Civil, Construction and Environmental Engineering 1,3,4{davide.simeone|ugomaria.coraglia|antonio.fioravanti}@uniroma1.it 2stefanocursi@hotmail.it In BIM processes, the concept of Common Data Environment - CDE - has often been depicted as a key element for successful collaboration and information sharing among different actors but, in current practice, acts as a mere documentation repository ineffective for true collaborative purposes. Therefore, the idea of CDE seems to be overrated on the one hand and unexploited on the other , while effective collaboration is still far from being decisively supported. To overcome this lack, the present research focuses on the definition of a new generation of CDEs, enhanced with an information level for knowledge integration provided by different information carriers such as models and datasets. The paper discusses its development through a graph database platform and dedicated methodologies for data retrieval and query, to verify coherence and consistency of information among different models.
