The roof of Khalifa International Stadium is fast nearing completion, as part of its extensive renovation.

Khalifa Stadium is undergoing an extensive renovation to meet requirements and standards for FIFA World Cup stadiums.

The renovations include the addition of new building to the east wing, the construction of an Olympic sports museum and building a single roof to cover the entire seating area.

A state-of-the-art roof is presently being installed which will provide additional shade to the stands and pitch, while also letting in more sunlight to the turf for natural grass below.

The ‘big lift’ operation of the roof has been completed and the installation of the roof membrane is currently underway, The Peninsula reported.

This final stage of installation will continue until early January with the completed stadium renovation planned for the first quarter of 2017.

Engineer Mansoor Al Muhannadi, Khalifa International Stadium – project manager at Aspire Zone Foundation, said: “We are very pleased with the progress on site, from the exterior parts to the forthcoming installation of the new roof structure.

“It will be a proud moment for everyone in the team when the construction is completed for the first proposed host venue for the 2022 FIFA World Cup Qatar and this is what the team on site is working towards on a daily basis.”

Spanning 44,000m² and comprising two materials (ETFE and PTFE), the roof membrane is part of achieving FIFA requirements concerning sunlight over the pitch. The main components of the roof membrane are manufactured in Japan and USA respectively and were shipped to Mexico for cutting and welding patterns.

A complex net of German and Italian-made steel tension cables weighing 4,000 tonnes holds up the 92 panels that will make up the roof.

When completed, the stadium will accommodate more than 40,000 spectators and will be cooled throughout, including the field of play, all seats and concourses.

“When we did the shadow analysis we noticed a portion of the southern side of the field of play wouldn’t get any sunlight if we used only PTFE. Meanwhile, ETFE is a more transparent material that allows more than 80% of sunlight to go into the turf,” Al Muhannadi added.

With site safety a top priority across all construction activities taking place at Khalifa International Stadium and all SC programme sites, to date, more than five million man-hours have been worked on site without any lost time.

The stadium is a proposed host venue for 2022 FIFA World Cup Qatar matches through to the quarter-finals.
