Bradford Allen and Andretti Global joined Clark Construction Group recently to celebrate the topping-out of Andretti Global’s new headquarters in Fishers, Indiana. The nearly 400,000-square-foot facility, part of a larger 90-acre campus, more than quadruples the size of Andretti’s current headquarters.

“We are so proud of the progress that has been made on our future home, and we are honored to be a part of today’s topping-out ceremonies,” said Michael Andretti, chairman and chief executive officer, Andretti Global. “It is no small feat to get to this point with a project of this magnitude, and we could not have done it without our partners at Bradford Allen, Clark Construction, RATIO and Ridge.”

In addition to housing day-to-day operations for the racing team, the building will be home to the advanced research and development of Andretti Technologies. The design was planned by U.K.-based motorsport design consultants Ridge and Partners and Indianapolis-based international design firm RATIO. Clark Construction is the general contractor.
