Sochi is going to host the Olympics 2014. Some contests are going to be held in the mountains in the Krasnaya Polyana area.
One of the hotel complexes in Krasnaya Polyana.
Right now, they are building a road and a railroad connecting Krasnaya Polyana and Adler. Part of the road which is planned to be wider than the exisiting one is going to run along the Mzymty River.
In some places, the road will lay across tunnels featuring a total length of 30 km.
Not far from Adler is Vesely Village where they produce tunnel tubings. The plant consists of several large rooms where they produce and store their produce. To make tubings, they need concrete and iron rods.

They have equipped the room with motion detectors to protect workers from possible accidents.
Most operations are automated
