These great projects will astonish the rest of the world. But they are quite expensive. You can change the expenditures each winter in the budget and so influence the duration of the completion. It is not possible to work on more than one project simultaneously. A project begin is seen as a solved task, so other tasks are possible in this quarter, but no reforms or budget changes.

Consider carefully whether the state is really capable of paying the project! The completion can take more time than estimated, but in any case it will be completed.
