They could leave half the building incomplete (open) and bring the track in through that opening. The current open area is close to the maintenance area, roadway, etc. - so maybe they just leave that open for a while? If it is an RMC, they do know how to thread the needle with their track construction so they have that experience going for them.
I find it interesting they do not have a large number of bolts/footers in the concrete slab, so maybe the track system will be somewhat self supporting (kind of like a traveling coaster) or they could end up using a Hilti type system to attach the supports to the building foundation? It will be fun to watch this go up this year.
So with that one side of the building going up, do you think they go ahead and remove the shipping crate wall and project the pumpkins on the side of the building?
