And, I don't see the Neomorph creating any infrastructure because it's essentially designed to destroy the surviving life, then presumably itself is unsustainable so it then goes extinct, rendering the planet completely lifeless and then ready for restart.
As The RPG confirmed. And I personally see LV-223 as a barren wasteland to the point every facility is destroyed, covered and rendered inert beneath the storm.
