There are many competing standards worldwide for BIM and EDM tools, though ISO standards are essentially replacing these, which the entire world will eventually adopt. These include ISO 9001, which calls for document control. In other words, ISO 9001 tries to ensure that the right people have access to documents when needed, that those documents are up-to-date, and that no unauthorized users can access or change a document's contents. This ultimately helps ensure that essential engineering documents are up-to-date, comprehensive, and trustworthy, increasing compliance and improving operational efficiency over time.
