Discovery Channel is running a series on the world cup stadiums. Currently watching the Maracana episode. Interesting stuff how they have redeveloped the stadium, albeit not very much of the old structure was actually retained.

Overall I'm happy I never watched football there prior to its redevelopment - because the concrete roof was absolutely f***ed.

Falling apart f***ed?

This.

The roof structure had to be expanded to increase spectator coverage from 40% to 95%+. Plan A was to secure a tarp roof to the existing reinforced concrete roof. When they stripped back they essentially discovered not only would the roof not support the extra weight, it was a miracle it was still standing.

I'm filling in a few gaps with my own from here. The reinforced concrete is essentially designed that the steel inside the concrete provides its flexing strength, which concrete has f**k all of. It would last forever if you kept it dry, which it wasn't. As the water penetrates the concrete and gets to the steel it causes it to rust inside. The two big problems there is the flexing strength is lost, but also the metal expands when it rusts which causes the concrete to crack. So, combine 1) concrete roof that weighs thousands of tonnes, 2) No flexing strength, 3) cracking 4) 80,000 people underneath who rock so hard that they caused the Gabba to wobble during the Olympics.

Not going there = bullet dodged.

All good now, it's just a bed sheet hanging over the top, and only the upper bowl and supporting floors were retained, the lower bowl is new.

Also just quietly, f**k the Maracana and the completed Waverley design look similar.

Jesus they got lucky.

The locals can rightly protest a lot about the world cup, but I'd say the price to redo this stadium prooooobably was a wash at worst.

Far cheaper to demolish or build new on a greenfield. However the stadium was protected in legislation as a site of national significance. Why you'd want to preserve a building you lost to Uruguay in is beyond me.

Ten days to go to its first game and the stadium in Curitiba is still not finished.
