The aims of the paper is to underline, by focusing some aspects of the rehabilitation design work done on the real historic building in Tuscany, how the interoperability of BIM models may be an handy electronic collaboration, on real time usable by the different project participants and design team members, at any time of project and construction, from the first bids to the maintenance phases. However, implementing the BIM operability for the restoration design of CASA 21, the authors experienced problems on sharing the ongoing design information, like not complete compatibility of different software or updating data in real time, among the different members. The paper shows and underlines some of these gaps, stressing that functions and benefits offered by BIM models procedure need still better definition in term of capabilities and adaptabilities, not only due to software compatibility, but even due to the need of the implementation of an effective cloud-based collaboration platform.
