by China clearly proposes to achieve carbon peak in 2030 and carbon neutralization in 2060, which puts forward higher requirements for energy conservation and emission reduction.
The cost of precast buildings has been declining.
In 2013, the general office of the State Council forwarded the green building action plan, which aims to “change the urban and rural construction mode and the development mode of the construction industry, improve resource utilization efficiency and achieve the binding goal of energy conservation and emission reduction”.
The change of population structure promotes the transformation and upgrading of the construction industry.
To sum up, whether from the perspective of national policy orientation, industrial upgrading demand, or market supply and demand, precast buildings will account for an increasing share of the construction industry, and will usher in a period of rapid development.
Firstly, because the front-end components can realize mass production and centralized raw material procurement, on the one hand, it can reduce the procurement cost, on the other hand, it can also enhance the quality control of raw materials.
Its core concept is to lengthen the chain of front-end production links and reduce the on-site construction links of the project, so as to realize the effect of mass production of components in the factory and then on-site assembly.
With the slowdown of China’s population growth and the acceleration of aging, the population engaged in the construction industry will continue to show a downward trend.
After that, the state has successively issued a series of relevant documents to support the transformation and upgrading of the construction industry.
When precast buildings form scale effect, this phenomenon will be exacerbated.
The construction industry, which has lost the demographic dividend, must seek a more efficient way to solve the contradiction between the current labor-intensive and the reduction of labor force.
At this time, the precast building should be born.
Compared with traditional architecture, precast architecture has three main advantages.
With the introduction of national policies, provinces and cities have successively launched the development goals of local precast construction industry during the 14th Five Year Plan period.
National policy guidance guides the development of precast buildings.
Among them, Hainan, Beijing and Jiangsu have clearly realized that precast buildings account for more than 50% of the new construction area.
While controlling raw materials, construction enterprises focus on how to improve construction efficiency.
In 2016, the guidance on vigorously developing precast buildings was officially issued, which clearly stated that “strive to make precast buildings account for 30% of the new building area in about 10 years”.
Secondly, precast buildings can flexibly adjust the order of the construction value chain, so that more nodes can be carried out in parallel or even in advance, shorten the overall cycle of the project, and optimize the cash flow of the enterprise.
At this time, more efficient precast buildings will be a powerful means for the transformation of the construction industry.
From the perspective of construction cost, the current traditional construction unit price is still lower than that of precast construction.
Author: he Guangzhen, senior partner of Peking University Zongheng, author of more articles to read the road of construction engineering reform, how to stop the collapse of the bridge, HR three pillar blue book, can enterprises without strategy go far, small team construction, three essentials, plain decoration, why the rapid development, click at the bottom left“.
At the same time, it can apply more advanced production tools of manufacturing industry during construction, and improve the quality and construction efficiency of construction projects.
Third, it promotes the integration of manufacturing industry and construction industry, so that they can complement each other.
Capital profit will promote the development of precast buildings faster.
The practical needs of energy conservation and environmental protection promote the development of precast buildings.
Precast building is a way to effectively improve the efficiency of on-site construction.
With the increasingly fierce competition in the construction industry, the industry profits are constantly compressed, and the construction enterprises are constantly exploring the road of development.
As a precast building with higher efficiency and less energy consumption, it will gradually increase its share.
The cost of traditional construction industry has gradually increased, which has promoted the development of precast buildings.
Therefore, on the whole, the cost of precast buildings has great room for decline.
But looking back on the past, the cost of traditional buildings has maintained an upward trend, especially in terms of labor cost, which has increased very rapidly.
Under the policy guidance, precast buildings will usher in a rising period.
As the pillar industry of China’s national economy, the energy consumption of construction industry is still growing.
