A bitta bologna on the sandwich

Follies are often known for their central piece - whimsical centers with fun and perhaps some, albeit little, function. At the center of the sandwich aka courtyard rests a comfortable 6 inch slice of pink insulation. These fine fellas rode in from the coast to install it across a ~80x~200 foot section. Beneath this is a ~1' steel reinforced concrete footer atop approx 6 inches of gravel. Which I've heard rumor lays atop another 10' or so above two stories of vivarium stuff (houses for research critters). This sandwich requires structural steel (think toast) because of the plans to create another medical building atop the structure in a few years. Above the bologna is a layer of something we'll come up with a name for later...
