Designed by world renowned architect Cesar Pelli (the architect of the Petronas Towers in Malasia), the BOK Center features a curving glass curtain wall measuring 600 feet in length and 100 feet tall while leaning back 5 degrees with the horizontal members also on 6 degree slope while also on a segmented curve.  Meaning there is not one piece of glass in the 1,600 units in this iconic wall (literally called the ICON Wall) that is the same size or pattern and not one square corner on any of the units.  Even more impressive, this project was designed using cutting edge technology that was still in its infancy “BIM” and the entire wall was pre-fabricated and all glass was pre-ordered before the structure was erected.
