Robert Morris University bought the dome—which is 240 feet wide, 350 feet long and 70 feet high—in 2003. It's on Neville Island, west of Pittsburgh, a few miles from the school's campus in suburban Moon Township.
The dome houses a driving range, miniature golf courts and office space and is made of Tedlar, a fabric that is supported by air pressure.
Nobody was hurt when the microburst ripped the fabric on June 1, causing the dome to collapse. The torn panel was being replaced this week in hopes contractors can inflate the dome starting Wednesday.
The school hopes to reopen the dome by month's end.
