by 1、 Overview of the development of prefabricated building industry The call for building industrialization and prefabricated buildings is getting higher and higher, and the popularity of prefabricated building technology is increasing all over the country.
From the information of industrialization demonstration bases and projects fed back from all over the country, some industrialization achievements have been achieved, which is worth summarizing, upgrading and promoting.
However, there are many problems exposed during the implementation of industrialization, and the implementation effect is far from reaching the expected goal.
The current management system of the construction industry and the ecology of construction enterprises need to be reformed urgently to speed up the implementation of the high-quality development strategy of professionalization and professionalism in the prefabricated whole industry chain.
Otherwise, the healthy development and large-scale promotion and application of prefabricated buildings in China will be seriously affected in the future.
The integration and upgrading of the industrial chain related to prefabricated buildings and the construction of software and hardware in China have not yet been completed.
The professionalism and professionalism of the employees in engineering construction, design, construction and production units are low.
They lack the ability to manage industrialized technology and engineering experience.
They still manage industrialized projects according to the lowest price bidding concept of traditional cast-in-place structures, often resulting in unreasonable industrial planning and design schemes, The selected contractors and component processing plants do not have professional technology and industrialization implementation capability, which seriously affects the implementation effect of industrialization projects, resulting in high cost, poor quality, low efficiency and other problems in the project implementation process.
The current construction management system in China does not meet the requirements of industrialization development.
The division of the construction main body has caused the intersection of responsibilities and rights.
It is very difficult to coordinate the project as a whole.
The construction or supervision unit has seriously insufficient personnel and resources.
The ability to coordinate and manage the industrialization project as a whole is very lacking.
The professional technology and management level of the construction unit cannot meet the requirements of the industrialization of new buildings, As a result, problems such as poor quality, long construction period and high cost often occur in the process of project promotion, and even the conclusion that industrialization is not as good as traditional construction is reached.
We should explore and reform the current construction management mode as early as possible, and promote the management mode of combining general contracting with professional division of labor; Encourage enterprises to rely on technological innovation to develop new products, and rely on scientific management to improve quality and efficiency.
The core connotation of the modernization of the construction industry is to use industrial lean construction methods to build high-quality buildings and achieve the green development goal of energy conservation and emission reduction.
The experience of development at home and abroad has proved that prefabricated buildings are a systematic project.
Only by steadily promoting the project practice of talent team construction and project management step by step, and consolidating the foundation of product production and construction quality, can the high-quality and efficient development goal of prefabricated buildings be achieved.
The whole industry should realize that without talents and quality as the basis, it is not advisable or feasible to stay in the rush period and replicate low-quality buildings on a large scale.
In the face of the urgent need of transformation and upgrading to the modernization of the construction industry across the country, governments at all levels and relevant enterprises in the precast concrete industry should maintain a clear understanding, determine the industrialization technology system and development path according to local conditions, actively carry out the construction of pilot projects and demonstration projects, constantly summarize experience, draw lessons, and down-to-earth promote the modernization of China’s construction industry.
Those practices of promoting prefabricated buildings that disregard the objective conditions and seek perfection and success must be corrected.
Based on the existing problems in the implementation of prefabricated buildings in various parts of the country, and the strong contrast between the promotion of prefabricated assembly technology by local governments, all regions need to systematically summarize and reflect on the objectives, path, speed and other indicators of industrialization, adhere to the scientific attitude of seeking truth from facts, slow down, accumulate experience, and create a harmonious but different localization development path.
We should start with pilot and demonstration projects in some large and medium-sized cities with conditions nationwide, constantly summarize experience, train talents, and gradually promote them to small and medium-sized cities.
All enterprises should rely on market competition rules, build an industrial technology system and development platform based on regional characteristics, carry out technological management innovation, improve the technical level of building industrialization, and expand the application field of precast concrete.
We will make great efforts to cultivate a number of local industrialization companies and workers to ensure the completion quality and implementation efficiency at the initial stage of industrialization projects.
2、 The development of precast concrete enterprises There is a striking imbalance in the development and layout of precast plants across the country.
Prefabrication plants are mainly concentrated in large and medium-sized cities in the east.
Recently, PC plants have also been built in large cities in the central and western regions.
Generally speaking, the construction speed is too fast, resulting in a serious shortage of factory tasks in many places, while factory tasks in some regions are also saturated in the short term, The main reason is that the production time is mainly concentrated in the half year period from April to October.
The poor planning of project construction also seriously affects the operation efficiency and operating results of the prefabrication plant.
（1） PC Enterprise Development In 2019, the number of precast concrete production enterprises in China increased rapidly.
According to incomplete statistics, nearly 200 new precast plants were added in this year.
Up to now, there are more than 1000 precast plants with a scale of more than 30000 cubic meters in China.
More than 600 prefabrication plants have been built in the past three years.
At present, the production of prefabricated components mainly uses the capacity of the old prefabrication factory or the upgraded factory.
In addition to the good operation and management of some large enterprises, the general factory lacks the overall advantage of the industrial chain, so its operation status and economic benefits are poor.
Most of the new factories are in the trial operation stage, and there are great weaknesses in personnel, management and other software construction.
If there is no overall advantage of the industrial chain, there is a great business risk.
For example, given the investor’s positioning of the whole industrial chain base, some factories can overcome short-term difficulties and have a large space for long-term development..
