Double-Layered Diagrid Facade Structure
Centre for Advanced Wood Processing, UBC Vancouver

Role: Development, planning, execution; in a research team

Research Associate Oliver David Krieg of the Institute for Computational Design and Construction (ICD), and Assistant Professor David Correa from University of Waterloo held a workshop on robotic fabrication at the Centre for Advanced Wood Processing of the University of British Columbia, Vancouver, from September 9th to 13th 2017.
Using a state of the art eight axis industrial robot configuration, the workshop guided participants through the unique technical and conceptual foundations that underpin robotic milling in wood through the development of a full-scale fabrication project.

While many industries have made leaps and bounds in adopting highly flexible and fully automated fabrication workflows using robotics, the construction and design industry are only just starting to open the door to these technologies. Recent developments in robotics combined with more accessible design-to-fabrication tools can now offer architects, designers and fabricators unprecedented access to a new design paradigm.

By using advanced timber fabrication techniques and taking full advantage of the extended fabrication range of the multi-axis set up, large sections of plywood were custom milled and assembled on-site into a unique one-to-one scale architectural prototype. The prefabricated elements serve as a diagrid sub-structure for off-the-shelf façade planks. Once assembled, they form a stable, doubly-curved building system. The prototype showcases distinctive wood fabrication possibilities that integrate computational design, material characteristics, and digital fabrication in a direct design to production paradigm. Taking a double-curved design surface as an input, the tool generates a buildable structure within the material and machine constraints. A simulation of the robotic milling process and export of robot control files are fully integrated in the computational design process. It allowed to form a digital loop between design and fabrication leading not only to innovation in timber construction, but also for a re-interpretation of wood architecture.
