The Spheres are three intersecting steel-and-glass spheres enclosing five freestanding floors, and serving as the centerpiece of a new urban corporate headquarters in downtown Seattle. Marne Zahner, the Structural Project Engineer for the Spheres, will present on the collaborative design, fabrication, and construction processes behind this unique structure. Main topics will include:

  • The origins of the project and the architectural vision
  • The development of the steel structure’s unique geometry was a highly collaborative effort between architect, engineer, façade consultant, fabricator, detailer, erector, and general contractor; the presentation will give specific examples of how collaboration improved the final result. 
  • A discussion of the role parametric modeling played in the architectural design, structural analysis, and steel detailing
  • The unusual challenges posed by the unique structure

Benefits and knowledge our members can expect to take away from the presentation:

  • The latest steel detailing and fabrication techniques
  • A case study of the successful execution of a collaborative, design-assist-based project delivery method
