CUHK Humanitarian Architecture Wins Accolade

CUHK Bridge Project Wins Jury’s Award of Sustainable Achievement at RICS Awards China 2019 

The 21-metre ‘Yi Xin Qiao’ (the bridge of comradeship) in Dujia Village, Chongqing, is the longest bamboo bridge in rural China.


The ‘Yi Xin Qiao’ bridge project in Dujia Village, Chongqing, has been awarded the Jury’s Award of Sustainability Achievement at the Royal Institution of Chartered Surveyors (RICS) Awards China 2019. This collaboration project between The Chinese University of Hong Kong (CUHK) and three other universities in China was recognised for its outstanding ideas in bamboo research and the achievement in promoting rural sustainability. 

Bamboo is the most environmentally friendly building material known to the public. With years of studies and experiments, the CUHK team has made breakthrough to overcome the technical constraints of bamboo and improve its fragility, durability and structural integrity. This world leading effort will greatly promote the use of bamboo in the architectural sector. 

The ‘Yi Xin Qiao’ project, fully sponsored by the Chan Cheung Man Chung Charitable Foundation, is part of the ‘One University One Village Rural Sustainable Development Assistance Programme’ (1U1V) initiated by CUHK researchers to extend modern bamboo application and to promote sustainable architecture and development. 

The ‘Yi Xin Qiao’ bridge measures 21 metres long and 3 metres wide, with a usable surface of two metres wide. Constructed with 700 moso bamboos, the bridge is the longest among modern bamboo bridges in rural China. This bamboo bridge design can theoretically be applied to most impoverished villages in China and eliminate the dangers in river-crossing. This makes it more convenient for villagers to travel around and improves their livelihood. 

The bridge project’s innovative ideas and commitment in environmental protection and sustainable development have won it and its research team numerous accolades in China, including the First Prize at 2017 College Student Bridge Design Competition, and the Special Contribution Award for Bamboo Architecture at the first Global Bamboo and Rattan Congress. These awards recognise the contributions of the project and encourage the 1U1V team to continue implementing and promoting modern bamboo building in rural China.  

Using the research results and practice, the 1U1V team has also been trying to apply bamboo materials to rooftop structural architecture and an anti-seismic bamboo structural village house. Examples include the bamboo rooftop structure for the 1U1V Earth Building Research Centre in Kunming and the bamboo truss arch structure for the INBAR Pavilion located in the International Horticultural Exhibition 2019, Beijing, which was known as the ‘Bamboo Eye’ of the exhibition.  

The team will further study the key technologies of design and construction of long-span bamboo structures, improve their durability, and make modern bamboo structures more widely used in rural construction, urban public buildings and beyond. The hope is that one day sustainable bamboo architecture can be promoted worldwide.
