As the GC, the author needed to provide the correctly dimensioned hole through the floor ...
... and provide a “pit” (formed into the concrete slab) at the bottom as a base for the frame
The shaftway frame is installed and secured to the basement, first-floor framing and ceiling.
The cab is driven by a motorized hoist, located at the top of the shaftway, with all the wiring coming from the attic above.
The installation was managed by Savaria, the manufacturer, freeing the author from the delivery and long-term service of the unit. On this install, it helped that the jobsite had ample room to lay out the curved glass panels for the walls of the shaftway.
As the general contractor, the author helped oversee the installation, making sure that finish flooring was protected from the scaffolding needed to install the glass panels and that balcony glass aligned with the elevator door. All glass surfaces were protected until the end of job.
