About 200 students and faculty members hurried out of the law school at the University of North Carolina at Chapel Hill on Friday when exterior brickwork bowed away from part of the 40-year-old building, cracking concrete and breaking glass.
According to The News & Observer, a newspaper in Raleigh, N.C., the law school’s dean, Jack Boger, blamed this summer’s extreme heat for the wall’s failure. In a message posted on the law school’s Web site, Mr. Boger said engineers had concluded that there was “no threat to the structural integrity of the building.”
“All floors, walls, and ceilings are sound,” he said. “The exterior facade, however, needs reconstruction, which is estimated to take a month or more.”
Students and professors said the evacuation went smoothly.
