accessibility, usability and feasibility in order to univocally implement information, also by real–time monitoring, are areas of growing interest to all actors of the building and construction value–chain, with particular reference built heritage knowl-edge phase, as well as for the stakeholders of complementary industries as ICT, for the development of integrated digital solutions for data acquisition, modeling and visualization.
