Officials began inspecting the damage of Notre Dame Tuesday. They declared the cathedral structurally sound while identifying “some vulnerabilities,” according to French Deputy Interior Minister Laurent Nunez. Specifically, the vault and gable of the north transept were of concern. Inspectors are also worried about structural damage that may be hidden.
Kirk Martini, a professor at the University of Virginia School of Architecture with a doctorate from the University of California at Berkeley in structural engineering, said the transept is probably the greatest vulnerability. To ensure the structure is stable, additional shoring may be necessary after the full extent of the damage is assessed.
