“…Nevertheless, the Industry Foundation Classes (IFC), BIM' standard for interoperability, is not adapted to deal with the temporal dimension and uncertainty characterizing heritage information. Concerning the latter, as "recreating a lost building or building phase invariably means making hypotheses and suppositions" (Boeykens et al, 2018), multiple methods have been proposed for historical validation of the geometric models (Bianchini and Nicastro, 2018;Boeykens et al, 2018). Regarding the former, although execution phases in BIM software might be used to document different states of existence in BIM environment (León-Robles et al, 2019), the representation of different sequences considering various hypothesis related to different sources of information is not possible.…”
