Cummins Inc

Designed by Kevin Roche (Kevin Roche John Dinkeloo and Associates) the Cummins Corporate Office Building, completed in 1984, serves as the world headquarters for Cummins, Inc., a Fortune 200 Company and diesel engine manufacturer. The one-story building with a mezzanine level occupies three blocks in downtown Columbus.

The zigzag plan configuration interacts with a park-like setting on the east side of the building, defined by a portico surrounding the four-story historic Cerealine building, which serves as the employee cafeteria.

The office building is primarily cast-in-place octagonal concrete columns with infilled precast concrete spandrels and narrow windows to provide noise and sun control.

From the Roche Dinkeloo website :

• An arcade of columns connects the two embracing ends of the main structure and establishes both the continuity of the street line and the containing wall of the public garden. The strong exterior column expression relates to the portico of the adjacent Post Office Building; and the materials, enclosed garden, and pool also relate to one of the earliest modern buildings built in Columbus - the Tabernacle Church of Christ designed by Eliel Saarinen in 1940, which is located on the other side of the business district. The corner of the building nearest the center of the City is cut away to provide a visitor's entrance and also to recognize the small park across the street, which is an integral part of the expanded Irwin Union Bank and Trust Company.
