In my previous article, I explained that ISO 19650 is a common set of rules to help Revit users get rid of their "work fog" and that it's not a difficult theory, but rather a way of thinking that aligns the way information is handled. In this article, we're going to look at some common pain points that many Revit users share. The problem is, "I'm creating a model and drawings in Revit , but my boss and other stakeholders rarely look at the BIM model and only look at PDF drawings to check and give correction instructions."
There are many people who have been instructed by their boss to "fix this line" or "correct this dimension" and think, "If I make that change, it will affect other parts ...".
Creating a model in Revit isn't just about drawing 3D shapes. Floors, walls, equipment, etc. are connected with information, and if one is changed, the related parts will also be affected. But if you're just looking at PDF drawings, you can't see the connection. As a result, the intent of the correction is not fully shared, and rework and omissions are likely to occur.
So, is this simply a matter of "my boss doesn't understand BIM "? In fact, not quite. For a long time, the Japanese construction industry has relied primarily on paper and PDF drawings. As a result, the rules of the work itself, "how to check the model", are not well organized.
But there's a lot more to a Revit model than just drawings. For example, if you change the design of the position of the wall, you can only see that the position of the line representing the wall has changed. However, if you look at the model, you can see a lot of things like the interference with the space, the relationship with equipment, the impact on quantity, and so much more on unusual walls due to design changes.

In other words, the real value of Revit isn't just about creating pretty 3D models and drawings, it's about sharing the information you need. ISO 19650 believes that it is important to "make decisions accessible to the people who need it, using the information they need."
For example:
- Clash detection is performed against the Revit model using Forma's collaboration features.
- Dimension checking is determined by drawing in Revit while looking at the model
- Finish information is identified by the attributes included in the model.
In this way, it is necessary to decide in advance "who will use what, and how to check and judge information from the model" and ensure that it fulfills its role. "Your boss and stakeholders don't need to be able to use Revit perfectly." What is needed is not so much advanced modeling technology as it is sharing "what information to look at" with everyone. This means that even if your boss or stakeholders don't have the Revit software itself, they can use the cloud solution, Forma Data Management (formerly Autodesk Docs) is what you can do.
As this mindset spreads, the frustration felt by Revit users will gradually change. If you have a culture of looking at the model, it will be easier to share the intent of the modification and the background of the change, and you will be able to notice problems that you would not have noticed from the drawings alone.
Most importantly, this will enhance the quality of your Revit models. If only the drawing is needed, the information that is not written out in the drawing does not matter, even if it is incorrect. However, when the model is seen by all stakeholders, you need to have all the information contained in the model correctly. This is very important as an information asset that will lead to the future.
Revit isn't just a 3D drawing software, it's a tool to share information and make decisions together. And the Revit model that you've worked on really comes into play when people start using that information to make decisions. That's where the value of the idea of ISO 19650 comes in.
