If so, than indeed you will need call activity + a parallel gateway join.
You will also need to implement some kind of loop + condition check for your workflow 1 and 2 to see if they can be executed.

Yes, Workflow3 can only execute after both Workflow1 and Workflow2 are completed.

Could you point me to an example of the BPMN constructs used for the loop + check condition you are referencing?

Thank you again for your help.

Well, there is loop support in BPMN, but that is too complex for this.

I would simply do seomthing like this

Check condition workflow 1 —(ok)–> execute workflow 1 –> go to join
–(not ok) –> timer intermediate event –> go back to step 1

And the same for workflow 2.
