Therefore, taking the construction of prefabricated building demonstration cities as an opportunity, some demonstration cities have independently explored and studied local standards according to local conditions, which not only lays a foundation for the smooth promotion of local prefabricated buildings, but also provides a reference for the formulation of national standards
.
After the rapid development in recent years, what positive explorations have these demonstration cities made, what replicable and promotable experiences have been formed, what problems and shortcomings exist at the same time, and how to improve in the next step to better play the leading role of demonstration are very worthy of attention and research
.
But at the same time, the technical standard system is not perfect, the overall and systematic design is missing, the collaborative development of the industrial chain is not deep enough, the level of intelligent construction is not high, and the propaganda and promotion is far from enough, which are reflected in the process of the development of prefabricated buildings in various demonstration cities
.
It is easy to set high goals, and the key and difficult point is to implement them
.
Based on this, in order to accelerate the transformation and upgrading of the construction industry, as soon as possible out of a high-tech content, good economic benefits, low resource consumption, less environmental pollution, human resources advantages to give full play to the new road of building industrialization, vigorously develop “standardized design, factory production, assembly construction, integrated decoration, information management, intelligent application” as the core of the construction industry Prefabricated building has become an important measure for China’s construction industry to seek innovation and change in recent years
.
At the initial stage of promotion, in order to fully stimulate the market vitality and mobilize the enthusiasm of enterprises to participate in the field of prefabricated construction, Shanghai, Beijing, Shenyang and other cities have built a relatively perfect incentive mechanism in terms of floor area ratio, pre-sale, provident fund, finance, finance, transportation, etc
.
In the period of the 14th five year plan, facing the new situation, new tasks and new requirements, as a demonstration city, we need to make persistent efforts to grasp the key points, make up for the weaknesses, strengthen the advantages, further innovate and optimize the development path, and build a good industrial ecology, so as to better play the leading role as a national prefabricated construction demonstration city
.
Compared with the traditional construction method, the prefabricated building, whether it is prefabricated component production or on-site hoisting, contains a higher technical content, which requires a group of skilled construction workers
.
To this end, Shaoxing has explored and formed a “decentralized training, unified assessment” evaluation mode of skills training for assembly construction industry workers; Shenzhen has helped to improve the ability of assembly construction industry workers by carrying out public welfare training, project observation, study and investigation, and industry exchange, and has taken the lead in creating professional and technical titles of assembly construction in China; Shenyang has taken the lead in establishing professional and technical titles of assembly construction Shenyang modern construction industry training center has been set up on the basis of China University of architecture and Shenyang Construction Industry Association; Hangzhou city has a training course jointly organized by local construction industry association to train assembly construction industry workers and issue certificates to qualified trainees
.
Most cities take the lead in requiring prefabricated construction in government invested projects, and take this as a breakthrough point to gradually increase the promotion of prefabricated buildings in the field of commercial buildings and residential buildings
.
With government investment projects as a breakthrough, gradually increase the promotion of prefabricated buildings
.
Government guidance, market power, and various measures to develop prefabricated buildings
.
Improve the technical specifications and evaluation system of prefabricated buildings according to local conditions
.
According to the “guidance on vigorously developing prefabricated buildings” issued by the general office of the State Council and a series of policies issued by the Ministry of housing and urban rural development, the first batch of 30 prefabricated building demonstration cities in China have formulated a more detailed local version of prefabricated building development plan based on their own reality
.
To sum up, on the basis of giving full play to their existing market and industrial advantages, the first batch of 30 prefabricated building demonstration cities in China have taken a series of powerful measures to promote the vigorous development of local prefabricated buildings, such as establishing and perfecting the policy support system, studying and formulating local standards, cultivating and supporting leading enterprises, and building modern industrial clusters Some cities have also formed their own unique development mode, constantly attracting other cities in the country to “learn from the experience on the spot”
.
In view of the imperfection of the corresponding market at the initial stage of prefabricated building promotion, most of the enterprises are lack of experience The enthusiasm is not high
.
For a long time, China’s construction industry is large but not strong, the level of industrial chain collaboration is not high, the organization and management is fragmented, and the construction mode is extensive and backward
.
Therefore, many demonstration cities have taken some effective measures in supervision
.
Build a diversified incentive mechanism to fully stimulate market vitality and mobilize the enthusiasm of enterprises
.
● vigorously cultivate the construction industry workers to provide talent support for the development of prefabricated buildings
.
In order to give full play to the research advantages and professional guidance role of the industry media, promote experience exchange and serve the front-line practice, China Construction daily spent half a year in-depth studying the main practices and problems of the first batch of 30 prefabricated building demonstration cities in China, and launched a large series of reports on “Research on the development of national prefabricated building demonstration cities” It provides valuable information reference for relevant decision-making and industrial development, and has received positive feedback from all aspects of the industry
.
After the general office of the State Council issued the guidance on vigorously developing prefabricated buildings in 2016, Beijing and other 30 cities were recognized as the first batch of prefabricated building demonstration cities by the Ministry of housing and urban rural development in 2017
.
Some cities have listed the prefabricated building industry as a local key industry development plan, and some cities have set up special leading groups or established a joint conference system to take various measures at the same time Comprehensively promote the development of prefabricated buildings
.
With the help of “prefabricated building information service and supervision platform”, Nanjing realizes the information exchange, information sharing and whole process management of the whole industry chain Trace tracking and comprehensive quality supervision..
.
In the early stage of prefabricated building promotion, the technical system and evaluation standards are not perfect, and some areas are even blank, which is not conducive to the rapid promotion of prefabricated building
.
Throughout the development of the first batch of 30 prefabricated building demonstration cities in China in recent years, the governments of all cities attach great importance to it
.
For example, Qingdao implements the pre evaluation system of new prefabricated buildings, and the projects that do not meet the requirements of planning conditions, construction proportion and assembly rate of prefabricated buildings in construction conditions can not apply for construction license; Jining strengthens supervision in the process of construction drawing review, and the projects that fail to meet the development requirements of prefabricated buildings in accordance with the construction condition opinions will not pass the review; Shanghai will not pass the review according to the construction conditions According to the implementation requirements of prefabricated building, management nodes are set up in the construction application, construction drawing review, construction permission and other links, and the prefabricated building area, structural form and other information are marked on the construction drawing review record certificate and completion acceptance record certificate
.
Strictly implement the whole process supervision, and promote the high-quality implementation of prefabricated construction projects
