I've been there together with IBERIA747 one week ago, and I have to say: It's looking absolutely great. Specially when you are coming closer than you see how large the terminals are in real. You can see them sometimes in the background of Madrid-Barajas pictures in the DB
. Notice that there are three or four floors under the surface.
And what IBERIA747 already wrote: A lot of construction still must be done for the access/exit roads for the passengers and airline/terminal employees.
Another strange thing they didn't think about is an extension of the subway. it now stops in Barajas. You can see the terminals but it is still a very long walk. There is a subway connection between both new terminals, but no connection to downtown Madrid and the old terminals. I think this will be a big problem for transfer passengers from intercontinental flights when they arrive in the actual terminal one. This terminal and the two new ones are the most far away from each other. Hopefully everything is solved and cleared before the new terminals are opened otherwise they will have a lot of start-up problems.
Oh almost forgotten: They have also forgotten a good viewing area for the increasing number of aircraft spotters/photographers around the globe. But unfortunately that's common in new terminal/airport designs.
