ONEOKs Operation Center, located in Mont Belvieu, Texas, includes a control room and staff building. ONEOK is a leader in the gathering, processing, storage and transportation of natural gas. The project required a safe and serviceable design to provide an enhanced work environment for ONEOK employees.
