30% Efficiency Gain on Football Stadium Construction
Arena Amazônia offers seats for 44,500 football fans. The Amazon Rainforest, which surrounds Manaus, and straw baskets of indigenous peoples inspired the German Gerkan, Marg und Partner (GMP) to create the architecture that Martifer Construções successfully realized.
To build the innovative steel structures of the stadium on time for the games, Martifer Construções chose Tekla software for modeling and creating assembly and general arrangement drawings. Tekla offered Martifer what they needed, including meeting the requirements for tracking materials and guaranteeing the implementation of the project within the tight deadline.
Twisted, challenging structures
A steel structure circulates the arena creating a 23,000 square meter roof. Using 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 which is essential in the tropical climate. At Martifer, 50 employees worked on design, modeling and construction management, and approximately 520 on the construction site.
In the Arena Amazônia, Martifer used Tekla solutions first for the design of the final shape of the structural beams and later for validation. One of the biggest challenges in the project was fabrication of the twisted and cambered beams which required exact coordinates control in more than twenty points. To manage pre-assembly and assembly, track materials during manufacturing and for logistics, Martifer combined the possibilities of their own and Tekla software to ensure that planning and control proceeded as they should.
BIM for collaboration and fabrication
“Our partners use Tekla solutions and we share information. Tekla was used in project coordination to clarify any questions and on-site to guide the assembly,” states Martifer´s Modeling Management Team.
Martifer has utilized Tekla for 14 years and trusted the software to successfully conclude the various phases of manufacturing. They modeled Arena Amazônia 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. They also used Tekla first to give shape to the structural beams and later validating them.
30% increase of efficiency
As Martifer utilized Tekla’s multiuser functionality they could increase efficiency by 30%.
- “We must highlight the 20% increase in productivity achieved using Tekla Structure´s Open API™ and the ability to customize reports and templates. We benefited greatly from all the time we saved and from the easiness of adapting Tekla models to the constant changes in a project of this magnitude,” says Martifer´s Modeling Management Team.
Martifer began work in November 2012 and the Arena was inaugurated in March 2014. After the games it hosts concerts and other events.
Nine other Brazilian football stadiums modeled with Tekla
Arena Amazônia is just one of the 10 world-class football stadiums in Brazil where Tekla was used for building information modeling (BIM).
To model, manufacture and assemble the new steel structure of the Arena da Baixada in Curitiba, Brazil, Brafer Construções Metálicas S/A chose Tekla. Renovated and expanded stadium hosts four football 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 meters high and 4.5 meters wide trusses that span the entire width of the stadium. To overcome the challenges, Brafer relied on Tekla´s software, which allowed them to model and detail faster the steel structure and thus save time and consequently also money. In addition Brafer used Tekla BIMsight to share information and integrate the entire production and assembly process.
