Non standard timber elements

Locally Processed Timber Planks for Free-Form Surfaces
Since the early 1980s, the financial situation of forest owners in Switzerland is generally difficult. At this time the only salable forest product no longer covers operating costs. The local wood is transported to neighboring timber industries for further processing and together with other imported timber products are transferred back as a construction material. In this context, it is worth to develop methodologies to use local forest resources for public and private buildings without importing wood as is currently done.
Thanks to new technologies like robotic fabrication, we aim to optimize and exploit the local wood resources in order to use it directly for local buildings. This project describes usage of sawn wood – timber planks for double curved surfaces. The base element in proposed structure is inspired from tradition carpentry and its wood working joints. The use of polygon mesh processing and planarization algorithms helps to discretize global surface to discrete fabrication aware elements. In addition, geometrical and anatomical constraints are taking into account when choosing type of joinery for component connection. Lastly, 5-axis CNC tool path generation is developed in order to build demonstrator.

Structure Studies

Grand Chalet Train Station

This technology is currently developped for a Train Station Project in Rossiniere. The project’s aims is to use local wood throught and innovative, economic and ecologic structure.
