One of the world’s most famous football venues is entering a historical phase. First time ever all of the audience will be covered. That is, of course, once the roof is in place. So far the most impressive stage of construction works is to begin with lifting of the giant web that will support membrane sheet.

All of the steel cables are already laid on the stands awaiting for works to begin. The ‘big lift’ is expected to last until end of November, when the structure should be placed 40 meters above the pitch.

Behind pitch corners four massive scaffoldings have been erected. Those will support gangways for technicians hanged under the future roof. Those will be used to provide access to artificial lighting, sound system and giant screens.

After the lift is complete, steel elements will be placed onto the steel cables. Final stage will be covering the whole web with fiberglass membrane, Teflon coated. With radius of 68 meters, the membrane surface will be among world’s largest.

Yesterday training for 25 alpinists ended. Only 8 of them are professionals, while 17 other are volunteer workers who agreed to carry out tasks up to 40 meters above the ground.
