Ground Zero will be rebuilt with oversight from an apparently tenuous partnership between architect Daniel Libeskind and developer Larry Silverstein. Still, for New York officials, any partnership is better than the uncertainty that has been dogging the project. “The agreement… came during an eight-hour negotiating session that stretched from Tuesday afternoon into Wednesday morning… The impasse centered on how much influence Mr. Libeskind would have on the design of the first office building to go up at the site, the 1,776-foot tower that will define the rebuilt trade center’s presence on the Lower Manhattan skyline.”
