Lucas Oil Stadium fully assembled in my Lego room in May 2009. Isn't much room to move around, is there?
Red Technic beams support the transverse roof trusses on the open side of the stadium during transport and storage.
The non-movable roof panels at the north and south ends of the stadium are removed. They simply rest on plates extending from the facade on one side (see photo of facade below) and on the edge of a transverse truss on the other. By the third day of BrickWorld 2009, they were starting to sag, so I'm going to add a beam underneath to stiffen them.
The south facade is removed by first removing two 2x2 tiles and two 1x2 panels from the sidewalk and one 1x2 tile from the roof line. Then the pins holding the facade to the adjoining wall are gently pried apart. The north facade is removed the same way.
Here's an image of the south facade. Red Technic beams brace the facade for transport. The black string seen running parallel to the beam is permanent. It compresses the wall, keeping it together. These arrangements have saved my butt on at least three occasions.
The center spans of the transverse trusses are removed next. At the end of each span two 1x8 tiles are removed and two pins are popped apart. The trusses are the only parts connecting the two halves of the building. The north and south bleachers, as well as the playing field, do not connect to anything.
The major sections are slid apart so they rest on their own tables. The four clamps holding the tables together are removed and the three 2x6 baseplate tables can now be separated. Braces have been added at table level to keep things from sliding during transport. I didn't use these braces after BrickWorld 2009, and I heard one of the bleachers tumble over while driving through northern Indiana (INDOT was resurfacing I-65). I haven't yet looked into the damage. Maybe you'll peek at it with me in Part II of the transportation saga...
Thanks, and yes, if you're building something large that you plan to display, you have to consider how you'll transport it before you start building!
Ironically, since I now have a large trailer, I'm planning to assemble it PERMANENTLY.
I've always thought this to be one of the best Lego stadiums there is. I'm currently working on a model of Citi Field, on a similar scale (although maybe not the entire stadium) and I'm making it de-constructible, similar to how you did.
