Gantt chart as a project plan for the ISO 27001 project

We're trying to build a Gantt chart as a project plan for the ISO27001 project, and we're looking to see if you have any of the steps documented beyond filling the docs themselves.   e.g., folders 04, and 05 will require training users, missing controls under folder 14 will need to be built, tested, and deployed, such as enforcing BitLocker.   Folder 13 seems to address some of this based on mitigating risk from the risk assessment. Still, we're hoping this is already in a project doc with the assumption we have 0% complete, and we can pull out what's unnecessary or already implemented.
