Interoperability for building process. Model and Method.

In this paper we intend to analyze the chances about the implementation of a Building Information Modeling (BIM) as a method in the construction process, investigating in particular the role that, in it, takes the concept of interoperability and how this can be developed according to the most appropriate approach case by case. Moreover, the aim is to define a critical examination of how the chances offered by new technologies are related closely with the management of the 3D model and its use for management purposes. BIM is an interactive and clear tool organization of building processes, functionally worth in order to perform at all times punctual and strict controls through the parametric virtual model of a building. To lead from idea to realization and to the management, the approach to the methods and processes of BIM are configured as appropriate for the business realities that aspire to qualify as organized structures of integrated design, ready to compare with an increasingly aggressive marketplace. If we consider the existing, to get benefits by BIM approaches oriented to manage the building, it becomes a strategic objective. Remarking the two main meanings of BIM as a model and as a method at the same time, we aim to study how it can be used in the management of the existing built and how the more established Anglo-Saxon procedures could be characterized the actions aimed to interventions in retrofit and functional requalification.
