Today, the Zhejiang Provincial Department of Construction issued the “Key Points for Quality and Safety Supervision of Prefabricated Building Construction in Zhejiang Province”. This key point is mainly aimed at building projects where the upper main structure adopts two common structures, prefabricated concrete structure and prefabricated steel structure. It supervises quality and safety behavior, engineering entity quality, construction site safety, and proposes advocacy requirements for green construction and occupational health, information management, and other aspects of prefabricated buildings..
It is important to establish an information management system for prefabricated construction projects, in order to achieve quality and safety management throughout the entire construction process and traceability of quality and safety responsibilities..
The key points are clear, and the construction unit should fulfill the primary responsibility for the quality and safety of prefabricated construction projects. The project leader of the construction unit should be authorized in writing by the legal representative of the unit and sign a lifelong commitment letter for quality and safety..

Encouraging the development of prefabricated buildings has become one of the important construction industry policies in China at present. Since the release of the Guiding Opinions on Vigorously Developing Prefabricated Buildings in 2016 (Guoban Fa [2016] No. 71), a large number of policy documents related to prefabricated buildings have been released in the context of China’s construction industry scale reaching new highs. Various standards have gradually improved, development indicators have become clearer and higher, and various parts of the country have shown a high-speed development trend of simultaneous progress. Key development areas have taken the lead in entering the stage of high-quality and green low-carbon development..
1. The prefabricated construction industry is an important development direction for the country in the field of construction.
Prefabricated buildings refer to buildings that are transported from factories to construction sites, and assembled and installed on site through reliable connections. Compared with traditional cast-in-place construction, the construction site of prefabricated buildings does not require a large amount of manpower and material resources. Most building components and parts are completed in the production workshop, reducing the loss of building materials and the generation of construction waste, and reducing carbon emissions throughout the entire life cycle of the building. It is the most in line with the “carbon neutrality” concept of construction, in line with the national concept of green and sustainable development, and is an important development direction for the country in the field of construction. From the classification of structural materials, prefabricated buildings can generally be divided into prefabricated concrete buildings, prefabricated steel structure buildings, and prefabricated wood structure buildings..
Prefabricated buildings have been widely promoted and supported worldwide due to their high efficiency, energy conservation, environmental protection, and low-carbon characteristics. The specific advantages are as follows:.
Therefore, whether from the perspective of economic or social benefits, prefabricated buildings are regarded as one of the important paths for the transformation and upgrading of the construction industry, and have a positive effect on achieving the national “dual carbon” goals..
Encouraging the development of prefabricated buildings has become one of the important construction industry policies in China at present. Since the Guiding Opinions on Vigorously Developing Prefabricated Buildings (State Council Document [2016] No. 71), in the context of China’s construction industry reaching new highs in scale, a large number of policy documents related to prefabricated buildings have been released, various standards have been gradually improved, development indicators have become clearer and higher, and various regions across the country have shown a high-speed development trend of simultaneous progress. Key development areas have taken the lead in entering the stage of high-quality and green low-carbon development..
From the perspective of the popularity of prefabricated buildings, foreign countries started earlier in the field of prefabricated buildings. The penetration rate of prefabricated buildings in developed countries such as the United States, Japan, and Europe has currently reached over 70%, while prefabricated buildings in China are just beginning. In 2022, the newly constructed prefabricated buildings in China reached 810 million square meters, an increase of 9.5% compared to 2021, accounting for 26.2% of the new construction area. There is ample room for future penetration rate growth..
Newly started prefabricated building area in China from 2017 to 2022 (100 million square meters).
Prefabricated buildings have seen frequent policies and clear development goals in recent years. The relevant policies revolve around promoting green buildings and accelerating the process of building industrialization, repeatedly proposing to vigorously develop prefabricated buildings..
At present, concrete and steel structures are the main structural types of prefabricated buildings in China. According to the application field, it can be divided into bridge steel structures, modular building products, and building steel structures, all of which belong to the field of prefabricated steel structures. As one of the important supporting materials for prefabricated buildings, steel structures have many advantages such as high strength, light weight, good seismic performance, high space utilization, high industrialization, short construction period, low construction cost, high economic benefits, strong plasticity, wide application fields, and recyclability..
In terms of penetration rate of prefabricated steel structure buildings, the penetration rate of prefabricated steel structure buildings in China increased from 4.1% to 6.9% from 2019 to 2021, and is expected to rise to 40.0% by 2035, with a compound annual growth rate of about 15.30%. The market penetration rate of prefabricated steel structure buildings in China is increasing..
