Overview

At 850 feet, the 50-story world headquarters building for Devon Energy is the tallest building in Oklahoma. Thornton Tomasetti provided structural engineering for the office building, which houses a seven-level rotunda, a six-level podium and below-grade parking. The scope of services included a vertical expansion and addition to an existing precast concrete garage that connects to the new tower.

The tower features a concrete core structural system with concrete framing from the core to exterior. Its three-sided base is enclosed by a cable net wall that spans three floors. A seven-story, 120-foot tall glass rotunda with architecturally exposed steel, interior balconies and a glass roof serves as the entrance and provides space for special events. A crown extending 60 feet above the roof tops off the tower. Among the project challenges was a water table 10 feet above basement level, which was addressed with a 12-foot mat under the tower core, secant piles, piers in sandstone and a specially designed ballast slab.

The building was designed to achieve LEED Gold certification and includes a landscaped plaza above the below-grade parking structure.
