Gio's station gets slowly bigger when you advance in contracts, the outter left part of his station will be available at contract #90 so you can build the Building Site

If i understand you correct, you want to use the available gold to gain XP? If that's correct, you can better buy Fountains, they give more XP per gold than the Building Site

If that's not going fast enough for you, and you have Antoni available, you can ship your gold to him and buy the El Drac, that has the same XP per gold as Gio's Fountain
