Since I am working there..... So I will reply on your comments.... Actually it's not empty at all.... This photo was captured in the time range from 11 AM to 3 PM... Nobody is allowed to work in Summer from 11 AM to 3 PM inside the project..... In peak summer, the temperature will be 26 degree (Plus or minus 2 degrees).... This stadium will be the first air conditioned stadium in Qatar... Roof is extended to minimize the external heat loads and to facilitate the air conditioning system
