Construction on the permanent campus began in June 1967 with the Technology building and proceeded in phases. With the opening of the Learning Resource Center in 1974, the original campus plan was essentially complete, except for some athletic facilities and the Performing Arts Center, a large auditorium planned for the area now occupied by the soccer field, but never built. The original Cernan Space Center building, located north of the Learning Resource Center, was plagued by latent construction defects, and, after being used for several years, was demolished and replaced by the present building located nearby.
