After some delays in the project, construction on the woven bamboocrete “Ghosla” (nest) roof has finally begun. The video below shows how the weaving process enables a team of traditional bamboo craftsmen to easily construct the digitally form-found, double-curved, funicular shell using only linear measurements read out to them by the contractor. The drawing provided by Kamath Design Studio to the contractor is a plan consisting of linear dimensions along each bamboo member where that member intersects other members. The drawing also communicates the weaving scheme, that is, whether a member goes above or below another member when they intersect. Our studio provided the height above ground at each intersection to verify that the bamboo members are curving as desired, and that the shape of the shell conforms to the digitally form-found funicular shape.
While a 1:50 scale construction model of this roof had been built using the same drawing set to test the concept of weaving a complex curved surface using only linear dimensional information, the idea was so far untested at full scale.
I had outlined the concept of using weaving to build complex digitally modeled surfaces using manual methods of construction in this earlier post.
