Blacksburg, Va., school officials knew of structural problems before February gym roof collapse

From The Roanoke Times: For more than 10 years leading up to the collapse of the gym roof at Blacksburg High School in Blacksburg, Va., school administrators knew of significant structural problems inside the school and, particularly, the gym. Three separate engineers hired by the school district warned the district’s facilities director that cracks and settling in the building's foundation must be evaluated more closely or permanently fixed, according to engineering reports from 1999 to 2004. The roof collapsed in February.
