Did the dome last as long as it was designed for?

After an ice storm in December 2015, the 13-year-old dome collapsed. It housed several events for indoor track athletes, including practices and meets, practice room for all winter sports teams, physical education classes, and various community events.

The dome was designed by Air Structures American Technologies Inc. and cost $3 million at the time of its construction in 2002. It was meant to last 15–20 years.

No, it did not. The dome only lasted 13 years, but it was designed to last 15-20 years.
