It's amazing to watch! There was a row of townhouses like that put up near my old house. They had a crane and a steady stream of trucks bringing in the modules.

It's amazing to watch! There was a row of townhouses like that put up near my old house. They had a crane and a steady stream of trucks bringing in the modules. Truck shows up, two guys put straps around the module and hook it to the crane. When I was watching, they were on the second storey, so there were two guys on the roof that helped the crane operator drop them in place. Take the straps off, throw them down to the ground, and repeat. Pretty incredible watching the entire storey of a block worth of townhouses being assembled in an afternoon.
