Realtà Aumentata con GIS e BIM a servizio dei processi di scelta complessa / Augmented Reality with GIS and BIM at the service of complex choice processes

The paper illustrates, for complex choice processes, a methodological framework for satisfying a typically public need for a new work or a new service. Leaving traditional models of choice, based on a set of information of various kinds, often not always clear and/or available to the user, the research proposes the use of an advanced toolkit that allows to choose ‘consciously’, enjoying at the same time a series of contents that can form a digital model of the city.Starting from a short introduction on digitization theme of the construction sector, the paper explo-res the possibility of organizing information of various kinds within specifically designed digital models, for an effective and non-redundant management of available data. Specific insights follow on the tools that the model proposes to integrate (BIM, GIS, AR). The study concludes with the possible applica-tions in the field of public policies, particularly in cases of complex choice of intervention alternatives (location, functional, technological etc.)
