BOK Tower TI

Office

Tulsa, Oklahoma

Brief Summary

Designed by the same architect who designed New York’s World Trade Center, the BOK Tower building is Tulsa’s tallest skyscraper and iconic beacon of the downtown landscape. Originally named the Bank of Oklahoma Tower when it opened in 1976, it’s only fitting that BOK Financial would want all internal departments within this emblematic monument of Tulsa’s financial sector.  

This robust office expansion included 165 offices and 35 conference rooms, spanning five floors. Each floor features its own reception space, training rooms, bread room, coffee bar, mothers’ room, mail room, and file room, as well as data and phone rooms. The restrooms were modernized with high-end materials, including floor and wall tile, stainless steel toilet partitions and accessories, and solid surface counter tops. Crossland enhanced the elevator lobbies with beautiful herringbone floor tile pattern, wood wall panels, and wood ceilings that align visually with the project’s wood doors and millwork. Storefront was well utilized for every office and conference room. Almost all the project’s glass is reeded, designed with convex ridges across the surface of the glass. Significant updates to mechanical, electrical and plumbing systems were also necessary.
 
Coordination between the Crossland teams and building management played a key role in the success of this project. Given that only two freight service elevators were available for material and worker transport, detailed scheduling protocols were implemented for deliveries. Construction that was especially loud was carefully planned to occur following normal business hours to prevent from disrupting occupied floors.  

As a result of meticulous planning and scheduling, the BOK Tower project was seamless, from demolition to completion.

Designed by the same architect as New York’s World Trade Center, BOK Tower is Tulsa’s tallest skyscraper. Originally named the Bank of Oklahoma Tower in 1976, BOK Financial hired Crossland to renovate five floors, bringing all internal departments within this emblematic monument of Tulsa’s financial sector.  

This robust expansion modernized 165 offices and 35 conference rooms, spanning five floors. Each floor features its own lobby area, plus break rooms, mail rooms, and data/phone areas. The elevator lobbies were enhanced with beautiful herringbone floor tile, wood wall panels and wood ceilings, to align visually with the project’s elegant wood doors and millwork. Much of the glass used for the project is reeded, providing a contemporary look and feel.  

Elevator limitations and other businesses operating in the building required meticulous planning to keep the project moving forward in a timely fashion. Daily coordination between Crossland teams and building management resulted in a seamless renovation, from demolition to completion.
