Before work to install the equipment can start, the huge steel frames have to reach their final positions on the roof. This is by no means light work – each of them can weigh up to 50 tonnes. A caterpillar crane heaves them up one after the other. It’s a demanding task, calling for teamwork and absolute precision. The crane operator below can’t see the loads as they come down up above, and therefore depends on instructions from a helper. They communicate by radio, making sure as a team that the frame sections are eased into place with millimeter accuracy. Other workers secure and connect them, and then apply a special coating as protection from the wind and weather. Finally, it’s time to install the actual equipment that will later ensure a comfortable stay for passengers using the new Terminal 3.
