Construction Strategies to Avoid Progressive Collapse
    
  The Skyline Plaza Apartments in Fairfax County, Va after a 1973 progressive collapse that occured during construction of the 24th floor. The collapse involved the full height of the tower, and falling debris also caused the horizontal progressive collapse of an entire parking garage under construction adjacent to the tower. Fourteen workers were killed, 34 workers were injured.
