Impressions from last week’s crit with Professor Kaufmann

1:20 sections of all four different rooms (class room, cafeteria, niche and the library with the teachers’ office) were elaborated and with it the details of the roof and loadbearing structure. Professor Kaufmann provides valuable feedback on a the bamboo rafter above the class rooms.

Depending on the availability of the bamboo, the rafter will be composed of three culms of approximately 80 millimeters in diameter each, that will be joined by steel pins. The holes for the pins should ideally be cut next to the diaphragms naturally found in bamboo as the fibre is stronger here and is less likely to split as a result of sheering loads.

Bamboo needs to be treated with acid in order to withstand natural enemies insects, fungi or microorganisms. Untreated bamboo rarely lasts longer than 5 years and thus becomes inviable as a building material for a permanent structure.
