Mark “Fritz” Hefel worked for Conlon Construction for more than 35 years. For over 30 of those, he was superintendent on projects at the University of Dubuque. He not only built countless buildings on campus, he built lasting friendships with the students, faculty, and staff. Upon his retirement, to honor Fritz, The University of Dubuque and Conlon Construction collaborated on a dedicated space on campus where students can congregate and relax. The patio and fire pit just outside Heritage Center will forever be known as the Hefel Hangout. Conlon has also established a student scholarship fund in his name.
