Interesting to see them working so much on the walls with no visible work on the actual track or supports. Traditionally, for indoor coasters, the track work is (essentially) completed before any building framework goes up... here are just a few recent examples proving my point...

Makes me wonder why the change for this one... Are they just building the walls first on the park/parking lot sides to hide the track layout/construction from prying eyes? Is the actual track delayed from the manufacturer and they are just doing what they can to limit delays? Or is it possible that the side of the building facing the park will have some elaborate themeing (possibly rock work?) which will take longer to complete, thus why they are constructing these walls first? I'm not sure...
