An independent engineering report prepared for the University of New Mexico about its Albuquerque indoor practice facility found that wind pressure could enter the building through openings in the structure and not escape, putting the training facility at risk of collapse. The investigation by Chavez-Grieves Consulting Engineers in Albuquerque found the school’s steel-and-fabric facility had been designed by Summit Structures, Allentown, Pa., as an enclosed building.

Currently, the university uses the facility only when the louvers and doors are closed and the wind
