WISDRI has innovatively created the "Integrated Design" concept, which is based on sponge city, utility tunnel, underground space, street landscape and road traffic network. The application of this concept makes once-for-all municipal infrastructure design and construction a reality, thus avoiding repeated excavation and saving construction investment. In this way, a perfect planning can be achieved. WISDRI has completed several urban integrated design projects such as Central City of Wuhan Optics Valley, etc. Through application and promotion of this concept, The level of urban construction level will be greatly improved through application and promotion of this concept. This "Integrated Design" concept represents the development trend of urban construction design industry.
