The Terracon Foundation has been making grants to individual CEE students for more than 25 years. This is the first year a grant is being awarded to a capital campaign for CEE engineering education facilities at the University of Illinois.
“We are deeply grateful to Terracon for all their support over the years, but especially for this latest gift to the CEE Modernization Project. Their generous gift in support of the Geotechnical Engineering Instructional Laboratory honoring some of the great geotechnical engineers of the department’s history – Karl Terzaghi, Ralph Peck and Don Deere – will inspire and benefit students for generations to come,” said Benito Mariñas, Ph.D., head of CEE at Illinois.
