DLR Group

Barnum leads the firm’s global sports studio, and the recent $315 million renovation and modernization of Los Angeles Memorial Coliseum was the latest in an architectural career that has spanned 35 years. Since coming to DLR from HOK in 2000, the Iowa State grad’s résumé includes Pinnacle Bank Arena in Lincoln, Neb.; CHI Health Center Omaha; West Texas A&M’s new football stadium; and FedEx Field’s 30-foot-tall “Solar Man,” a working solar system that is also a work of art. Tingle, who joined DLR Group from Skanska in 2017, is known for his work on Class AAA ballparks in Durham, N.C., and Wichita, Kan., as well as Petco Park, where it was his idea to put the left field foul pole on the corner of the iconic Western Metal building. His work also includes the Spectrum Center in Charlotte and renovations at Kentucky’s Commonwealth Stadium and Cincinnati’s Fifth Third Arena. — D.B.
