Roof over Khalifa International Stadium nears completion

0

An innovative new roof is in the process of being installed at Khalifa International Stadium, which will provide more shade to the stands and pitch, while also letting enough sunlight through to the turf for natural growth of the grass, reports the website of the Supreme Committee for Delivery and Legacy – organizers of the Qatar 2022 FIFA World Cup.

The lifting of the roof is completed and installation of the roof membranes is currently ongoing and will continue until the early part of this month, with completion of the stadium renovation planned for the first quarter of 2017.

The main components of the roof membrane are manufactured in Japan and USA respectively. A 473,600ft2 membrane made of two materials is being used to achieve FIFA requirements regarding sunlight over the pitch on the first proposed host venue for the 2022 FIFA World Cup Qatar set for completion.

An intricate net of German and Italian-made steel tension cables weighing 4,000 tons 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 USA to Mexico for cutting and welding patterns.
