“That’s mainly because of the water in a toilet bowl. “The standards for tolerance are tighter in a residential building than in an office building,” says von Klemperer. The sort of slender, reedlike condo building designed for the few, the foreign, and the filthy rich has to work that much harder to stand firm, like a ballerina remaining en pointe in a gale.

THE DOWNSIDE LIFE SUPERTALL TOWER CREAKS FULLĮven a bulky office tower planted on a full city block - like, say, the John Hancock Tower in Chicago - can creak and shift on a blustery night. “You don’t have repeatable results because the shape of the building changes the performance.”Īll skyscrapers face a common foe: wind. “Once you get over 40 stories, every one of these towers is a prototype,” Edgett says. It’s also true that the architecture of tall buildings is an evolving field. Developers are widely unfamiliar with the concept of mistakes, architects don’t want to talk about what can’t or shouldn’t be done, and few high-rise engineers want to talk themselves out of the next big job. As long as problems don’t crop up before they unload the property, they can do whatever they want.”Ĭonsensus on these issues, at least the on-the-record kind, is hard to come by. The people who put up the buildings are not accountable for their quality. The problem is not confined to tall buildings, says a well-known structural engineer who asked to remain anonymous so his career wouldn’t spontaneously combust: “It’s the way development operates in New York. It’s the fulfillment of the kind of scary situation you’re warned about.”Ībsolutely, says Steven Edgett, an elevator specialist and the president of the California-based Edgett Williams Consulting Group: “As soon as I saw the core of 432 Park, alarm bells went off.” The elevator shafts are too tight, he says, making breakdowns a foregone conclusion. Not at all, says James von Klemperer, president of the architecture firm Kohn Pedersen Fox, which plants skyscrapers all over the world: “In a building that thin, this kind of thing can happen, but it shouldn’t.
