TheG. Fred DiBona Jr. Building, formerly known as theBlue Cross-Blue Shield Tower orIBX Tower, is askyscraper inPhiladelphia,Pennsylvania housing theheadquarters ofIndependence Blue Cross (theBlue Cross-Blue Shield-affiliated organization in thefive-county Philadelphia area). The tower, built between 1988 and 1990, was designed byWZMH Architects, who also designed theCN Tower inToronto, Ontario, Canada. It was renamed in 2005 after the company'spresident andCEO,[3] mapped who died of abrain tumor at age 53.
Construction of the building consists of a steel skeleton surrounding a reinforced concrete core, similar to the construction of the newComcast Center. The exterior is all blue glass except for granite accents at the base on the eastern and western facades and granite columns at the main entrance. It is currently the eighth-tallest building in Philadelphia.[1]
The building was originally intended to have a twin tower just to its west but the office-space requirements of the company ultimately ended plans for it.[3] That lot remained vacant until an apartment building was built on it around 2015–2016.
Alain Robert, the famous "French Spider-Man", scaled the building to the 44th floor in 1997, two years after the back-lit Blue Cross logo was added to the building's pediment.
