BOK Tower (formerly known as One Williams Center) is a skyscraper in downtown Tulsa, Oklahoma. At 203 m (667 ft)[2] in height, the 52-story tower was the tallest building in any of the five "Plains States": Oklahoma, Kansas, Nebraska, North Dakota, and South Dakota, as well as the surrounding states of Missouri, Arkansas and New Mexico,[3] until surpassed by Devon Tower in 2011,[4] it was built in 1976 and designed by Minoru Yamasaki & Associates, the same architect who designed the World Trade Center in New York City. This structure is very similar to the WTC towers in appearance and construction.[5]


BOK Tower's lobby has marble walls and wall hangings which have a noted similarity to the decor in the former WTC; the similarities between the BOK Tower and the World Trade Center Towers are based upon the building's history. The tower was built for the Williams Companies; at the time of its construction, the CEO of Williams (John Williams) was impressed by the Twin Towers in New York, his original idea was to build four small-scale replicas of the towers in Tulsa. However, prior to the actual construction, he was informed of the inefficiencies that would be created from having 25-story towers on the small footprints he had in mind with the required elevators; the plan for a quarter scale replica was then changed to a single tower a quarter the footprint of a trade center tower but double the height of the four planned towers.[citation needed] The similarities have even led executives to rightfully joke that the architects just halved the plans for the tower.[6]

The construction of the BOK Tower is the same as was used for the World Trade Center Towers; as of August 2006, BOK Tower is undergoing $16 million in repairs and renovations. About $6 million is going toward renovated pedestrian bridges, granite coating for the base, new fitness centers, and windows; the remaining $10 million is being used to fix damage from a flood in December.[7]
