Arena Amazônia in Manaus, Brazil offers seats for 44,500 football fans in this summer’s championships. The straw baskets of native people inspired the German Gerkan, Marg und Partner (GMP) to create the architecture that Martifer Construções successfully built. With clever use of Tekla’s BIM software, Martifer Construções improved productivity by 20% and efficiency by 30%, while successfully meeting the tight construction deadlines.
A steel structure circles the stadium creating a 23,000 square meter roof. Built of 7,000 tons of steel, the main and secondary structures of angled and H profiles and steel plates rise to the 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. 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.
Martifer´s modeling management team, modeled the Arena Amazônia in 3D and extracted 2D drawings, CNC and material listings. They 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, their team first used Tekla to give shape to the structural beams and later for validating them. Arena Amazônia is just one of the 10 football stadiums in Brazil where Tekla was used for building information modeling (BIM).
