Changzhou, Jiangsu: a major change from 'building' a house to 'building' a house

The modernization development of Changzhou's construction industry has achieved remarkable results, and completed the provincial construction one year ahead of schedule.“Thirteenth Five”Planning goals require“establish”house to“take”A major change in the house“Standardized design, factory production, prefabricated construction, finished decoration, information management”, which is the modernization of the construction industry. In recent years, Changzhou has attached great importance to the modernization development of the construction industry.“Government guidance, demonstration guidance, key breakthroughs”principle, scientifically formulate the development path, introduce policies and measures pragmatically, establish an efficient working mechanism, and solidly promote the project construction. It is reported that in 2019, the new construction area of ​​prefabricated buildings in the city reached 7.8 million square meters, accounting for 42.8% of the projects started in the same period.“Thirteenth Five”The target requirements determined by the Modernization Development Plan for the Construction Industry. The development of prefabricated buildings is a major change in the construction method. A large number of building components of prefabricated buildings are produced and processed in the workshop. Only assembly operations are required on site, which reduces cast-in-place operations, and transforms traditional construction workers into prefabricated industrial workers. degree of industrialization. It is understood that Changzhou City issued the 'Implementation Opinions on Accelerating the Modernization of the Construction Industry' in 2015, which clarified the goals, tasks, key tasks and safeguards for the modernization of the city's construction industry.“Through sufficient investigation and research, when the policy was formulated, Changzhou put the application‘Prefabricated three boards’As a breakthrough in the promotion of prefabricated buildings in Changzhou, this policy was introduced two years earlier than the provincial department. Through the closed management of land transfer, construction drawing review, construction permit issuance, and completion acceptance, the Changzhou prefabricated construction project has been put on the track of sound development, one step ahead of its brother cities in Jiangsu Province.”Yang Kuanrong, director of the Green Building and Technology Division of the Changzhou Housing and Urban-rural Development Bureau, said. In 2015, Wujin District, Changzhou City successfully applied for the first batch of provincial-level construction industry modernization demonstration cities in Jiangsu Province. In the process of creation, Wujin District issued a number of policy documents such as the 'Wujin District, Changzhou City's Prefabricated Building Process Management Method (Trial)' to explore the establishment of a long-term working mechanism, and to review the mechanism, industrial agglomeration, and policies according to the actual local conditions. Guide innovation and development. During the three-year creation period, the newly started prefabricated building area is 4.1 million square meters, and 9 provincial-level construction industry modernization demonstration bases and 5 demonstration projects have been established, which have achieved good demonstration effects. In 2019, Wujin Green Building District was successfully approved as a provincial-level construction industry modernization demonstration park. This is another honor for Wujin Green Building District in the modernization of construction industry after the national and provincial construction industry modernization demonstration cities. The overall operator of Changzhou concrete prefabricated buildings located in Wujin Green Building District is the first large-scale production and research and development base for the complete industrial chain of prefabricated buildings in Jiangsu Province, focusing on BIM design, research and development, management, production, construction and technical training. At present, it is a large-scale and technologically advanced prefabricated building production base in East China, with an annual production capacity of 120,000 cubic meters. from“establish”the house becomes“take”For houses, resources are saved, energy consumption is reduced, construction period is shortened, and the modernization of the construction industry is further realized. The construction of demonstration bases has a very obvious demonstration and driving effect on the development of prefabricated construction engineering practice and management innovation, and in promoting the transformation and upgrading of the construction industry. At present, the city has a total of 29 national and provincial demonstrations, and has received a total of 38 million yuan of provincial subsidy funds, providing technical support for the city's prefabricated building components production, engineering design, and quality testing. According to incomplete statistics, by the end of 2019, there were more than 550 designated enterprises in the modernization and green building fields of the city's construction industry, covering the entire industrial chain of R&D, design, production, construction, testing, development, and construction waste treatment, with an output value of more than 70 billion yuan , the modernization of the construction industry has achieved remarkable results.
