Arena Amaznia offered seats for more than 40,000 soccer fans in this summers 2014 FIFA World Cup. The Amazon surrounding Manaus and straw baskets of native peoples inspired von Gerkan, Marg and Partners Architects (gmp) to create the architecture that Martifer Construes successfully built.

To build the innovative steel structures on time for the games, Martifer Construes chose Tekla software. Tekla offered Martifer what they needed and met the requirements for tracking materials and guaranteeing the implementation of the project within the tight deadline.

Twisted structures

A steel structure circles the stadium creating a 23,000-square-meter roof. The main and secondary structures of angled and H profiles and steel plates rise to a height of 31 meters. The pitch is surrounded by the steel structure coated with translucent white PTFE membrane sheets, reducing the temperature in the stadium. At Martifer, 50 employees worked on design, modeling, and construction management, and approximately 520 workers on the construction site of Arena Amaznia.

Fabricating the twisted and cambered beam that required exact coordinate control was a challenge. To manage pre-assembly and assembly, track materials during manufacturing and also for logistics, Martifer combined the possibilities of their own and Tekla software to ensure that planning and control advanced as they should.

Collaboration for efficiency

Our partners use Tekla solutions and we share information. Tekla was used in project coordination to clarify any questions and onsite to guide the assembly, said Martifers Modeling Management Team.

Martifer, which has used Tekla for 14 years, trusted the software to successfully follow through the various phases of manufacturing. They modeled the Arena Amaznia in 3D and extracted 2D drawings plus CNC and material listings, and created specific files to control geometric coordinates of the beams during manufacturing, pre-assembly, and final assembly in stages with dead, partial, and final loads. Additionally, they first used Tekla to give shape to the structural beams and later for validating these.

As Martifer utilized Teklas multiuser functionality, they could increase efficiency by 30 percent. We must highlight the 20-percent increase in productivity achieved using Tekla Structures Open API and the capability to customize reports and templates. We benefited greatly from all the time we saved and from the ease of adapting Tekla models to the constant changes in a project of this magnitude, said Martifers Modeling Management Team.

Martifer began work in November 2012 and the Arena was inaugurated in March 2014.

Arena Amaznia is just one of the 10 world-class soccer stadiums in Brazil where Tekla was used for Building Information Modeling. To model, manufacture, and assemble the new steel structure of the Arena da Baixada in Curitiba, Brazil, Brafer Construes Metlicas S/A chose Tekla. The renovated and expanded stadium hosted four soccer games in summer 2014. With 41,000 seats, the stadium now meets all international standards for quality, comfort and safety.

The challenges in the project included the 200-meter-long, free-spanning structure and the tight schedule. Brafer used 4,500 tons of steel for the roof, which has 10-meter-high and 4.5-meter-wide trusses that span the entire width of the stadium. To overcome the challenges, Brafer relied on Teklas software, which allowed them to model and detail faster the steel structure and thus save time and money. In addition, Brafer used Tekla BIMsight to share information and integrate the entire production and assembly process.
