Evaluation & Design Workflow

Finally, suggested systems were evaluated based on visual elegance, the possibility of fabrication and assembly, structural performance, durability, and cost. Other considered factors were the usage of systems for 3 layer or 2 layer structures, needing to construct a CNC rotary system, and facilities provided in DC House Fab

Lab. Considering these criteria, alternative RAdial was chosen. we developed a “digital design workflow” in a parametric modeling platform known as “grasshopper”. This digital workflow fully automates the modeling process and delivers the required outputs in a timely manner.

BIM Model & Prototyping

Finally, The second output is the shop drawing of the nodes and handles. These parts will be milled from plywood sheets with a 3 Axis CNC machine. The final output is the numerical statistics about the BIM model, such as element count and length.

Custom Digital Fabrication Tools

For the bamboo poles, we understood they would need four bolts at each end and not aligned to one another to connect to their respective joints. A rotary axis was not affordable and might not fit our CNC bed. we had to design a custom one.

Fabrication Process And Assembly

Bamboos that had thicker mantle and were larger in diameter were placed on the basement structure using screw. Middle structures of basements which were similar to six-winged stars were then added and fixed to the bamboos of basements at the top. The three basements of the structure started to be constructed at the same time until they met each other in the middle.
