HBIM represents a very promising tool for the management of Cultural Heritage, both for daily operations and for the planned preservation of the asset itself. However, they require a specific effort to adapt tried and tested tools and methods for new construction to existing Cultural Heritage buildings. First of all, it changes the starting point of the process (new construction projects, surveys for existing buildings) and consequently the requirements for geometric and informative modelling change.
Especially in the field of Cultural Heritage, an in-depth and reasoned design of such a model (geometric and informative) is necessary to respond well to the needs identified in the processes of planned conservation. To this end, an appropriate semantic classification of the building elements must be carried out prior to modelling, taking into account both documentation and geometric description requirements.
The aim here is to propose a system for managing the information component of the model that takes its cue from the internal logic of BIM Authoring (Autodesk Revit) software and takes into account the operating practices of operators in the conservation sector. In particular, a system is proposed which no longer takes into account the traditional two-dimensional classification of elements, but which directly affects three-dimensional technological elements.
This is the case of the remains of the convent of S. Maria, near Lake Garda, where the geometric modeling was structured according to this new model of management of information content. In this way it was possible to give a complete description of the reality of the building (and its surroundings) without making it more usable and more readable by the operators.

Relevance for the conference: HBIM approach seems to be very promising for the management of CH
Relevance for the session: In a HBIM approach, we need to think to new systems of semantic classification to be applied to CH
Innovation: The new classification system takes into account the needs of the planned conservation together with the characteristics of the software itself
