Displaying modern opulence in the midst of a bustling business district, the 65-story Shangri-La Hotel in Toronto will offer lavish accommodations for discerning guests. The extravagant, 200-room hotel will occupy the first 17 floors of the development, while luxury condominium residences will be located on the upper levels.
To keep the work area safe and protected from weather, Doka’s, Little Ferry, N.J., foldable Xclimb 60 protection screen is being used. Just as important, the screen protects the people in the busy Toronto area from falling debris from the work site. The protection screen envelops four levels and is wrapped around the entire perimeter of the building. It will climb up the 65 stories with hydraulics; no crane is needed. Once it lifts the slab formwork, the top part of the screen folds down to make resetting of the formwork easier and to provide better protection for slab edges.
To reduce crane time, the formwork company’s engineering team designed loading platforms built into the screens to allow storage for the vertical formwork close to where the actual work is happening.
The major challenges are the changes on the slab edges. In the building’s design, the outside perimeter of the east side changes at every level. The edge of the building waves in and out irregularly. Then, starting on level 50, the slab edge in the center of the west side steps in and out approximately 5800 mm every other level.
The formwork company provided Framax wall formwork for the building core, stair cores, shear walls, and columns.
The contractor, Hardwall Construction Ltd., was pleased with the complete protection screen solution, which can handle the changes in the building, hinges down, and has loading platforms all the way around the building.
The Shangri La Hotel is scheduled to open in spring 2012.
