Common Data Environment (CDE). An efficient and effective use in Italian standard UNI 11337:2017

The article seeks to define the rules for building and managing data sharing environments, such as structured connection sites of information atoms, in order for them to be fully correlated (Pavan, 2017a). With the diffusion of Building Information Modeling (BIM) in the information systems of the construction industry, it was necessary to create a specific digital data sharing environment. This environment was introduced by the British standard BS 1192-1: 2007 (BSI, 2007), under the name of Common Data Environment (CDE). In the first time, it was regarding the information collaboration rules in the AEC (Architectures, Engineering and Construction). Only in second time, in the PAS 1192-2: 2013 (BSI, 2013), it was extended its horizon, to information management during development phases of constructions processes, using BIM. Some interpretative difficulties contained in the above technical specification (PAS 1192-2) and the lack of knowledge of the instrument (CDE) by the public and private clients are now creating operational confusion which is likely to limit, if not in some cases, to erase, part of the innovation introduced by BIM systems in this sector. Starting with the simple confusion of the BIM-CDE with a traditional file hosting environment (and not data management environment), until the impossibility of statistical data processing or data relational verification and validation (Pavan, 2017b). This research defines the criticalities found in the non-rigorous application of the BIM-CDE and identifies possible prospects for system improvement. Future developments are aimed at creating specific analysis and processing applications for single data to increase the performance of chain-management.
