NBBJ, in partnership with CCDI, designed the Hangzhou Sports Park on a 400,000-square-meter site on the Qian Tang riverfront opposite the city’s new Central Business District. The main stadium broke ground in 2011 and is slated for completion in 2017.

As worldwide demand for steel increases — by 78% in the last decade alone — so does the cost, which has skyrocketed 217% since 2007. That’s why we use parametric design to cut waste while creating functionality and form.

Our designers leveraged advanced parametric scripts and modeling techniques to develop and optimize the exterior shell of the Hangzhou stadium. The steel shell and concrete bowl systems were coordinated and linked for stability and optimized steel use. Because the model was parametric, design changes could be made with an extremely short turnaround, eliminating the “build-test-discard” method common in traditional modeling.

The parametric model was used as the basis for cross-disciplinary collaboration with engineers and material consultants. The engineers and consultants could use the design team’s output directly for performing their specialized design and analysis operations. The close communication between disciplines enabled the design team to ensure quality control and also find opportunities for further optimization.

The end result? We achieved a 67% steel savings over similar arenas like the famed Bird’s Nest, the Beijing National Stadium.

Grasshopper is a visual programming language and environment that pairs with Rhino 3D, a software program also developed by Robert McNeel & Associates. Grasshopper allows users to build algorithms by dragging and connecting components on a digital canvas. From parametric modeling and fabrication, lighting performance analysis, to building energy consumption, Grasshopper provides an intuitive way to explore design without requiring programming experience.

Rhinoceros 3D is a 3D computer graphics and computer-aided design application software developed by the American company Robert McNeel & Associates. Utilizing NURBS mathematical modeling to produce precise representations of free-form, curving surfaces, Rhino is used in industries such as architecture, industrial design, automotive design, product design, and multimedia and graphic design.

Tennis Court is displaced on the roof of Iran-mall project located in Tehran, Iran. The project was under progression when we got invited to work on. Ali Karimbeigi Darian was the main façade consultant and Pars-Goofca had taken on the contractor responsibility. Ardaena team was asked to manage the algorithmic shop drawing of the façade structure double curved belts. The images below show the sine based curves of the façade. We were in charge of using Grasshopper3D to produce prefabrication documents in correspondence to tiny changes but automatically matched.
