There is an impressive curved steel building currently being erected in Seattle, WA. right now! For The Spheres, Albina’s scope of work included approximately 750,000# and 1.050 pieces of bent steel material consisting of TS 9" X 5" X .500" WALL A500 GR B, TS 10" X 6" X .500" WALL A500 GR B, and TS 12" X 8" X .500" WALL A500 GR B. The curved steel sections were bent the easy way and a portion bent off-axis. All material is AESS with very tight tolerances. The project consists of 8 miles of welds and 8 miles of grinding performed by the lead fabricator! 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. The bends fit to fixtures (fabrication) within 1/32nd of an inch! Almost NO correction was needed during fabrication or erection. [caption id="attachment_750" align="aligncenter" width="300"]
