“The Seattle Spheres” win Presidential Award for Excellence in Fabrication

The May 2019 Edition of Modern Steel Magazine features an article on the Seattle Spheres as they won the Presidential Award for Excellence in Fabrication! 


Albina Co., Inc. was the steel bender/roller for the Curved Steel Bio-Sphere buildings in Seattle, WA. Albina bent 750,000# and 1,050 pieces rectangular tube steel bent the easy way and a portion bent off-axis. Almost 8 miles of welding work and grinding was avoided because of Albina’s ability to bend a portion of the project. Almost NO correction was needed during fabrication or erection as the bends fit to the fixtures within 1/32nd of an inch!

Curved Steel Bio-Spheres Take Shape in Seattle, WA.

The erection of the curved steel “Spheres” in Seattle, Washington was completed in April 2016. Over the summer, the team of contractors began the install of the glass enclosure over the steel bio-spheres. Check out the progression in the pictures below. As a reminder, Albina’s scope of work included approximately 750,000# and 1.050 pieces of rectangular tube steel bent the easy way and a portion bent off-axis. The material was bent to tight tolerances and bent to AESS standards. The amount of welds and grinding was significant, but thanks to Albina’s ability to bend portions of the project, a significant amount of welding and grinding was avoided. Almost NO correction was needed during fabrication or erection as the bends fit to fixtures (fabrication) within 1/32nd of an inch! Check back for more pictures as the project progresses!
