They can build it using bots. Develop the bots in the deserts. If they can make them move about and assemble/repair things in a desert, they can handle moon dust. Granted it's at least a decade long project. But once we've got the bots with AI, they never get tired and can keep building. Alternately I guess we can slingshot stuff off the sun like the Parker Probe (0.06% speed of light, it's a start)
