I was wondering if there are properties in the ifc file schema that can be used for logistic and phasing purposes (aka 4d bim). If you want your bim data to be used in a Building Smart environment the aspect ‘time’ is crucial for good visualization and scheduling. There is a wide variety of socalled ‘4d bim software’ available to !CONNECT! geometry databases to some sort of excel or other planning database. I cannot find documentation that this 4d aspect can be incorporated in as ifc definition to begin with. Any examples of doing 4d with ifc.
I think some variables in the form of ifctimeerected or ifctimemounted would be crucial for builders and would make it very a software independent and useful.
As fas as i can oversee the practice of today is that sadly a lot of ifc is exported and imported according to the phase. This the risk of having too many (offline) duplicate clumsy exports to maintain in folders somewhere. Not mentioning the file hussle and waist of time importing exporting communicating. Needs to stop.
