Megaprojects in Trek

It takes a lot of resources to build a starship - but starships are not the biggest infrastruture in the Trek franchise. The trio look at the mega projects we see in the Star Trek future, from the shipbuilding facilities at Utopia Planetia to moving Deep Space Nine.

What does it take the move a starbase from planet to planet, like we see in "Star Trek: Picard"? What about terraforming efforts? All these future endeavours and more may be beyond today's techonogy, but what are the implications in this imaginary sci-fi universe?
