In this project, the company provided the full scope of work for all the Ornamental and Miscellaneous steel within the National Museum of African American History and Culture. Included within this spectrum of items was one of the most design demanding and complex parts of this course of work, a monumental stair unlike any other preceding it. This stair included multi bevel, multi radius, compound breaks formed through a very complex layout and fabrication process. This stair utilized a wide array of materials including massive rolled Cor-Ten sheets, custom bronze illuminated handrails, and a continuous 100ft elliptical box stinger with no intermittent supports. Though this complex design and make-up this stair still prevails a sophisticated, sharp, and elegant egress entrance holding onto the aesthetics of true modern art.
Some of the key points of challenges within this project could be defined under 3 main points, design/detailing, size of materials/stair, and precision of fabrication.
