Weird question: will there be a big moment when suddenly those foundations for the roof all become load-bearing, so when all the stresses and strains from the weight of the fall (hopefully!) into the right place? Or is it something that gets built up gradually? Sorry, I'm obviously crap on the technical terms of civil engineering and what not, hope you see what I mean.
When they built the roof on the San Siro in Milan for Italia 90 they showed the hoisting of one massive girder into position live on telly. This is much more important, obviously.
All concrete should reach it's design strength in 28 days (4/5 of total strength which is gained fully over years)
As for the roof, it will be supported temporarily whilst being constructed. Only when all the founds are completed will it be able to be 'released'
