Open the project concerned, scroll to the bottom of the page, then click “Archiver le projet” (archive project) or “Supprimer le projet” (delete project).

Archiving
An archived project can no longer be edited. You will find your archived projects here: https://workspace.airplan.be/v2/projects/archived
To edit it again, open it and click “Désarchiver le projet” (unarchive project).
Deleting
Deletion is permanent: Airplan asks you to enter a number shown on screen to confirm it. Deleted projects cannot be recovered.
💡 Need to start again from an existing project? “Dupliquer le projet” (duplicate project), in the same place, creates a copy.
What about feasibility studies?
A study cannot be archived. You can delete it (“Supprimer l’étude”, delete study) or convert it into a project (“Convertir en projet”, convert to project).
