Gao Wensheng expressed gratitude for the warm reception of CCCC Fourth Harbor Design Institute and gave a detailed introduction to the history, scientific research innovation, and achievement transformation of China Academy of Building Research and Jianyan Foundation. Mai Yuxiong extended a warm welcome to Gao Wensheng and his delegation and systematically introduced the development history, business layout, and core strengths of CCCC Fourth Harbor Design Institute. CCCC Fourth Harbor Design Institute has been deeply engaged in port and waterway, urban infrastructure, underground engineering, green building, and other fields for many years, with outstanding advantages and fruitful achievements in engineering construction under complex geological conditions and the upgrading and renovation of urban infrastructure.

During the exchange session, technical personnel highlighted a number of distinctive technologies of the Institute of Foundation Engineering, covering the reinforcement and renovation of existing buildings, underground space development, optimized foundation design, foundation pit support, and green energy piles, specifically including foundation reinforcement and inclination correction technology for existing buildings, key technologies for underground space development of existing buildings in urban renewal, technology for optimizing foundation design and eliminating settlement post-cast strips in connected main building and podium structures, composite anchor and composite anchor anti-uplift pile technology, prestressed cantilever pile foundation pit support technology, energy pile technology, and large-diameter quasi-rigid cement-soil rotary mixing pile technology, comprehensively demonstrating the scientific research innovation and engineering application strength of the Institute of Foundation Engineering in the geotechnical engineering field.

The two parties conducted in-depth discussions on the engineering application scenarios, adaptability to complex working conditions, and technological iterative upgrading of the above distinctive technologies, and reached broad consensus. Both parties agreed that the two organizations are highly aligned in business and complementary in technical advantages. In the future, they can fully leverage their respective advantageous resources in scientific research, design, and engineering practice to deepen multi-dimensional collaborative innovation, jointly tackle key technical challenges in the industry, and jointly promote the geotechnical engineering field toward high-quality, green, and intelligent development.

Before the symposium, Qin Jie, Chief Engineer and Deputy General Manager of CCCC Fourth Harbor Design Institute, met with Gao Wensheng and his delegation. After the symposium, Gao Wensheng and his delegation visited the Pinzhi Exhibition Hall of CCCC Fourth Harbor Design Institute to gain an in-depth understanding of its development history, major engineering achievements, and scientific and technological innovation results through on-site observation.

Relevant responsible persons and technical personnel from the Greater Bay Area Branch and Key Account Department of Jianyan Foundation, and the Overseas Department and Urban-Rural Department of CCCC Fourth Harbor Design Institute participated in the symposium and exchange.
