Here's a pic Face81 took yesterday. The angle of this shot is great because we see both sides of the concourse.
If you look at the pics from the beginning of April we can notice there has been significant progress. The closer side of the concourse has two additional aluminum sections done, and the farther end has added two sections of glass. With this speed we should see the cladding of the concourse complete before the end of the year.
Construction might slow down in the hot summer months, and Ramadan just a little bit. Don't forget this is a government project that will be pushed hard for completion.
