COLUMBUS, IN — HOK’s design for the renovation of the six-story Cummins Technical Center in Columbus, Indiana, has transformed the landmark tower, originally designed by mid-century modernist Harry Weese, into a new workplace. The 72,000-square-foot office space spans five floors, accommodating approximately 500 employees focused on research and development for Cummins’ next-generation power solutions.
“The reopening of the CTC office tower marks an important milestone for Cummins and our Destination Zero strategy,” said Jennifer Rumsey, Cummins Chair and Chief Executive Officer. “Much of the research and development [R&D] for our next-generation power solutions start right here in this very hub.”
The project modernizes Cummins’ first and longest-standing technical center, which revolutionized the company’s R&D capabilities when it opened in 1968. As Cummins invests in future technologies, the renovated building continues its role as an innovation hub.
HOK’s design emphasizes collaboration and innovation throughout the office space. Key features include a new interconnecting stair, two social hubs, and more than 90 conference rooms of varying sizes with stadium-style seating. To support employee well-being and inclusion, the design incorporates gender-neutral restrooms, nursing rooms, quiet spaces, and treadmill desks. The team also integrated soft lab zones and expanded collaboration areas throughout the building.
“Our design respects Weese’s modernist legacy while creating the dynamic, flexible workspace Cummins needs for innovation,” said Kelly Lott, Practice Leader for HOK’s Interiors group in St. Louis, Missouri. “The result maintains the building’s architectural integrity while supporting the collaborative culture essential to Cummins’ engineering teams.”

The design celebrates Cummins’ heritage by incorporating plus (+) symbols in featured spaces, honoring graphic designer Paul Rand, who created several of Cummins’ historic logos. The renovation also includes practical updates like upgraded lighting systems and functional window blinds.
“I am grateful to our CTC employees for their patience and perseverance during this much-needed renovation,” said Tim Frazier, Cummins Vice President - Research & Technology. “We are so glad to have our Cummins HELM engineers, technical specialists, and innovators together again under the same roof working as a coordinated team, close to the technology and testing being executed here.”
The renovation, constructed by F.A. Wilhelm Construction Co., was completed after a three-year process.
