Soomeen Hahm, Igor Pantic, Wenqian Yang completed a small installation from PVC pipe components during the AA Visiting School in Shanghai. The simplicity of the kit of parts ensured precision of joints in the structure, and allowed a holographic model to be used to maximise the complexity of the design. By using a holographic model to show lengths of pipe required as well as the location of joint components, the fabricators could rapidly assemble the structure from simple hand tools and work with tolerances in overlap between pipe and socket to maintain precise alignment with the digital model.
