1926-1996

Referred to locally as “Plant One”, the Cummins Engine Plant is a 1.4 million sq ft manufacturing facility that opened in 1926.

Harry Weese designed major expansions to the Cummins Columbus Engine Plant in 1960 and 1965, creating a large manufacturing facility around the existing structure. In 1996, Kevin Roche added a significant expansion on the east side of the plant, incorporating office space and a new Central Avenue entry. A tree-lined boulevard leads to visitor and employee parking, emphasizing the plant’s dual role as a manufacturing hub and a civic landmark.
