Tyler Wirth UC Calhoun Co-op Tour_2

What's it like to be a Messer co-op at a project?

Tyler Wirth, a University of Cincinnati student working as a project engineer co-op at Messer, was featured in the Cincinnati Enquirer (photo credit Andrew Higley / University of Cincinnati) to discuss his day-to-day responsibilities while working on the University of Cincinnati Calhoun Hall renovation.

  • "I feel like firsthand work experience is most important when you're going into a career, no matter what it is," he said. "You don't get the hands-on experience in classes."
  • One of Wirth’s goals when he started his fall co-op was to work on his communication skills. He says he’s gotten daily opportunities to do this by running morning meetings with the foremen, and he can already tell he’s getting better.
  • Wirth says he’s walked the building top to ground floor at least 50 times by now, doing safety walks three times or more each week. He likes being in the know about construction at the university.
