by Prefabricated building is a significant change in construction means and methods.
Prefabricated building methods are widely used in the construction field in developed countries.
According to the relevant statistics released by the Ministry of housing and urban rural development in 2016, the construction in China is still dominated by on-site pouring, and the proportion of prefabricated buildings in new buildings is less than about 5%, which is far from the international advanced level.
In recent years, China has successively issued the development policy of prefabricated buildings and formulated the action plan and objectives of prefabricated buildings, as shown in the following table: opportunities and challenges of PC prefabricated component factories – accompanied by Shiqiao whole process technical service.
According to the requirements of national prefabricated policies, at present, 31 provinces, autonomous regions The local people’s governments of municipalities directly under the central government have issued specific implementation opinions, plans and action plans for prefabricated buildings.
Among them, Beijing, Shanghai, Tianjin, Zhejiang, Jiangsu and other economically developed regions require the assembly rate to reach more than 30% by 2020, far higher than the national target, most regions require it to reach 15% or more, and some central and western provinces, Ningxia Qinghai and other regions put forward the target of 10% according to local conditions.
At the same time, local governments also actively give full incentives to industrial development through tax incentives, land support, financial subsidies, plot ratio incentives and other methods.
The local support projects are shown in the following table: opportunities and challenges of PC prefabricated component factory – opportunities and challenges of Shiqiao whole process technical service accompanied by PC prefabricated component factory – Shiqiao whole process technical service accompanied.
With the call of national policies and the efforts of governments at all levels, the fabricated construction industry is undergoing a process of rapid promotion, development, growth and improvement, Some regions have achieved considerable performance and results, and have a considerable number of PC prefabricated component factory enterprises, some of which have a considerable production scale.
According to industry statistics, by the end of 2019, about 800 prefabricated component manufacturers had been built and put into operation in China.
Among them, there are about 400 in Jiangsu, Zhejiang and Shanghai, about 120 in Beijing, Tianjin and Hebei, and about 90 in the Pearl River Delta.
The leading role of key development areas in Beijing, Shanghai and Shenzhen has gradually become prominent.
EPC general contracting enterprises account for about 40%, and market supply enterprises account for about 60% (including OEM enterprises).
China’s prefabricated construction industry has ushered in a period of rapid development.
However, China’s industry as a whole is still in its infancy.
In order to achieve real application and down-to-earth implementation of prefabricated construction, most areas have not reached the actual goal.
After most prefabricated component factories and enterprises are actually put into operation, there are also many problems to be solved.
At present, in addition to several key areas in the industry, such as Beijing, Shanghai, Shenzhen, Nanjing, Hangzhou and Suzhou, prefabricated component factory enterprises in most other areas have the situation of “production seems to be booming, but basically there is no expected profit”.
Among them, in most areas, only a few factory enterprises undertake prefabricated component procurement projects in the commercial housing market, and most factory enterprises can only undertake component procurement of some affordable housing projects.
They still need to rely on corresponding policy support and cannot go to the market completely independently.
For some production enterprises assigned to the market “share”, the actual profit situation is not ideal, and a small number of enterprises have fallen into the situation of “more output and more compensation”.
The main reasons are as follows: first, according to the development trend of prefabricated buildings, the general contractor must be the main person responsible for the design, production and construction of construction projects.
The actual situation is that it is difficult to standardize the implementation of the general contracting mode, and it is difficult to play a role in the advantages of assembly integration and energy-saving benefits.
Secondly, our understanding of PC prefabricated component factory and operation management has considerable limitations, and there are even many misunderstandings.
The development of prefabricated building components in China benefits from the introduction and learning of technologies from Europe and Japan.
Most of them are imitated uniformly, which greatly limits our investment positioning and management thinking, which is embodied in the following aspects: the next 10 years will be a higher development stage of prefabricated buildings in China, China’s prefabricated construction industry market will be one of the most dynamic markets in the construction field in the world.
Therefore, PC prefabricated component factory will face a better development opportunity.
At the same time, it will also face unprecedented challenges such as market, policy and technology.
On the one hand, with the increase of the proportion of prefabricated buildings, the procurement volume of prefabricated components in the market will reach the peak of supply.
There are higher requirements in architectural design, split design, types of prefabricated parts, construction accuracy, decoration and quality control, which will further test the technical quality management and production and supply capacity of factories and enterprises.
On the other hand, prefabricated buildings will show a diversified development trend, from affordable housing to commercial housing, township and village housing construction market, so as to accelerate the comprehensive coverage of the whole field of housing construction.
Prefabricated parts with exterior finishes, shapes and customized parts with interior decoration requirements will be more common.
On the basis of prefabricated concrete structure technology, the application of prefabricated steel structure technology will also be greatly improved, as well as the practical application of municipal prefabricated construction technology such as bridges and elevated expressways.
The technological R & D and production scale of green materials such as light wallboard and aerated board will also be further expanded.
In addition, the market competition will be more intense.
The assembly start-up area and steady progress area will be regarded as the important market strategic place.
Large group enterprises will start the layout in advance, expand the market scope and realize regional large-scale operation.
Especially for the construction enterprises with special qualification of general contracting, some enterprises have begun to layout in East China, South China and even the whole country.
At the same time, private enterprises will also accelerate the layout and expand market share..
