In the month of August, the work for assembling the rooftop cover at the Castelão starts a new stage. Around 70% of the trellised scissor beams have been put up in the stadium in Fortaleza (capital of the state of Ceará, in Brazil's northeast region). After the 60 support beams were put up, parts of the new structure are being assembled – each weighing 28 tons. Over 83% of the stadium’s project has been concluded. The venue’s delivery date has been set for December 2012.
In the next few days, the rooftop cover will have its metal sandwich tiles put up, made up of two metal sides and filled with insulating foam. According to the consortium in charge, made up by the Galvão Engenharia and Andrande Medonça construction companies, approximately 20% of the rooftop cover will be made of polycarbonate to supply ideal shade for improving television broadcast, as well as isolating the pitch.
The project of the rooftop cover was designed with the aim of ensuring comfort to those in the audience and reaches 100% of the covered seats. In order to ensure the structure’s safety, in July 2014 the project was put through trials by the Technology Research Institute (IPT) in Sao Paulo, where the impact of the wind on the rooftop cover was measured.
