The industrialization of the construction industry is simply to build a house like a car through industrialization. From Baguio to Greenland and Poly, they have begun to lay out smart and assembled (frame) buildings. "Made in China 2025" also pointed out: "Made in China must transform to innovation, intelligence, green and high-end, and find its own new advantages, so that it can gradually transform itself from an export-oriented economic development model to a global economy based on me. A new model of open economy in the value chain."
  
From smart phones to smart homes, from drones to unmanned vehicles, new technologies and industrial upgrades are sweeping all walks of life, including the most traditional real estate industry.

A new model of open economy in the value chain."
  
Driven by new technologies and policies, a change around the construction industry is also quietly emerging.
  
Construction industry enters the transition period
Therefore, green environmental protection, energy saving and emission reduction has become a major problem that the construction industry must face.
  
There is a word in the industry called intelligent assembly building, that is, through frame-type factory manufacturing and assembly construction, the purpose of improving efficiency and energy saving and environmental protection is achieved while shortening the construction cycle. According to industry insiders, compared with traditional construction methods, the labor required for intelligent prefabricated buildings can be reduced by at least 30%, the construction period of the total project can also be shortened by 30%, and construction waste can be reduced by more than 80%.
  
However, this industry is in its infancy in China, and its penetration rate is not high.
  
According to public data, my country's prefabricated buildings account for only about 3% of the newly built building area, but this data accounts for as much as 90% in Japan and the United States.
  
At present, only a few real estate companies such as Country Garden and Vanke are in this field. In order to promote the development of prefabricated buildings in the country, in September 2016, the General Office of the State Council issued the ''Guiding Opinions on Vigorously Developing Prefabricated Buildings'' and proposed that it will take about 10 years to make prefabricated buildings account for the proportion of new construction area Reach 30%, of which strive to reach more than 15% in 2020.
As the real estate economy enters the second half, urban land has become a scarce resource, and the construction industry is also facing an upgrade from extensive growth to green and more efficient ways. At present, the newly started area of housing construction in the construction industry is about 5 billion square meters per year. Such data has reached the "peak" and will be gradually reduced in the future. On the other hand, statistics show that the construction waste generated by new construction, demolition and decoration in China is about 1.55 billion -2.4 billion tons every year, and the real estate industry accounts for more than 40% of China's carbon emissions.
With the introduction of local landing rules, the development of the industry into the policy dividend period. The goal of Beijing's landing policy clearly stipulates that by 2018, the proportion of prefabricated buildings in the new construction area will reach more than 20%, and by 2020, the proportion of prefabricated buildings in the new construction area will reach more than 30%; Shanghai's policy The goal is to achieve a single prefabrication rate of more than 40% or an assembly rate of more than 60% during the "13th Five-Year Plan" period; and in Guangdong Province's landing policy, it is clearly proposed that by 2020, the proportion of prefabricated buildings in new buildings will reach 15%, and by 2025, the proportion of prefabricated buildings in the Pearl River Delta urban agglomeration will account for more than 35% of the new construction area. In addition, Jiangsu, Zhejiang, Hubei, Shandong, Hunan, Sichuan and other provinces and cities have also issued local landing policies accordingly.
  
This is not an easy task. Therefore, with the local policy together with the corresponding subsidy policy. For example, Beijing will give financial rewards to those who adopt prefabricated buildings and meet the de facto standards; Shanghai will subsidize the unit area according to a certain proportion, and the subsidy per square meter is 100 yuan; the subsidy in Guangdong Province is based on projects, and the eligible The maximum amount of individual funding does not exceed 2 million yuan.
  
With the encouragement of the government, the tepid prefabricated buildings in the past ten years have ushered in a new round of wind.
  
According to the Prospective Industry Research Institute, the scale of China's prefabricated construction market will exceed 2 trillion yuan in 2020 and reach 4.7 trillion yuan in 2025.
  
Secret construction industry upgrade behind the black technology
  
In fact, the system characteristics of intelligent prefabricated construction projects determine that the development of prefabricated buildings must require the coordination of the whole industry chain, from design, production, construction to delivery and other links are different from the original building system. Country Garden is an early domestic enterprise to enter this field. Its innovative and developed SSGF high-quality construction system is not only limited to the assembly field, but also combines the advantages of cast-in-place to fully realize the industry in terms of construction methods, management, technology and materials. upgrade.
  
Recently, Xiong out of ink please note that he was invited to the construction site of the Dongguan Shatian project in Country Garden to witness the landing of SSGF. Due to the different construction methods, it is completely different from ordinary construction sites. The infrared induction car washing system set up at the entrance and exit of the gate can clean the silt of the vehicles in time, and the roadside is also equipped with automatic sprinkler devices to sprinkle water on the road from time to time, making the whole road from the gate to the construction site clean and tidy.
According to its official introduction, SSGF refers to "Safe & share safety sharing", "Sci-tech scientific and technological innovation", "Green green sustainability" and "Fine & fast high quality and high efficiency". Based on the industrialization of assembly, cast-in-place, electromechanical and internal installation, SSGF integrates technologies including graded standardized design, mold air-to-air assembly, artificial intelligence application, fully interspersed construction management and on-site integrated decoration, so that the main construction can be synchronized with the decoration project sub-floor.
  
Let's take a look at what "black technology" construction technology is used behind this.
  
The first is the use of high-precision process system. This is also the basis of SSGF's construction technology. It adopts aluminum alloy template technology and concrete pouring and forming, which can realize standardized production in the factory. After each floor is built, it moves up through intelligent climbing wall, which greatly improves the quality and efficiency of the building, and also solves the problem of plastering the internal and external walls, Eliminate hidden quality hazards such as hollowing and cracking.
The second is the assembly construction system. On the construction site, not only can't see scaffolding, mixers, etc., but also can't see piles of sand, bricks, reinforced concrete and other building materials. Most of the components needed for building houses such as floors and stairs are built in the factory., Transported to the construction site for splicing and pouring, greatly improving the construction efficiency, while more solving environmental protection problems, and reducing construction waste. In addition, temporary facilities such as gates, fences, protective railings, stairs, and material stacking areas on site can be disassembled and recycled many times, which feels like a car assembly line.
Third is interspersed with the construction system. Generally speaking, the traditional construction method is to wait for the main building to be capped before finishing fine decoration. Taking 27-29 storey high-rise houses as an example, the delivery period is 25 months. However, in the SSGF system, when the main body is constructed, prefabricated interior wall panels, doors and windows, railings, water supply and drainage, circuit lighting, interior decoration and other synchronous flow operations are carried out. Xiong Chumo please note that when the house was built to the 20th floor, the 17th floor had already begun to be renovated. Similarly, taking the 27-29 floors as an example, the construction period can be shortened by 8-10 months.
With the blessing of these black technologies, Country Garden took the lead in organizing "all-weather construction site opening" in the industry. After the project progress and technical conditions reached the opening conditions, it accepted customers, prospective owners and owners to make appointments to visit the construction site to see the physical quality all the time, breaking the traditional way of buying a house in a building that can only visit model rooms. It can go to the construction site to see before buying.
Next Battlefield
  
With the promotion of policy and the further maturity of technology, an arms race around the construction industry has begun to be staged. After all, in such a more concentrated and longer cycle industry, whoever can seize the opportunity is more likely to occupy this market.
Obviously, Country Garden has been at the forefront of the industry in this field with SSGF. Compared with the general assembly method, SSGF can also realize the production and assembly process of large-scale building components at the construction site, and realize the industrialization of construction in the form of "air assembly factory. At present, Country Garden has promoted SSGF in 28 provinces including Beijing, Guangdong, Sichuan, Chongqing, Jiangsu, Hubei, Hebei, and Henan. As of early August 2018, Country Garden has adopted the SSGF high-quality construction system in 59 regions and more than 400 projects., And will gradually promote its use across the country.
  
Greenland has also carried out research and development and pilot work on prefabricated buildings in Shanghai, Chengdu, Hefei, Kunshan and other places. In some new projects, the area of prefabricated buildings has reached 100.
  
Poly, on the other hand, chose to work with Broad Housing to enter this field by building an assembled building intelligent factory relying on BIM, Internet of Things and big data technology. At the same time, Poly Real Estate (600048, Guba) also has capital cooperation with Broad Housing to support Broad Housing's headquarters research and development platform. At present, Broad Housing has signed a number of prefabricated construction projects with 12 countries, including Russia and Poland.
  
Zhongmin Zhuyou is a company under Zhongmin Investment that focuses on the research and operation of the entire industrial chain of prefabricated buildings. At present, it has deployed green building technology parks and floor-to-floor prefabricated buildings in 42 cities across the country, including Changsha, Shanghai, Hangzhou, Nanjing, Shenzhen, and Foshan. Construction project.
  
The prefabricated construction market is stimulating the rapid growth and maturity of this industry, but it still faces many challenges in the short term.
  
First of all, the construction cost is higher than the traditional construction technology in the short term. The relevant person in charge of Country Garden said that in the SSGF system, the construction cost is at least 100 yuan per square meter higher than the traditional method, but from the perspective of the reduction of the construction period, the construction speed can be 8-10 months faster than the traditional construction period, making the overall construction of the building The benefits are better than traditional construction projects.
  
On the other hand, the industrial chain has not yet been formed. Among them, in addition to the system required for prefabricated buildings has not been promoted nationwide, it also involves the upgrading of the entire team of construction workers. In order to solve this problem, Country Garden has established the SSGF Industrial Worker Training School to regularly conduct skills training for workers and migrant workers on the construction site. There are both theoretical training and technical practical guidance. At the same time, it is also driving prefabricated template suppliers, Sanitary ware suppliers and other common development, and gradually promote the formation of the prefabricated construction industry chain. The formation of this industrial chain is also expected to pull the development of upstream and downstream related enterprises, including intelligent climbing frame, partition board, assembly interior and smart home.
  
In any case, once the reform around the construction industry starts, it will not stop, and the prefabricated construction industry has ushered in a new round of golden development period.
