All 3 disciplinary models are exported to IFC. Woohoo 😂🎉
Now let’s combine them into a single multidisciplinary (federated) model,

The Federated model will be our base for BIM coordination. To illustrate better how to do it, I will use Solibri and show you an example.

In Solibri, in the main menu, click on File – > Open Model and select the model we want to load. For explanation purposes, I will open the IFC file of the Architecture model first.

After loading the file, we must set the appropriate model category. In our case, we set it to Architectural.

We add more models to the architecture by going to File -> Add models. We can select several models at once. Then you must correctly determine the model category.

After adding models, we choose the proper discipline category (see picture below). It will help us classify the clashes when we set up checking rules. You will dig deeper into it a bit later. No worries.
