Today it takes about seven years to build something that size on Earth but directing all of the solar systems resources in a emergency situation building it quickly is not impossible. The problem building it on Earth is gravity supporting those massive superconducting magnet in the nacelles require a massive structure. You would have to go straight down to bed rock to have a solid structure for the ship yard. Having that pit being the future home of the ship yard makes sense.
