To the person that moderated my post offtopic, RTFA and make the connection.
To save time and money, management made a disastrous decision. But in the case of the current article, it was narrowly avoided. The title is misleading. It wasn't a design flaw from the architect, but a stupid decision to save money on the implementation. (Which also is the reason why the Gulf spill happened.)

"But welded joints, which are
labor-intensive and therefore expensive, can be needlessly
strong; in most cases, bolted joints are more practical and
equally safe. That was the position taken at the May meeting
by a man from U.S. Steel, a potential bidder on the contract
to erect the Pittsburgh towers. If welded joints were a
condition, the project might be too expensive and his firm
might not want to take it on"
LeMessurier put in a call to his office in New York. "I spoke to Stanley Goldstein and said, 'Tell me
about your success with those welded joints in Citicorp.' And Stanley said, 'Oh, didn't you know? They were changed--
they were never welded at all, because Bethlehem Steel came to us and said they didn't think we needed to do it.'
