by Click the blue word to pay attention to the housing and urban rural development bureaus of our cities.
All relevant units: according to the summary and development of precast buildings in 2021, our department has summarized and now released the development of precast buildings in 2021 as follows: I.
Development in 2021.
In 2021, the policies and measures of precast buildings in the province will be gradually implemented, and the technical standard system will be more perfect, The number of enterprises is growing, and the industrial layout is becoming more reasonable.
In the whole year, 7.7653 million square meters of new precast buildings were started, accounting for 23.26% of new buildings, and the annual target and task were successfully completed.
（1） The work of each city is promoted.
Each city implements the implementation opinions on vigorously developing precast buildings and the implementation opinions on accelerating the industrialization of new buildings, and actively promotes the industrialization of new buildings represented by precast buildings.
Except Datong City and Jinzhong City, all other cities have completed their annual objectives and tasks (see the annex for details).
The general offices of Jincheng and Yuncheng Municipal People’s governments and the housing and urban rural development bureaus of Shuozhou, Luliang, Jinzhong, Changzhi and other cities issued documents respectively, put forward development objectives in combination with local conditions, defined the scope of projects that must adopt precast buildings, divided the division of responsibilities of various departments, and issued incentive and incentive measures, which greatly promoted the development of local precast buildings.
（2） Development of industrial base: all cities have actively cultivated production, design, construction and other enterprises, and 13 new precast construction related enterprises have been added, with a total of 46.
There are 24 manufacturers of parts and components in the province, with a production capacity of about 36.8 million square meters, double that of 2020.
All cities actively connect with Shanxi construction investment group to jointly promote the construction of industrial bases.
Linfen park has registered and obtained the business license, Changzhi park has signed the investment agreement, Yangquan park has completed the negotiation of investment conditions, and Datong park is in communication.
At present, 11 cities divided into districts in the province have industrial bases, realizing full coverage of industrial bases within 100 kilometers and full coverage of concrete structure, steel structure and wood structure system, meeting the development needs of precast buildings in our province.
Some bases also serve the surrounding Beijing, Shaanxi, Hebei and other places.
（3） The implementation of the project and the construction of the demonstration project have achieved remarkable results, driving the smooth progress of the project in 2021.
Classified by building type, residential buildings are 4.3553 million square meters, public buildings are 1.3498 million square meters and others are 2.0602 million square meters.
According to the classification of structural forms, concrete structure buildings are 4.6867 million square meters, steel structure buildings are 2.784 million square meters (including 243000 square meters of steel structure residential buildings), wood structure buildings are 31400 square meters and others are 263100 square meters.
The construction area of assembly decoration is 432600 square meters, accounting for 12.07% of the newly started construction area.
The number of projects adopting EPC mode accounts for 22.08%.
2、 Main problems (1) the promotion measures are not in place.
In recent years, the state and the province have successively issued a series of policy documents, and all cities have also formulated implementation plans, but the implementation effects are quite different.
Relevant departments of Taiyuan have closely cooperated, refined measures and actively promoted the development of precast buildings, which are in the forefront of the province in terms of quantity and quality, and played a demonstration and driving role of pilot cities.
However, some cities have not made great efforts to promote and have not fully implemented the relevant policies.
First, the precast building was not promoted according to the implementation scope determined in the document.
Some cities have proposed that government investment projects, new commercial residential projects with an area of more than 100000 square meters, and new commercial and office projects with an area of more than 30000 square meters or a single area of more than 20000 square meters should adopt precast buildings.
However, from the perspective of implementation projects, the number, type and scale of projects have not strictly implemented the requirements put forward by this city.
Second, the incentive policy has not been effectively implemented.
All cities did not actively coordinate with relevant departments to implement the policy requirements of construction conditions, plot ratio reward, capital reward and subsidy, green finance and so on.
（2） The quality of development is not high.
Although the objectives and tasks of the whole province have been successfully completed, the overall quality of development is not high.
First, there are few civil buildings.
Among the 197 projects in the province, there are 93 civil buildings and 104 industrial buildings.
Civil buildings account for 47%, not more than half.
Second, there are few projects with high assembly rate.
90 with assembly rate lower than 50%, 38 between 50% and 60%, and 69 higher than 60%.
More than 60% of the projects with high assembly rate account for 35%, but they are all industrial construction projects without residential construction projects.
3、 The next step is to thoroughly implement the spirit of the 2021 provincial assembly meeting on the promotion of precast buildings and the 2022 work requirements of the Ministry of housing and urban rural development, and actively promote the development of precast buildings.
The proportion of precast buildings in the new construction area of the whole province should reach 21% (31% in Taiyuan and Datong).
Focus on the following work.
（1） To promote the implementation of projects, all municipal housing and urban rural development bureaus should take the initiative to connect with the development and reform, natural resources, administrative examination and approval and other departments, jointly promote the implementation of policies, implement the requirements of precast buildings in the links of project initiation, land transfer, planning conditions and administrative examination and approval, strictly implement the requirements of the project scope and type of precast buildings, and ensure the completion of annual objectives and tasks.
We should urge and guide large-scale public buildings invested by the government to adopt steel structure, carry out pilot projects of steel structure housing, cultivate residential buildings with high assembly rate, and steadily promote precast concrete buildings.
（2） Strengthen quality and safety supervision.
All cities should strengthen the quality and safety supervision of precast construction projects under construction.
Strengthen the quality management of precast components, actively adopt the method of factory supervision, and implement the whole process quality responsibility traceability.
The quality and safety control of key parts and processes such as construction and installation, node connection grouting, sealing and waterproof shall be strengthened by means of video recording and on-site supervision of all parties..
