Richard Tomasetti

Following the World Trade Center collapses, a decision is made to quickly transport the remaining structural steel to scrap yards, to be shipped abroad and melted down for reuse. Consequently, virtually all of it is disposed of before investigators trying to assess why the WTC collapsed can examine it. Michael Burton and other officials at the Department of Design and Construction—the New York City agency overseeing the cleanup operation (see (September 11, 2001-May 2002))—are responsible for making this decision. Burton clears it with Richard Tomasetti of Thornton-Tomasetti Engineers, the prime consultant on the cleanup job. However, referring to the subsequent WTC investigation by the National Institute of Standards and Technology (see August 21, 2002), Tomasetti will later admit that had he known the direction that investigations into the collapses would take, he would have taken a different stand. [Langewiesche, 2002, pp. 30; Glanz and Lipton, 2004, pp. 330 and 396] Authors and New York Times reporters James Glanz and Eric Lipton write that Michael Burton, “who had become the effective czar for the cleanup job, had made it clear that he cared very little about engineering subtleties like the question of why the towers first stood, then collapsed on September 11. ‘We know why they fell,’ he said. ‘Because they flew two planes into the towers.’ But he was deeply immersed in the details of hauling steel out of the debris pile.” [Glanz and Lipton, 2004, pp. 299] Much of the WTC steel will be shipped to India, China, and other Asian countries for recycling (see September 12-October 2001).
