A part of new seating being constructed at TCU's Amon G. Carter Stadium collapsed early Friday morning.

Concrete seating for about 100 people in the south end zone collapsed and crushed older seating below around 2 a.m., according to TCU spokeswoman Lisa Albert.

No injuries were reported and the area was blocked off as a precaution.

The project will add an additional 28,500 square feet to the athletic complex and renovate 6,400 square feet of existing space to TCU’s football stadium.

The project is scheduled for completion in July, but TCU officials were not sure how this might affect the stadium for the beginning of the football season.

No cause of the collapse was known.

"Structural engineers and the general contractor involved in the project are conducting a through and comprehensive investigation to determine the cause," Albert wrote in an e-mail to TCU students and faculty. "Additionally, TCU will hire independent structural and design engineers to conduct a separate review and examine all findings."
