CRANBERRY TWP — Crews are about 75 percent complete with construction of the new Cardinal Wuerl North Catholic High School that’s slated to open in August 2014.

Michael Arnold, the chief facilities officer for the Catholic Diocese of Pittsburgh, said Wednesday that the project remains on schedule and that construction on the school should be done by the end of January.

“Things are moving along very well,” he said.

After January, crews will work to build the spacious, 265-seat chapel, which will be at the center of the school both physically and spiritually. It will be the last part to be done.

Construction crews already have completed the skeletal interior of the school, as well as finished most electrical and duct work. They’ve also completed the 1,250-seat gymnasium, and the student parking lot has been paved.

Most recently, Arnold said, crews are working on finishing dry wall, painting, floor tiling and carpeting.

“The building’s facade is essentially complete with the roof, windows and glass,” Arnold said. “Now we’re entering into some of the finishing work.”

Officials broke ground on the project in June 2012 and construction has progressed since then.

The school is on 71 acres near Cranberry Township’s border with Seven Fields on the north side of Route 228.

The 180,000-square-foot building will house more than 1,000 students in grades 9-12. The project is estimated to cost more than $70 million.

In addition to construction, the school also got a new principal several months ago when Diocese officials named Kellie Abbott to that post.

Abbott, who is working on a doctoral degree at the University of Pittsburgh, had previously been a principal in the Pittsburgh Public Schools system in addition to teaching English in the Seneca Valley School District.
