The Unremarkable Building of Solarana

Solarana's building operates without incident for a few years. But on April 23, 2013, workers heard this loud sound. And a bunch of cracks that appeared in support columns. Everyone was immediately evacuated from the building and sent home for the day. That evening, an engineer inspects the building. He takes one look at the columns. He's like, I'm getting the fuck out of here. So you know what, good. Building's an imminent danger of collapse.
