National Veterans Memorial and Museum
Location: Columbus, Ohio, USA
Completion Date: 2018
Project Details: The unique engineering of the museum is defined by a custom design cast-in-place concrete arch superstructure and a complex exterior curtain wall. The building was constructed from nearly 28 million pounds of concrete, and features a glass curtainwall system and spiral processional ascending to a rooftop sanctuary. The concrete ring superstructure is a non-circular ellipse with ever-changing radii. For construction purposes the structure was 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 as a project in itself.
Scope of Work: DBM Vircon was retained on this job to provide expert 3D modeling of the select foundation areas, and worked closely with Gerdau’s in-house detailing team. The structure’s geometric complexity required dowels from the foundations be detailed in ‘bands’ to match the varying angled bars in the walls. The rebar wall cages were assembled in the yard around the construction site and lifted in placed to be tied together.
Project Awards: This project was awarded the “Most significant construction project of 2018” by the Associated General Contractors of America.
