Construction of the pavilion began with creating the frames for the structure using a CNC router. Once each panel piece was cut, the edges were sanded to prevent tearing of the fabric that would cover a portion of the pieces. Using the digital map of the pavilion, the pieces were then arranged into their proper order.
The first prototype model was created using laser-cut corrugated plastic and zip ties. The design was based on individual design explorations and team discussions. Software Rhino and Grasshopper were used to create a voronoi pattern that was pulled from the concept. Once the model was assembled, it was suspended from the workspace ceiling and shaped by the team. The design of this model’s cells proved to be ineffective to continue to full scale due to the amount of tension exerted on the shape of the cell which led to deformation. The shortcomings of this model greatly influenced the design of the subsequent models. Our second model was a simplified version of the first prototype design. The individual cells have been simplified and better highlight the organic nature of the voronoi pattern. The number of cells was reduced from the first model which allowed these pieces have better flexibility for creating the overall shape. This design approach became the base for the final, full scale pavilion design. As with the first model, this version was hung from the ceiling and then allowed to form naturally under the influence of gravity with a few minor tweaks once everything was in place. MDF and zip ties were used to create this model at both quarter scale and half scale. The full scale pavilion's base structure was influenced heavily from the successes of this version.
TESSELLATIONS AND WEAVING
Exploration into the incorporation of weaving elements into the pavilion design started from the initial design phase. The purpose of the weaving was to add interest to the aesthetic of the pavilion. The weaving also offered an opportunity to provide an added dimension to the design and further reflect the concept driving the entire design. Although a weaving strategy was not utilized in the design of the pavilion, several mockups and strategies were explored.
The tessellations serve as an important design component for the pavilion. The base structure for the pavilion had been designed to accommodate these extruded pieces. Much like the intent behind the weaving, the tessellations serve to better reflect the concept of the pavilion and provide dimension for the structure. Many versions of tessellation possibilities were tested during the design process in both small scale models and the prototype models.
