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.

Although the objectives and tasks of the whole province have been successfully completed, the overall quality of development is not high.

In 2022, Shanxi will actively promote the development of precast buildings.

The reporter of Shanxi Evening News learned that Shanxi cities have actively cultivated enterprises such as production, design and construction, and 13 new precast construction related enterprises have been added, with a total of 46.

Some bases also serve the surrounding Beijing, Shaanxi, Hebei and other places.

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.

Civil buildings account for 47%, not more than half.

First, there are few civil buildings.

90 with assembly rate lower than 50%, 38 between 50% and 60%, and 69 higher than 60%.

Except Datong City and Jinzhong City, all other cities have completed their annual goals and tasks.

For example, the promotion measures are not in place and the incentive policies are not effectively implemented.

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.

Strengthen the quality management of precast components, actively adopt the method of factory supervision, and implement the whole process quality responsibility traceability.

Although it has developed rapidly, there are still some problems.

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.

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 proportion of precast buildings in the newly-built construction area of the whole province will reach 21% (31% in Taiyuan and Datong).

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.

At the same time, supervise and guide the large-scale public buildings invested by the government to adopt steel structure, carry out the pilot of steel structure housing, cultivate residential buildings with high assembly rate, and steadily promote precast concrete buildings.

In addition, the quality of development is not high.

Among the 197 projects in the province, there are 93 civil buildings and 104 industrial buildings.

It is reported that according to the classification of building types, residential buildings are 4.3553 million square meters, public buildings are 1.3498 million square meters and others are 2.0602 million square meters.

More than 60% of the projects with high assembly rate account for 35%, but they are all industrial construction projects without residential construction projects.

Second, there are few projects with high assembly rate.

On February 16, the reporter learned from the Department of housing and urban rural development of Shanxi province that in 2021, Shanxi’s precast construction policies and measures were gradually implemented, the technical standard system was more perfect, the number of enterprises was growing, and the industrial layout was more reasonable.
