60+ Years of Design + Innovation

Reinforcing a Healthy Workplace

Wellmark Blue Cross and Blue Shield
Headquarters and Operations Center

Des Moines, Iowa, USA

“Knowing this facility will be around for many, many years to come, we pushed ourselves to do more in terms of sustainability.”

John Forsyth
Chairman and CEO, Wellmark Blue Cross and Blue Shield

This new headquarters is the world’s largest single owner-occupied office building to earn LEED Platinum certification.

With its dramatic signature curve and thin structural steel edges, the building establishes a new visual presence in Des Moines while promoting a healthy environment for Wellmark’s people.

The facility accommodates up to 1,750 employees and includes general office space, a cafeteria, a data center and a conference center. A sky bridge links the office building to a 1,650-car parking garage and an employee fitness center.

The complex shape, which features three different building orientations and an elliptical curve cut into its core, required a unique engineering solution.

Thinly profiled steel enhances the structure’s design details. This is evident in the two stairwells, known as “lanterns,” that form the bookends of the building’s elliptical curve. Encased in glass and featuring architecturally exposed structural steel, these stairwells challenged the structural team to design a support system that created the appearance of a floating stair element within the transparent facade.

To maximize the daylighting that reaches the building core, the design carefully positions structural columns, cantilevers floor framing and limits the depth of framing members. The natural light provides building occupants with a healthy indoor environment that supports wellness and productivity.
