Are you talking about the ones that look like military barracks? If so, we passed by and took some pictures just this past Saturday. They definitely stand out as something different. I just got back today but will try to post the two pictures I have of them. They were working on some larger units when we were there. I guess they would be about the size of a medium sized mess hall. We saw two of the bigger ones that they were working on. Still can't get a straight answer on what they're for though.
