First of the two double steel arches for Spanish architect/engineer Santiago Calatrava's new roof to Athens' main Olympic stadium is now taking shape.
Tubular steel sections are being erected on temporary towers alongside the 85,000 seat facility. The roof comprises a 303m wide 85m high arch straddling the stadium. This will support a lower 48m high arch with cable stays. When complete the structure will be jacked 70m into position astride the stadium. Italian steel firm Cimolai fabricated the 3.6m diameter tube sections for the roof in Italy and is now welding them into longer sections for lifting into place and final welding in the air. Greek contractor Aktor is main contractor for the project.
