INTERNATIONAL GUI’AN INNOVATION PARK, GUIZHOU GUI’AN INNOVATION PARK, GUIZHOU Wilder Associates’ Gui’an Innovation Park in Guizhou, China, dubbed a ‘Sponge City’, demonstrates new approaches to surface water management. ALESSANDRO CARRARA spoke with director Peter Wilder to find out more about this project and how it has improved the local area T that prevent runoff from roads entering into the watercourse. What would you say was your main goal with the landscape scheme? Our main goal was to integrate the remnants of tea plantation terraces into the masterplan so that the historic landform could be preserved as a reminder of its past use. We integrated them as a series of bio-filtration regimes Do you think you achieved your main goal? In terms of the design of the water management system I would say yes we did. But in terms of achieving a platform for research, development and innovation I would say not really. However, from our perspective the most important thing was to build a sponge city, a site that behaves very much like a sponge that absorbs water runoff and treated water run off. Part of the reason why this site was chosen is that it took on a limestone cast geology. What that means is that any water that falls on the ground goes straight into the water aquifer. So if it gets polluted ell me about the brief for the project? Our brief was to develop a model for a Sponge City that would serve as an exemplar for other designers to follow. The park should also be an exemplar for sustainable construction, energy waster and surface water treatment along with the integration of local skills and crafts into the park. it will take that pollutant right into the drinking water effectively. So we had to demonstrate that even on a difficult site like that, we could achieve a system that filtered and cleaned up the surface water run-off before it got into the ground. How were you commissioned to work on the project? We were originally brought in as environmental consultants to the Building Research Establishment (BRE) but were retained as part of the design team to take the scheme forward to construction. Who was the client and how was it working with them? Our client was BRE China but our ultimate client was the mayor of Gui’an November 2018 | Landscape Insight 27
