HKS, Inc. is the architectural firm responsible for the stadium’s design, with Walter P Moore working as the Structural Engineer of Record. The stadium features a retractable roof and window wall, thus allowing the Colts to play both indoors and outdoors. The surface is FieldTurf. The elements of kinetic architecture will provide for quick conversion of the facility to accommodate a variety of events. On February 28, 2006, Indiana native Forrest Lucas announced that his company, Lucas Oil, purchased the naming rights for $121 million over 20 years.
