Dubai Int. development design, a must see!

Found some interesting pics of a model of the future design of DIA. This model was at the Dubai Int. Airshow and shows concourse’s 2 and 3. If you look into the model a bit you can see the areas where the entire arrivals and departures levels will be situated, strait under the tarmac! As an aspiring architect, i am absolutely amazed by this design… Any more information on the airport and the architects that designed it would be much appreciated.
