Cross Information Improvement for an H-BIM Common Data Environment

In the construction community, the BIM approach to design, nowadays, is well-known even if still not completely spread out. Nevertheless, every design team using BIM often seems to act in its own way. In addition, the practical experience of the Con.Si.Lab. research team, when involved in design projects, is a huge lack of infor-mation flow through different design disciplines. This issue has been evaluated as a sensible obstacle towards quality especially in H-BIM projects, where construction site problems could create loss in time and money. The research had therefore the aim to create an original standard information flow, able to structure designers’ relationship starting from an information collection responsibility award given them by the BIM coordinator at the early beginning of design activities, using some dedicated synopsis tables. The team’s research method had an empiric approach through many years of experience in Historical Building construction sites design and management using BIM (i.e. H-CoSIM, Historical Construction Site Information Modelling). The case histories collection enabled the definition of the presented information flow, based up on an er-gotechnic parameters list gradually implemented and tested in many different sites. These parameters objects tables have been recently presented at the Italian Standard Body (UNI) in order to be enforced in a new release of the Italian standard UNI 11337, that provides two type of CoSIM: one at the design stage and one at the execution stage.
