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!
