Floating staircase structure
The Architect specified the project as one of the most difficult jobs ever done. “The stair, which extends from the cellar floor to the second-floor gallery ceiling, is suspended on 300 6mm 1×19 stranded wire cables tensioned to approximately 900 pounds. Each of the woven stainless-steel stringers, which list a minimum breaking strength of 22.0 kN, measures ¼ inch in diameter. Spacing is 2½ inches on center to also function as a balustrade.
The stair is assembled into four main sections with two separate landing sections. Four cables penetrate each tread, and each cable is single-span, so the visual vertical alignment is what provides the architectural splendor. To weld each plate to each other and to accurately drill the multitude of holes for the cable spacing, was the tough part. To our surprise the lineup of the holes was better than expected.”

When the Bridge Is the Architecture
Safety That Earns Its Place The best safety systems on high-design projects share a common trait: they solve the engineering problem without creating a visual one. At the Passerelle A9, Webnet does exactly that — a compliant, load-rated fall protection system that integrates into the bridge's architecture rather than sitting on top of it. If you're working on a bridge, overpass, or elevated structure where standard guardrail systems feel too heavy, Jakob's team can work through the options with you.
