IT doesn't seem unreasonable to plan a project in stages, focusing on the most critical components in order, and only starting on the next once the first is ready. For instance with an airport you could build one terminal at a time. Obviously this would have limitations, but it could be a better system than trying to build a gigantic airport all at once, when it's already somewhat modular (i.e. terminals)
