Abstract:
Today HBIM represents a new system for the management of Cultural Heritage, at every stage of its life cycle, from intervention to conservation. Developed on the basis of BIM, HBIM is, however, affected by some problems related above all to the initial phase of data modelling: it is difficult to model the uniqueness that is a characteristic element of cultural assets. The HESUTECH Research Laboratory has conducted different experiences in the field of HBIM, on very well-known cultural heritage, each one different from the other. The peculiarity of each asset and the aims of HBIM were the decisive elements in dealing with the choices of survey and modelling of the assets.
The Appartamento of Troia in Palazzo Ducale, the convent of S. Maria in Castiglione delle Stiviere and the basilica of San Marco in Venice, in fact, required very different approaches: the choice of which was based on a prior in-depth analysis of the needs and objectives to be achieved through HBIM. Various data acquisition tools (laser scanner, photogrammetry) were used, chosen on the basis of the goals and characteristics of the asset, such as the materials and construction techniques used.
The different objectives of HBIM, on the one hand the optimized management of all operations related to mosaics and on the other the programmed preservation, have led to radically different choices even in the phase of modelling the geometric data, favouring the modelling by surfaces or by parametric solids.
In this paper, several application cases are presented and the comparison between them, even before data acquisition and modelling, is made on the basis of the objectives identified for each case study.

Relevance for the conference: HBIM represents a new system for the management of Cultural Heritage, but they need to be designed specifically for each cultural asset in order to maintain its own uniqueness
Relevance for the session: The article addresses the sensitive issue of geometric data modelling for HBIM. This choice cannot ignore the characteristics of the asset itself and the objectives of the information system
Innovation: We cannot assume only one modelling approach for HBIM, as it happens for BIM. It is necessary to deal with characteristichs of the asset itself
