Construction on the new roof is expected to start soon. The 720,000 square feet air-supported polytetrafluoroethylene-fabric roof of the 55,000-seat stadium has been deflated and will be transported to Minnesota, US, for cleaning and recycling to be used for gym floor covers and ice rink liners.
The new cable-supported roof will be one of the largest of its type in the world after completion. A massive primary crane will be needed to carry out the project. A central tower will be constructed at the center field, with a pair of mast linked on either side of the stadium. Around the circumference of the building, thirty-six girders will be erected, which will act as a stabilizing ring before the setting up of 36 masts which are 14 stories tall. The construction will be complete with a complex web of 35 kilometers of steel cables.
The number of event days in the stadium every year will also be increased with the construction of new roof. It is expected to increase from 210 at present to about 240. The retractable roof will also keep the stadium cool which will help in hosting more events between June and August.
