Abstract
HBIM modeling presupposes a series of methodological and content questions depending on the type of historic building being investigated. A particular case refers to a multitude of buildings, isolated or aggregated, that sprinkle our territory that do not stand out for their valuable architectural characteristics abandoned for different reasons and turned to ruins. This building category retains a valuable judgment when the typological constructive characteristics are recognized as explanations of “making architecture”, strongly linked to a place and to a time and that are worth preserving. The study of a ruin as a building typology involves various issues starting from the survey, both in terms of structure stability and room accessibility, and in terms of survey techniques to be used to acquire geometries that have lost their original conformation. The loss and deformation of the shape are therefore the main obstacles in the reconstruction of the historical evolutionary phases, fundamental for the definition of a recovery project that respects the nature of the building, now in a state of instability. Informed digital models, soon mandatory by law in most building processes, applied to the ruins thus become not only a means of documenting, cataloging, and communicating the built heritage but, above all, a tool that serves the project.
Highlights
Our territory is littered with buildings in a state of ruin
A significant part of the building heritage in a state of ruin is the one deriving from gradual abandonment resulting from social and cultural transformations rather than natural disasters
The transition between the last design stage and the current state of ruin collects all those events of decay, instability, and loss that characterize the building as we see it today
Summary
Our territory is littered with buildings in a state of ruin. Buildings that do not have a specific and recognizable archaeological value, that do not have a 'noble history' or a high typological dignity but which, in any case, the community recognizes as an integral part of the built heritage. A significant part of the building heritage in a state of ruin is the one deriving from gradual abandonment resulting from social and cultural transformations rather than natural disasters. "In this sense, the very start of the transformation process into ruin underlies a natural event or a socio-cultural motivation that has determined its exit from the dimension of material utility and the confluence towards a spiritual utility, linked to the recovery of aesthetic value and the documented meaning of the construction material" [1] "In this sense, the very start of the transformation process into ruin underlies a natural event or a socio-cultural motivation that has determined its exit from the dimension of material utility and the confluence towards a spiritual utility, linked to the recovery of aesthetic value and the documented meaning of the construction material" [1] (p. 109) (Figure 1)
