Work is now under way on five 2022 Fifa World Cup venues that are in different stages of construction in Qatar, The Peninsula said in a report.
Demolition has begun on Al Rayyan Stadium that will be rebuilt to increase seating capacity from 22,000 to 40,000.
In addition, construction work is in progress at four more venues. This includes enabling works at Al Wakrah Stadium and Qatar Foundation Stadium; early works at Al Bayt Stadium in Al Khor City; and main construction works at Khalifa International Stadium, which will increase the seating capacity to 45,000.
Work on Al Wakrah and Al Bayt stadiums is set to be completed in 2018.
A joint venture between Midmac Contracting and Six Construct, a subsidiary of the Belgian Besix Group, is responsible for the work on Khalifa stadium, which includes the addition of a new roof and cooling technology.
Dar Al Handasah is the design consultant for the Khalifa stadium project, and Projacs is the project manager for Al Bayt Stadium project.
Aspire Zone Foundation is the delivery organisation of both.
Meanwhile, the Qatar Foundation Stadium at Education City is in the detailed design development stage. The main contract tendering process is currently under way and an announcement will be made upon its completion. The design consultant is RFA Fenwick, while the project management is being undertaken by Astad.
All proposed stadiums and training sites will be cooled to an optimal 26 deg C.
The cooling technology was tested this summer at cooled, open-air fan zones at Katara Beach (Doha) and at the Aspire Zone Foundation. The technology that will be in place in each of the proposed host venues will allow football to be played in comfortable conditions throughout the year in Qatar.
