Nuclear detonations are very effective earth movers, perhaps capable tools in an Megascale structure project. See project plowshare. I'm not sure if the energy to make a weapon (enrichment primarily) is less than using conventional diggers and haulers. That is, are nuclear detonations efficient relative to other earth moving methods? Almost certainly.
