When it was finished, the world would know that New York had rebuilt.If reconstruction ever meant anything, it was during that raw period when the city still smelled like fire.Any sentiment seemed justified; you were lucky to feel anything at all. Steely resolve wouldn’t have built a successful tower, either.
It was a rubble of emotion that led to all sorts of expression that only seem embarrassing in retrospect: Freedom fries, commemorative coins, and eagles with tears in their eyes. Every dot on the city skyline is a product of its time, and if the 2000s were a painful, surreal, ultimately terrible decade, then so be it.But remember that the Empire State Building, Chrysler Building, and Rockefeller Center were built during the Great Depression, and while they certainly speak to their era’s ugly stratification of wealth, the towers also each managed to say something new and grow with the city around them.Today, you can stand in Washington Square Park on a clear evening, look north toward the Empire State Building, and see New York as it was and will be.

One World Trade Center was bound to be a fraught building, but at some point—presumably amid another round of designs mediated by politicians, the families of survivors, and the real estate developers investing in the project—it clearly just gave up on making any comment whatsoever.The highly reflective glass covering most of the tower seems to say, fine, whatever, see whatever you want in this facade. This failure is most obvious in the spire, which stretches the building’s height to 1,776 feet.It’s the sort of empty symbolism that, like the Freedom Tower name, might have once seemed meaningful but now reveals itself to say nothing at all. Worse, actually, for the attempt to evoke American independence is actually an excuse to make One World Trade Center the tallest building in the United States, which will help sell tickets to the observation deck, a crucial source of revenue.The mistake is glaring because, to reach that symbolic mark, the 408-foot spire is much taller than it ought to be, comprising nearly a quarter of the building’s height.Its disproportion stretches out the top of the tower like an upside-down awl or medieval spear or extremely thin-ribbed condom. An earlier plan would have encased the antenna in a spiraling fiberglass radome, but it was scrapped due to budget constraints, exposing a sparely designed crown that almost looks unfinished.
(It was enough to be counted as part of the building’s height, a decision that appealed to sentiment more than logic.) The look is particularly unflattering at night, lit up in one color or another, especially compared to other spires along the skyline.Even the Bank of America Tower looks interesting by contrast.It’s the spire that most strongly suggests One World Trade Center is stuck in its peculiar moment of creation, when the number 1,776 might have seemed comforting, not juvenile.

For structural engineers like me, that meant figuring out what happened, and doing extensive research on how to improve buildings’ ability to withstand a terrorist attack.

Until those attacks, most buildings had been built with defenses against total collapse, but progressive collapse was poorly understood, and rarely seen.Since 2001, we now understand progressive collapse is a key threat.And we’ve identified two major ways to reduce its likelihood of happening and its severity if it does: improving structural design to better resist explosions and strengthening construction materials themselves.
