State of the what?

I go to school in a brand new, state-of-the-art law school building(CU's Wolf Law Building, it's supposed to be super cutting edge and all). This sign just appeared in the library ladies room:

"Sensitive Plumbing... [you know how it goes]"

We don't even have low-flow toilets. They are NEW, REGULAR, COMMERCIAL fixtures. Methinks someone cut corners on construction (the fact that roof tiles were falling off all last year is another key indicator. They are redoing the entire roof, just a year and a half into this puppy. Aren't buildings supposed to last longer than that?).
