BOK Park Plaza Tower

Oklahoma City

As the sixth-tallest building in the city, the 27-story cast-in-place office tower houses the Bank of Oklahoma and Devon Energy, with additional space available for office and retail tenants. Two parking garage structures, one precast concrete and one cast-in-place, hold over 1,600 cars. The project also connects to the Downtown OKC Underground system and includes two skybridges to connect the tower to the commercial property across Hudson Avenue via the north garage.

Walter P Moore’s Secure Design specialists were engaged early in the design phase to provide a threat and damage assessment for the new tower. As part of this effort, our engineers worked closely with the developer and design team to establish appropriate explosive and vehicle ramming threats for consideration. Walter P Moore performed analysis to understand the level of protection and extents of damage for an unhardened building for each threat size. We studied various mitigation methods for the structure and building envelope before meeting with the owner and design team to formulate a comprehensive protection strategy.

Our team worked closely with the architect, landscape architect and design team to coordinate vehicle barriers and structural hardening, including strengthened floor systems to protect against vehicle borne explosive devices, and column protection for areas of uncontrolled public access and exposed columns to protect against satchel-carried and vehicle borne explosive devices. The close relationship of structural and secure design services, both provided by Walter P Moore, allowed for the seamless integration of effective structural hardening and efficient construction administration of security components.
