The first steel beam was put in place in the effort to rebuild 7 World Trade Center in New York. The 52-story building is scheduled to be completed by the end of 2005. Using lessons learned from problems identified in the Twin Towers, emergency exit stairwells will be twice as wide as required under the code so that people can exit going down while fire fighters have room to go up. In addition, in order to keep the stairwells clear of smoke, they will be pressurized.
