I wish I could vote you up more than once. If they are taking advantage of economies of scale they should be able to obtain for higher quality materials (and in looking over their materials this is not stuff they are buying at Home Depot). Couple that with the advantages of building all this stuff indoors, sheltered from the weather while under construction and that they can afford to create specialized jigs and tooling to not only speed the construction time but also produce far more consistent and higher quality results they should be able to do things that you simply can't do on site in the field.

Transportation of prefabbed housing has always been the major issue, which is why they spend so much time talking about how they are solving that :)
