Estadio Nacional

Estádio Nacional, originally built in 1974 and located in Brazil’s capital, underwent a major reconstruction for the 2014 World Cup – expanding its capacity from 42,200 to 70,042 to host seven World Cup matches. Birdair fabricated and supplied the PTFE fiberglass membrane, clamping and hardware for the facility. The consortium Taiyo Birdair do Brasil – Entap – Protende was responsible for installing the entire roof’s steel and cable structure, including the PTFE outer roof and liner membrane. The project involved building a new lower tier and retaining the upper tier with the addition of a new 920,000-square-foot double-layer suspended tensile roof.
