An engineer's report says a wing of a private Cincinnati school collapsed in January because construction crews were digging too close to the foundation. No one was hurt in the collapse, which happened on a weekend. The report by THP Limited says workers at the Summit Country Day school took out too much of the earth that support the wing's south wall. The 114-year-old school had been undergoing an eleven (m) million dollar expansion. The collapse caused the school to cancel classes for a week. Some classes were later moved some to Xavier University and a nearby church. Engineers have inspected the school's other campus buildings and say they're all sound.
