I am trying to follow the evolution of IFC for Infrastructures.
-First of all we have the information found in the BuildingSmart webpage (https://buildingsmart.org/wp-content/uploads/2017/07/08_bSI_OverallArchitecure_Guidelines_final.pdf)
Apart from that, there are other intitiatives like BRIM, for Bridge modelling https://www.fhwa.dot.gov/bridge/pubs/hif16010.pdf
Are all these Groups working together (coordinated) in different aspects of IFC for Infrastructures?
Which initiative should I follow if I want to be updated in the IFC for Infrastructures?
