The ‘big lift’ of a state-of-the-art roof at Khalifa International Stadium in Qatar has been completed, according to Fifa, football’s global governing body.
Work on the roof membrane is currently ongoing and will continue until early January, with the renovation project set to be wrapped up in the first quarter of next year, making the stadium the first of the 2022 World Cup host venues to be finished ahead of the tournament.
The innovative new roof will provide more shade to the stands and pitch, while also letting enough sunlight through to the turf for natural growth of the grass.
The main components of the roof membrane are manufactured in Japan and the US respectively. A 44,000-square-metre membrane made of two materials is being used to achieve Fifa requirements regarding sunlight over the pitch.
A net of German and Italian-made steel tension cables weighing 4,000 tonnes has been put up to hold the 92 panels that will make up the roof. Both ETFE and PTFE panels were shipped from Japan and the US to Mexico for cutting and welding patterns.
After the renovation, the stadium will seat more than 40,000 spectators and will retain cooling technology on the field, in the stands and in the concourses.
