The protection screen is wrapped around the entire perimeter of the building for four levels, and will climb up the 65 stories with hydraulics, no crane is needed. The top part of the screen was designed to fold down, which makes resetting of the slab formwork easier. The hinged top part of the protection screen is a big safety advantage in all stages of the project since the slab edges are protected with the screen as soon as the hinged part is set back in place after lifting up the slab formwork. In addtion, the hinged part is completely sealed with rubber between the screens and also to the slab edges to keep heat in the required area.
In addition to the protection, Doka engineering designed loading platforms built into the screens to allow storage for the vertical formwork close to where the actual work is happening to reduce crane time.
One of the major challenges is the complicated slab edge outline. 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 every other level, approximately 5,800 mm.
The contractor, Hardwall Construction Ltd., was pleased that Doka provided a complete protection screen solution, which can take the changes in the building, is able to hinge down and has loading platforms all the way around the building.
"The Doka Hinged Protection Screen has provided the jobsite with a safe & fast system. It accomodates on-site material storage, public safety and winter heating requirements." Angelo Furgiuele, Hardwall Construction, Ltd.
