The Hyatt Regency, located atop the Bethesda Metro station and minutes from downtown D.C., features an award winning staircase the newly reimagined lobby space. The Ernest Wiemann Top Job Contest is a peer-judged competition created to honor outstanding work. The staircase, fabricated by Emerald Ironworks, took home a silver Ernest Wiemann Top Job Contest Award in the "Commercial-Stairs Complete" category. 

The interior stringer of this "floating" staircase has five different radii. The stringers had to be clad in wood and the steps in Italian marble. Most impressive, ot steel stringers installed to within 1/32" tolerances. Materials bent for the staircase included:

TS 18" X 6" X .625" WALL A500 GR B

               1 pc spiral bent the easy way to a 143 ft plan view radius

               1 pc spiral bent the easy way to a 14 ft plan view radius

               1 pc bent the easy way to a 17 ft radius

When guests walked into the Met Gala’s Great Hall, they were greeted by the Statue of Liberty’s eternal flame of enlightenment at the centerpiece of this year’s ball. Albina bent the 1” pipe framework for the ribbons of a towering spiral staircase leading to the shimmering flame. When our customer received the bends, they had this to say:

"We received the bends and they look great! I appreciate that everything was checked and well labeled before you guys sent it out. It was a pleasure working with you and I hope to do business in the future."

The centerpiece was featured in Vogue Magazine  and a time lapse of the erection can be seen on Instagram.  Below are a few pictures from the fabrication and erection processes.

The Buddy Holly Hall of Performing Arts and Science in Lubbock, Texas is a 220,000 square foot state-of-the-art campus featuring two theaters, event space, a full-service bistro and a ballet academy under one roof. Albina bent various materials for the signature spiral staircase in the Christine DeVitt Lobby. See the video below to get a sneak peek inside!

The projects is featured in the May edition of Modern Steel Construction. For more details on the entire project and to see a full list of winners check out AISC's website.
