World Trade Center Disaster
The tragic events of September 11, 2001 will be forever etched in history, and have had an immeasurable impact on the lives of the individuals and families that were directly affected.
In New York City, emergency response teams, including hundreds of police officers and firefighters, were immediately dispatched to the World Trade Center site by the Mayor's Office of Emergency Management. Simultaneously, the New York City Department of Design and Construction retained four major construction management firms to assist in the search and rescue operation, as well as LZA Technology, which was charged with responsibility for all structural engineering operations at the site.
The structural engineer played a crucial role in enabling the intense search and rescue effort to proceed without hindrance on a 24-hour basis, while maintaining safety in an environment fraught with the risk and danger posed by partially collapsed and severely damaged structures.
Services provided by LZA Technology included immediate damage assessment of buildings in the collapse area, assistance with demolition and temporary stabilization procedures, design of grillages and analysis of existing structures to support construction equipment, coordination of the survey monitoring of existing damaged structures, and inspection of hundreds of buildings in the area surrounding the collapse site.
