You are certainly right. The safety factor should have been extremely higher. You're talking about driving over a bridge as opposed to patronizing an establishment for hours and paying a fee to do so.
I don't understand the safety factor as far as what it entails to meet a specific number rating, but the upper deck at the stadium rested on the back wall and columns for 85 years. The renovation added more leverage in the form of extra rows, balanced it at its fulcrum, and held it in place with cables at the back end. A designed rise of a quarter inch may give it some room for error, but how did they know that the front half wouldn't crack and crumble when it is loaded with spectators? The first year following the renovation the Yankees held Bat Day. About 30 or 40 thousand bats were handed out, and slammed on the deck in unison. I heard that the upper deck was like being on a ship in high seas.
I was in the upper deck a few times when it began to sway a little, and I knew that it was safe, but I still felt somewhat uneasy. That deck has been frozen, thawed, baked and jumped up and down on every year for 85 years. How stable could it be?
