[FULL NANO FABRICATION] {Arc Fleet contains Nano constructor vessels which deploy containers full of nanite constructors. Released onto barren ground they mine the earth they are set upon and slowly grow a building into place as coordinated by their parent nano constructor vessel. Once construction is built, NanoVessels deactivate Nanites and populace is sent down via transport ships.} + Very Easy to implement given the technology + Relatively simple Construction inventory required - Can take a long time to construct a building. - Grey Goo Hazard
[PARTIAL / PHASED / HYBRID NANO FABRICATION CONSTRUCTION] {Similar to above, however, Arc features populated and unpopulated 'building cores' that aid and speed up the nano fabrication process as partial constructs, prefabs, and scaffolding.} + Faster than pure Nano Fabrication + Allows habitation of partially constructed buildings, ingress and egress during nanoconstruction may be an issue, - Potentially Costly - Grey Goo Hazard - Slightly more dangerous if buildings populated during construction though can be controlled provided nanite areas and target materials of operation are 'zoned' correctly. - requires higher sophistication of nanobots than previous technique.
