Exhaust vent design element
At first glance I assumed that a Dalek was hiding or trapped behind this simple wooden fence assembly (remember their biggest downfall was that they couldn't climb stairs) but upon further inspection it became evident that this particular structure was an exhaust vent for some mechanical unit.
The word of the day for this particular example is going to be 'coordination'. I don't particularly know how one could miss a structure of this size in the middle of the plaza (even during CD phase) and I sure can't figure out when the engineer who placed it here lost all sense of aesthetic sensibility or which contractor shrugged his shoulders and said "Sure, whatever." during construction but someone should have noticed this, asked about it and resolved the issue.
I will update with a zip code when I figure out where this is.
