Cina Hall, located inside the University of Minnesota Duluth, is re–opening in time for the start of the new school year.
The $4.6 million renovation is the first time the building has been updated in more than fifty years.
It's one of the busiest buildings on campus, housing the College of Liberal Arts programs. The 15 month renovation includes many changes like safety upgrades and fire doors.
John Kessler, the Project Manager, said "We added air handling systems which included air conditioning. It didn't have a fire system and it was all upgraded to current codes."
Classrooms were also painted. Each floor of the four story building has a theme. Cina Hall was designed to represent the American Indian Studies department.
During the renovation, more than 70 faculty and staff members were relocated to other buildings while five trailers stored their office furniture.
