AN INFORMATIVE TOOL FOR THE PRESERVATION OF THE WOODEN ENCIRCLING TIE ROD OF THE DOME OF SANTA MARIA DEL FIORE, IN FLORENCE

Proceeding under the assumption that restorers need to become more involved in the definition of the most advanced management tools for historic buildings, this paper aims to offer a contribution to the “informative” feature of the H-BIM methodology. Indeed, over the past few years, the issues addressed by scholars mostly concerned surveying and modelling techniques, whereas the organization of external data within the virtual model has rarely been considered. The necessity of defining a new operative tool for the maintenance of the wooden chain encircling the dome of Santa Maria del Fiore represented an occasion to develop an informative model that attempts to confer centrality to the knowledge process as a whole. Attention was thus focused on the articulation of the informative apparatus to be associated to the 3D model, as well as to its practical implications in terms of conservation
