Materials are being temporarily stored just west of the main terminal building. The required rotating tower cranes are also being installed there. The auxiliary framework being set up on the roof of the second level gives an impression of how high the future check-in hall will be. Eighteen-meter-tall steel towers loom over the building’s future check-in area. Construction workers are assembling the parts of a roof section on them. For each one, steel elements are assembled into a kind of three-dimensional framework roughly 4.5 meters tall. First, workers connect the steel supporting structures and seal the sections at the top. To eliminate the need for suspended work platforms at a later stage, they integrate required equipment and features during this stage of the work, including cable conduits, sprinklers, and the ventilation system. Finally, they attach a grated platform for subsequent maintenance work.
