9/11 WTC Towers Condemned Before 9/11, Cost to Dismantle $2B+, 2007 Deadline, Known to Rudy Giuliani (Mayor of NYC from 1994 – December 2001)
21 July 2018
Mr. President,
As early as 1989, it was known to the owners of WTC that the buildings must be brought down before 2007 because the interior steel and exterior aluminum were both compromised and the buildings would be at risk of collapsing — the cost to dismantle them was estimated to be $2B (or more) in 2010 dollars, inclusive of asbestos remediation.
