Dave Hugo, the city council's 2010 technical director, said everything was going well, with 72 trusses already in place to support the roof.
The glass structure, made of laminated sheets 16mm thick, will weigh 1 500 tons and fill an area of 37sq km.
Engineers hope to finished with the roof construction in September.
"No other stadiums (in the world) are using glass, they use other materials," said Hugo.
...The whole roof construction is expected to cost about R475-million.
