The Beira-Rio Stadium in Porto Alegre, Brazil was renovated by the Santini & Rocha Arquitetos practice for the 2014 FIFA World Cup which begins in 12 June and it brings the stadium to contemporary standards with the addition of a roof and a modernized infrastructure.
The stadium was originally built in 1969 as the home of the S. C. Internacional football club and it was under renovations before the Santini & Rocha Arquitetos began to oversee the project. The concrete lower tiers were removed to leave room for the new VIP facilities and the electronic infrastructure was updated as well as the plumbing.
The previous solid roof was replaced with ramps and turnstile areas and a PTFE membrane allows the sunlight to filter to the stands, reducing the absorption of heat. The roof is also self-cleaning and it channels rainwater to tanks that store it for the toilets, reducing the water consumption.
The stadium was extended with 70 suites, a museum, media room, shops and 14 towers linking the different floors to allow the stadium evacuation in eight minutes.
