Accelerating transformation and upgrading, and making the construction industry greener and more efficient are behind the transformation and development of an industry.
With the continuous development of technology, the connotation and extension of this profession are also constantly changing.
The trend of “integrated” operations in various links is becoming increasingly evident.
In his view, compared to traditional construction workers, prefabricated construction workers have stronger professionalism, requiring knowledge and skills such as architectural drawing recognition, engineering measurement and positioning, and prefabricated component installation, as well as core competencies in on-site coordination and assembly construction.
These modules were transported to the site for direct lifting, truly realizing the building of a house like building blocks, with an overall assembly rate of 92%.” Li Zhiwu, the design director responsible for the project, introduced.
Assembled buildings adopt a large-scale and intensive approach, which can save consumables, reduce energy consumption, and reduce construction waste to a certain extent; Its mechanized installation during construction can reduce pollution such as noise, exhaust gas, waste, and wastewater emissions.
Previously, Dang Pengfei, who supervised and managed the production of MIC (Modular Integrated Building) in the factory, has now moved to the construction site, busy allocating materials, guiding decoration, and controlling construction quality.
It is precisely based on its green, environmentally friendly, efficient and economical characteristics that prefabricated buildings have become the main focus of promoting the transformation and upgrading of the construction industry in China since 2016.
Especially in recent years, after the deep integration of advanced manufacturing technology, a new generation of information technology, and the construction industry, the responsibilities of prefabricated construction workers have been extended to the entire production and construction chain of model design, prefabricated component production, and floor installation.
Industry insiders predict that with the increasing policy support and the comprehensive promotion of prefabricated buildings, the number of employees will reach 5 to 8 million in the next five years.
According to data from the Ministry of Housing and Urban-Rural Development, in the first half of 2022, newly constructed prefabricated buildings accounted for over 25% of the new construction area nationwide, with a total area of 2.4 billion square meters.
.
Divide the entire building into 6028 independent space units, build a house like “building blocks”, assemble a module in 30 minutes, assemble a suite in two hours, and erect five hundred meter high buildings a year…
Currently, the construction of the Zhangkeng Path Affordable Housing Plot in Longhua, Shenzhen, has come to an end, and workers are carrying out secondary decoration work on the splicing positions of each module.
Taking Yijia Symphony Joy Community as an example, lifting a module unit only takes 15 minutes and completing the installation of more than 1500 modules in 45 days.
The overall construction period only takes 9 months, while traditional building methods typically require about 2 years.
“Compared to traditional buildings, prefabricated buildings have significant advantages in carbon emissions,” Fu Wei said.
“The standard design was incorporated into the architectural design phase of the project, with each room as a basic module unit.
In recent years, with the increasing popularity of prefabricated buildings in China, prefabricated construction workers such as Dang Pengfei have continuously emerged, and were officially included in the national occupational classification catalog in February 2020.
Dang Pengfei, who has been engaged in the fabricated construction industry for more than ten years, has a deep feeling about this.
Many regions have also issued development goals for prefabricated buildings, with some provinces significantly accelerating.
Factory-built modules and on-site assembly of houses entered the Yijia Symphony Yue Community located in the Beijing Economic and Technological Development Zone.
Fu Wei once participated in the application work for the new profession of prefabricated construction worker.
At the same time, by putting a lot of work ahead of the factory, prefabricated building construction can greatly shorten the construction period and reduce labor.
He is not only responsible for MIC production and interior decoration, but also responsible for on-site construction management, “At the beginning of our employment, we mainly focused on the production and installation of traditional PC (concrete prefabricated components) components.
At the beginning of 2022, the “14th Five Year Plan” for the Development of the Construction Industry issued by the Ministry of Housing and Urban-Rural Development once again required that during the “14th Five Year Plan” period, the policy system and industrial system for the coordinated development of intelligent construction and industrialization of new buildings should be basically established, and the proportion of prefabricated buildings in new buildings should reach over 30%.
“Standardization of design, factorization of component prefabrication, and mechanization of construction”, the “industrialization of Chinese architecture” envisioned many years ago, is now becoming a reality, posing higher requirements for practitioners.
The so-called prefabricated building refers to a new type of building constructed by completing the processing of building components in the factory in advance and then using prefabricated construction on site.
For example, Beijing has made it clear that by 2025, the proportion of prefabricated buildings in new buildings will reach 55%, while Hainan has set a goal of over 80%.
According to Fu Wei, currently 31 provinces across the country have issued relevant incentive policies, which are conducive to actively promoting the development of the prefabricated construction industry.
For prefabricated architectural designers, we also need to participate more in the production and construction processes.”.
The structure, interior decoration, water and electricity, and bathroom facilities of the room were all produced in advance in the factory, basically reaching the level of fine decoration and occupancy.
We need to clearly grasp design drawings, be familiar with production molds, and understand how to organize and arrange production and construction.
Li Zhiwu told reporters that currently, the new designers in the company are all going to the production workshop for more than half a year.
With the development of prefabricated buildings, technology continues to iterate, and now it is MIC modular integrated buildings.
The “Several Opinions of the Central Committee of the Communist Party of China and the State Council on Further Strengthening the Management of Urban Planning and Construction” issued in February of that year proposed to strive to use about 10 years to make the proportion of prefabricated buildings in new buildings reach 30%.
Yellow and green houses came into view, and 1504 modules were assembled together, forming this modular building group with the highest floors and the largest building scale in China.
