Class is back in session at East Valley High School Friday after construction workers finished stabilizing concrete in the school’s former library.

Classes were canceled Wednesday and Thursday after shifting concrete on the southeast side of the former high school library was discovered at roughly 3:30 p.m. Tuesday after students left campus. That part of the building has not been in use during a school remodel and construction project.

Superintendent John Schieche said supports were installed to reinforce the building on Thursday and were finished in the evening.

“School operations are on schedule as usual,” he said of Friday classes.

The building where the shifting concrete was discovered is a “significant distance” from classrooms used by students and staff, the district said.

The high school, which has 888 students, has been under construction since March 2018 for renovations and expansion approved by voters in a $42 million bond.

A renovated cafeteria and more than 20 new classrooms opened at the start of this school year. Additional work will continue through the school year and is expected to be completed ahead of the 2020-21 school year.

The former school library, where the shifting was discovered, had been partially demolished and will be converted into a new band room. Additional demolition is expected near the site, but parts of the building will remain, district communications

director Brittany Kaple said earlier this week.
