From December 9 to 10, 2017, the Second "BIM-based Prefabricated Building System Application Technology" Summit Forum was successfully held in Dongguan, Guangdong. This summit forum was hosted by the China Academy of Building Research and the 13th Five-Year National Key R&D Program "BIM-based Prefabricated Building System Application Technology" Project Department, and organized by China Construction Steel Structure Co., Ltd., China Construction Science & Technology Group Co., Ltd., Beijing Construction Technology Co., Ltd., and Jianyan Technology Co., Ltd. The forum also received co-organization and strong support from the New Building Industrialization Integrated Construction Engineering Technology Research Center of the Ministry of Housing and Urban-Rural Development, the Computer Application Branch of the China Civil Engineering Society, and the Building Structure Branch of the Architectural Society of China. The theme of this summit forum was centered on the 13th Five-Year National Key R&D Program project "BIM-based Prefabricated Building System Application Technology," focusing on the production phase of prefabricated buildings, and conducting summit forums, academic salons, and prefabricated factory visits.
　　Wang Jianqing, Director of the Comprehensive Division of the Department of Building Energy Conservation and Science & Technology of the Ministry of Housing and Urban-Rural Development, Wang Jun, President of the China Academy of Building Research, Xu Jiefeng, Vice President, Ye Haowen, Chairman of China Construction Science & Technology Group Co., Ltd., Dai Lixian, Chief Engineer of China Construction Steel Structure Co., Ltd., Jin Rui, Chief Engineer of Zhejiang Construction Engineering Group Co., Ltd., Wang Cuikun, President of Jianyan Technology Co., Ltd., Ma Encheng, Vice President, and more than 200 representatives from prefabricated building design, production, construction, scientific research and other related units, universities, and relevant government departments across the country attended the forum. 　　President Wang Jun of the China Academy of Building Research delivered a welcome speech on behalf of the forum organizers. President Wang stated: Vigorously developing building industrialization is of great significance to promoting the upgrading of the construction industry. Using BIM technology to achieve refined and efficient information management throughout the entire process of prefabricated buildings will be an inevitable trend in the development of the construction industry. As the largest comprehensive research and development institution in the national construction industry, the China Academy of Building Research has always been committed to solving key technical problems in engineering construction, and has developed an independent PKPM-BIM platform and full-process application software that conform to the characteristics of China's construction industry, establishing a Chinese BIM ecosystem and achieving good application results. In the future, PKPM will also integrate new technologies such as cloud services, big data, the Internet of Things, and artificial intelligence, develop towards intelligence and ecology, provide overall solutions for smart buildings and smart cities, and provide scientific and technological leadership and technical support for the transformation and upgrading of the construction industry. President Wang pointed out that the focus of this forum is on the production phase of prefabricated buildings, with emphasis on discussing computer-aided processing technology and production management systems for prefabricated building components. He hoped that the guests would speak freely and contribute ideas and strength to promote the development of prefabricated buildings. 　　Wang Jianqing, Director of the Comprehensive Division of the Department of Building Energy Conservation and Science & Technology of the Ministry of Housing and Urban-Rural Development, combined with the report of the 19th National Congress, gave an invited report around the theme of the forum, introducing the practical significance, existing problems, and expectations of combining BIM technology with prefabricated buildings. Director Wang pointed out that the Second Summit Forum was carried out around the National 13th Five-Year Key R&D Program "BIM-based Prefabricated Building System Application Technology" project. The project requires completing a BIM platform for prefabricated building systems with independent intellectual property rights, solving key problems in collaborative work in the design, production, transportation, and construction of prefabricated buildings, and providing scientific and technological leadership and technical support for building industrialization. Finally, he hoped that everyone would work together to improve the level of building industrialization and help the construction industry achieve green, healthy, and sustainable development. 　　Project leader Vice President Xu Jiefeng, together with the leaders of each sub-project, introduced in detail the research background, research objectives, and expected results of the project, and elaborated on the key technologies and system solutions for BIM application in the entire industry chain of prefabricated buildings. The leaders of each sub-project reported on the research progress and phased results of the five sub-projects: BIM platform, design system, production management system, construction and installation, and information management.
　　In the group photo of the 13th Five-Year Project and sub-project leaders, Chairman Ye Haowen of China Construction Science & Technology Co., Ltd. gave a speech titled "Experience and Inspiration from the Development of Prefabricated Buildings in Europe," introducing the investigation and research results of prefabricated building design, production, assembly, and information management in Europe. Around the aspects of prefabricated building design, component production, assembly construction, information application, component connectors, general contracting management, full industry chain linkage, and passive practice projects, he comprehensively displayed 9 factories, 3 software companies, 2 general contracting companies, 1 consulting design company, 4 projects, 2 associations, and the BIBM exhibition in Germany, Austria, and Spain.
　　This summit forum invited more than ten experts to give wonderful keynote reports on their respective research fields, including: Chief Engineer Dai Lixian of China Construction Steel Structure Co., Ltd. with the report titled "Sharing of Informatization in Steel Structure Building Production Management," Chief Engineer Jin Rui of Zhejiang Construction Engineering Group Co., Ltd. with the report titled "Research and Practice on Key Technologies in the Construction Process of Prefabricated Buildings Based on BIM and IoT," Vice General Manager Xia Xuyong of Beijing Construction Technology Co., Ltd. with the report titled "Prefabricated Building Design Software Based on BIM Technology and Application Examples," Researcher Tan Ping of the Engineering Earthquake Resistance Research Center of Guangzhou University with the report titled "Key Technologies for Seismic Isolation and Energy Dissipation of Industrialized Buildings," etc.
　　After the report meeting, an exchange salon on "Application of BIM-based PC Component Production Management Informatization Technology" was held. The on-site discussion atmosphere was warm, and the participating representatives conducted in-depth discussions and sharing on issues of concern and experiences in actual projects and management.
　　On the morning of December 10, the participating representatives went to the China Construction Science & Technology Dongguan Component Factory for an on-site visit to the prefabricated factory, inspected the actual application of the BIM-based production management system, and discussed and exchanged with on-site technical personnel.
　　This forum focused on the production phase of prefabricated buildings, pushing the construction of a BIM-based integrated application system for the entire process of prefabricated buildings forward a solid step. In the future, the project department will organize two summit forums each year, continuously update project research results and demonstration projects, and invite industry experts and leading enterprises to jointly plan the development of prefabricated buildings.
