Frameless Elevator Shaft and Glass Stairway, Giroux Glass Inc.

After being contacted by architecture firm C.J. Light Associates and general contractor Andrew Williams, Giroux Glass became an integral part of designing this “frameless” glass elevator shaft and stairwell at an exclusive beachfront property on the southern coast of California.

After some thorough layout, the Giroux in-house drafting department constructed a digital 3D model of the entire area in Solid Works, from which the design team would work. Later, the model became the template for ordering and fabricating all of the elevator shaft and stairwell components.

The first challenge this project presented the Giroux team was the design and engineering of a stringer that would free span from the second to the third floor. For this, Giroux solicited the expertise of Andrew Nasser, a structural engineer whom Giroux often works with. Once the requirements for the stringer and treads were calculated, the next hurdle was to retrofit the existing wood structure with enough steel to structurally support the stringer and stair. Cundiff Steel fabricated and installed all of the support steel, 38-foot elevator guide rails and the 2-inch by 12-inch steel helix for the stringer. The third and final hurdle was the design and engineering of a frameless, 6-foot cylindrical elevator shaft that was to stand 30 feet tall. The design intent was to utilize minimal support clamps for a “frameless” look.

All of the 9/16-inch bent tempered, laminated glass and 1-inch tempered, laminated treads were fabricated by Cristacurva and installed by Giroux Glass
