Either I was on the same tour as Hatman or Friday was tour day at the Airport. My pictures are pretty similar.
Additional info I learned:
-North Concourse new opening date is Oct. 27, 2020 so a little over a month after the rest of the terminal is opened.
-The old garage will not be imploded. It will have to be taken down traditionally. They expect it to take 2-3 months then they can start stone column installation and move forward with south-east terminal.
-As Hatman said, the Baggage conveyor system is quite the site. On level 1, there are 14 carousels for the baggage handlers to drive up to load bags for flights. This will handle all the luggage at opening day.
-Once the central tunnel is completed, baggage conveyors will send luggage out to the north concourse and handled separately.
-The air handling in the airport is interesting. Rather than having tons of air ducts in the ceiling and having to heat/cool the whole space, you will notice air vents in each of the columns and along walls which will put out hot/cold air. They are only concerned with keeping the bottom 12' of the building comfortable. Air returns are located in the ceiling. This will help in their quest for Leed Gold.
