For the past several weeks, construction crews installed at the Stantec Tower have been working on one of the most complex components of what will become Edmonton's tallest building. At the separation point between the office and residential portions of the building, a series of steel outriggers will serve to stabilize the 251-metre-tall skyscraper. A two-metre-thick transfer slab will then be built to enable the rise of the residential floors.

The intricate task is a necessary step in the construction of a 66-storey building with disparate internal programs and floor configurations. The steel trusses that have been placed atop the tower were assembled in Quebec and shipped to the site, where they are now being sealed within concrete above the 29th floor.

A three-dimensional structural model of the tower shows the extensive piling network underground, the thick midsection transfer slab, and the changing width of the building's columns as it makes the move from office to residential. Another set of stabilizing outriggers will be added to the top of the building when vertical construction concludes.

The 483-unit SKY Residences will occupy levels 30 through 66, giving residents the highest views in the city and access to a sprawling amenities floor at the segue between the two uses. An 11,000-square-foot rooftop terrace with several barbecue stations and outdoor seating areas will join an interior array of features that includes a business centre, fitness room, and catering kitchen.

The first half of the tower, where the offices are situated, are expected to be delivered in 2018. The residential component is then scheduled to see residents pour in the following year.
