So... that's a lot of labor, in high concentration. The majority of the real labor-of-construction would appear to be happening in factories elsewhere. To bend metals, to make the "parts", to get things staged to be shipped and off-docked on site. I wonder how it compares to "regular" on-site framing, build-out, and finishing?
