Revit Outsourcing & Overflow Support
BIM and Revit are not the same thing
Revit is software. BIM is a way of managing project information. A Revit model can support BIM work; opening Revit does not create it automatically.

The words “Revit” and “BIM” are often used as if they were interchangeable. They are not. Revit is Autodesk’s building-design authoring software. Its native project file is .RVT. BIM — building information modelling — is a way of producing, managing and exchanging information about a built asset. Other authoring tools exist. A project can use Revit without meeting a particular BIM information standard. A BIM process can use software that is not Revit.
Where ISO 19650 fits
ISO 19650 is the international series used when appointments talk about managing BIM information over the life of a project or asset. Part 1 (2018) is the published starting point for those ideas. It is about how information is named, shared and controlled among the organisations involved. It is not a description of Revit, and it is not satisfied merely by issuing a .RVT file. Older UK documents used numbered “BIM levels” (including “BIM Level 2” under PAS 1192). That vocabulary should not be attached to a drawing-to-model conversion unless the appointment actually requires those information-management duties.
What CAD to Revit conversion is — and is not
Converting CAD or PDF drawings into a native Revit model gives the practice editable architectural geometry in the agreed Revit version. That can be a useful input to later BIM workflows: coordination, drawing production, or IFC export if specified. It does not, by itself, deliver clash detection, COBie, a digital twin, asset information for facilities management, or ISO 19650 compliance. Those require their own scope, standards and often different specialists.
Questions
Not in the standards sense. Whether a file meets a BIM information requirement depends on what the appointment asked for — not the file extension.
