| Status/Comments: | BUILT. The world's
safest, most advanced building in its height range. Features
3-foot-thick reinforced concrete core walls, extra-wide stairwells, separate
emergency communications system. Ultra-clear glass made to look blue by
metallic reflectors lining bottoms of window frames. Tower
constructed in record time, unencumbered by political considerations
hampering progress on main WTC campus.
Originally built by Silverstein as northern trade center annex in 1987, 641-foot tower collapsed in early evening September 11, 2001, having suffered critical structural damage from falling Twin Towers across the street. In order to leave room for the re-extension of Greenwich Street through 16-acre "superblock," Silverstein rebuilt Seven using only about two-thirds of the available parcel, increasing height to 750 feet in order to make up for lost girth. Lower 10 floors house ConEdison substation supplying power to Lower Manhattan. |
