Sinkhole opens at new Penn Hills High School
Penn Hills School District officials were working to fill a sinkhole at the new high school on Collins Drive.
Officials on Friday morning discovered the sinkhole on the south side of the building, about 10 feet from a retaining wall.
The hole was about 3 feet wide and 30 feet deep.
District construction manager Dennis Russo said it is the result of old mining activity.
“The engineers and I believe that the rain we received on Thursday finally put enough pressure on the old mineshaft to cause it to collapse,” Russo said, adding that a grout-pumping truck was on site and the problem would be fixed later in the day.
The high school opened in January at a cost of about $58 million.
