Have you looked into the size of a single lightyear? You either have to have a near infinite number of constructors, or near infinite speed. Along with the fact that he'd probably have to destroy a multitude of universes to gather the resources. We throw big numbers around so often in the rp, we never think about what they really mean.

The total size of the city in miles compared to the number of drones he had, each of which move very, very quickly. He had way more than one to cover each square mile of space, and each built a respective area. The resources come from a long amount of time spent mining uninhabited planets and stockpiling for a big project, and the city was that project. Yes, I believe that it was entirely feasible.
