Qatar’s Supreme Committee for Delivery & Legacy has appointed the US-based Aecom as project manager and Denmark’s Ramboll as design consultant for the Al-Rayyan stadium scheme.

The stadium will seat about 40,000 people during the football World Cup in 2022. Following the tournament, the stadium’s modular top tier will be disassembled and used to build football facilities in developing countries that lack sporting infrastructure, in coordination with football’s governing body, Fifa.

The stadium will also contain an open-air, natural grass pitch that can be cooled to 26 degrees Celsius, with shaded spectator stands that can be cooled to between 24 and 28 degrees Celsius.

In May 2013, Aecom was appointed design consultant and the local office of Kuwait-based KEO Consultants as project manager for the Al-Wakrah stadium project.

Doha expects to spend $4bn on building stadiums and related sporting infrastructure for the World Cup. The largest new stadium planned is the Lusail Iconic stadium, which will have a capacity of more than 86,000 people and is to be used for the opening match and the final.

“We are rapidly making progress and are well on schedule to deliver all stadiums long before fans arrive for the 2022 Fifa World Cup,” said Hassan al-Thawadi, secretary-general of the Supreme Committee for Delivery & Legacy. “We are looking forward to working with our partners on Al-Rayyan stadium to build an amazing sporting facility that serves the local community.”

The committee also said all contracts on Al-Rayyan stadium will incorporate its new standards governing the welfare of workers. “Contractual enforcement of these standards and a rigorous four-tier auditing system will guarantee international best practice on Al-Rayyan stadium and all venue and accommodation sites,” a statement from the committee said.

Qatar has received a barrage of criticism in recent months pertaining to concerns about holding the games in the searing heat and about the working conditions faced by labourers building the World Cup stadiums.
