The 55,000-sq-ft National Veterans Museum has three concentric rings up to 60 ft tall and 300 ft in diameter and a walking ramp that connects the front door of the plaza to the green roof amphitheater. The concrete ring superstructure is a non-circular ellipse with ever-changing radiuses designed using NURBS software. The structure’s geometric complexity had little to no dimensions shown on the design documents. So, working with ownership, design and engineering to overcome this challenge, the Turner-led construction team developed and built the entire project utilizing a detailed 3D virtual model, a 3D-printed scale model and a very tightly coordinated daily surveying and layout process.

To deliver the concrete structure, Turner, Baker and Titan Reinforcing segregated it into 49 individual placements. Pour joints were set after extended structural review periods, and each approved individual placement was a planned and executed project in itself. The finished product is a distinctive design that honors all veterans who answered the call to service.
