The Project BIM Guide, Common Data Environment standards, BIM Modelling Standards and CAD/Drawing Standards can sometimes cover similar subject areas.
While areas of overlap or conflict should be identified in the Project BIM Brief, it is possible for inconsistencies between the documents to come to light during the project. In these instances the BIM Manager shall be notified immediately. In response, the BIM Manager shall determine, in consultation with the BIM Team (if necessary), which document will take precedence or whether amendments are required and advise the whole BIM Team of the ruling.
