<P> In August 2010, Condé Nast, a long - time Durst tenant, confirmed a tentative deal to move into One World Trade Center, and finalized the deal on May 26, 2011 . The contract negotiated between the Port Authority and the Durst Organization specifies that the Durst Organization will receive a $15 million fee, and a percentage of "base building changes that result in net economic benefit to the project". The specifics of the signed contract give Durst 75 percent of savings up to $24 million, stepping down to 50, 25, and 15 percent as savings increase . Since Durst joined the project, significant changes have been made to the building, including the 185 foot base of the tower, the spire, and the plaza to the west of the building, facing the Hudson River . The Port Authority has approved all the revisions . </P> <P> A WoodSearch Films short - subject documentary entitled How does it feel to work on One World Trade Center? was uploaded to YouTube on August 31, 2010 . It depicted construction workers who were satisfied with the working conditions at the construction site . However, further analysis of the work site showed that dozens of construction - related injuries had occurred at the site during the construction of One World Trade Center, including 34 not reported to the U.S. Occupational Safety and Health Administration . Workers also left post-9 / 11 - related graffiti at the site, which are supposed to symbolize rebirth and resilience . </P>
