China’s unequaled rate of urbanization and high population growth has helped its policy of aggressive expansion globally and nationally, aided by its ability to build cheap and quickly. But meeting the country’s construction demands has come at the cost of architectural identity, according to Philip Yuan, Founder of the firm Archi-Union Architects.
‘It’s a kind of copy and paste process,’ Yuan says of the repetitive, nondescript buildings found in Chinese cities. ‘It’s a pity, (because by) building too fast, we lose tradition and identity of what China should be.’
The Chinese architect has deviated from the copy and paste building model and instead is exploring experimental new approaches to construction. His techniques, which include the use of digital fabrication and robotics, could offer a new way to produce sophisticated buildings in shorter timeframes.
Take, for instance, ‘In Bamboo,’ a wooden pavilion conceived in collaboration with bamboo weavers in Daoming, Sichuan province. The project’s design is not only architecturally distinctive but also extraordinarily complex — and only made possible through cutting-edge technology.
Using computational design based on algorithms and a pair of robotic arms rigged to ‘cut like (the) two hands of a human being,’ the figure-eight-shaped building was completed in just 52 days. By Yuan’s estimates, it would have taken six to 12 months in China, or up to two years in the West had traditional building methods been employed.
‘Every column and every beam has a special angle and different height,’ Yuan explains. ‘If you use your hand, it’s impossible to make it in such a short (period of) time because every joint is different.’
The project exemplifies the concept of ‘digital tectonics,’ a phrase Archi-Union uses to express this new type of collaboration between human designers and machines. The term balances technologies and global methodologies with traditional cultures and local building techniques.
For ‘In Bamboo,’ separate panels and sections were fabricated off-site using local materials like timber, tiles, and bamboo. They were then transported and assembled on site, helping to reduce waste and energy costs.
In the case of another Archi-Union project, the Chi She Gallery in Shanghai, a robotic arm was used to lay an intricate, rippled brick facade to a level of precision unattainable by humans.
‘Although the material (brick) is traditional, we can organize the form into something new,’ Yuan says of the design’s abstract geometry. ‘It’s a collaboration between human and machine. I can teach the robotics, and it can place it precisely.’
