How to promote the development of building industrialization in the era of "BIM+"? Many people have different views on the development of building industrialization. With the promotion of BIM technology, the construction industry has developed rapidly. In the new information age, all countries have launched corresponding research and some policy guidance, especially Germany put forward the concept of Industry 4.0 a few years ago, which makes the new industrialization characterized by information technology become the focus of the whole global competitiveness in the future. Implementing the strategy of promoting industrialization by informationization is a breakthrough in transforming and upgrading the traditional construction industry, and the only way for China's architecture to move from a "building power" to a "building power".

After these years' development, China's architecture has made great achievements in the process of rapid urbanization, but at the same time, it has also brought problems such as high pollution, high energy consumption, low quality and low efficiency. Therefore, building efficiency has become the bottleneck of the redevelopment of China's construction industry, and China's construction industry, which exceeds 50% of the global engineering quantity, needs to seek a brand-new design and construction mode.

China's economic development and environmental development are under great pressure from the construction industry, so the responsibility of the construction industry is actually great. Especially in the new economic transition period, the country has put forward the development strategy of "One Belt, One Road", and the construction industry in China has also assumed the responsibility of going global. We should not only build ourselves, but also go international. Now the construction industry is also a process of globalization, which needs to inject new vitality into the construction industry in China. "China Construction" is also in urgent need of upgrading and transformation to support the country's "Belt and Road" strategy.

Building Industrialization: Domestic Traditional Reality and Foreign Advanced Application Situation

Building industrialization makes the project development have the advantages of controllable quality, controllable cost and controllable progress. As a mature technology, building industrialization has been widely used in developed countries. Experience has proved that the application of building industrialization technology has greatly improved the comprehensive efficiency of building construction, and at the same time, the construction period is only 1/3 of the traditional method, which greatly reduces the labor consumption and solves the problems of dust, noise and sewage in the construction site.

The standardization rate and commercialization degree of American housing almost reached100%; 80% houses in Switzerland are built on the basis of passing part; The degree of industrialization in France is also very high, mainly using prestressed concrete frame assembly system, and the assembly rate of this system can reach 80%. Compared with the traditional cast-in-place construction method, the construction template is reduced by 85%, the scaffold consumption is reduced by 50%, the energy is saved by 70%, the water is saved by 80%, the steel is saved by 20%, and the benefits of saving land and stones are considerable. At the same time, construction waste can be reduced by 83% and saved by 20%. From the above data, we can have a preliminary understanding of the efficiency of industrialization.

In terms of resource reuse, the recycling rate of Japan, South Korea and other countries reached 90% more than a decade ago. So far, the proportion of buildings in China is actually less than 5%.

Why does information technology and building industrialization become a "pair"

With the rapid development of information technology, along with the mobile Internet, the application of new technologies such as big data, digital construction, cloud computing and artificial intelligence has been widely discussed. First of all, this has brought great impact to the traditional way of thinking, especially when people are changing from the original causal thinking logic to the relevant thinking logic.

Architecture is no longer just to solve the housing problem. Green development, ecological protection and energy accumulation have been integrated into people's demand for architecture, so the connotation of the original architecture has also changed. In order to improve the quality and efficiency of the building itself, it is necessary to re-evaluate and re-integrate the existing architectural design process, production and construction process and operation management process.

In the process of changing from causal logic to relational logic, architects have found a consistent choice in creating the ideal of "better living", and information technology is organically combined with building industrialization.

In the past ten years, the construction industry has developed rapidly under the impetus of new technologies. Not only Britain, but also all countries have launched corresponding research and some policy orientations in the new information age. In particular, Germany put forward the concept of Industry 4.0 a few years ago, making the new industrialization characterized by information technology become the focus of the whole global competitiveness in the future.

Implementing the strategy of informationization to promote industrialization in large-scale labor services is a breakthrough in transforming and upgrading the traditional construction industry, and the only way for China's architecture to move from a "building power" to a "building power".

How does information technology accompany the development of building industrialization

The core of industrialization is an organization and management model, which is a whole system, characterized by division of labor and cooperation, optimal allocation of resources and optimization of procedures. Use the most economical production factors to complete in the shortest time. A clear division of labor in industrialization is conducive to the improvement of specialization and production efficiency.

Information technology provides a platform and possibility for the interaction and cooperation of multiple systems needed for building development. Information technology is a powerful driving force to promote the new construction industrialization.

At present, building industrialization has gone through two stages of development. The first stage has three characteristics: standardization and modularization of components; Mechanization of construction; Field assembly, detailed division of labor and programming.

With the promotion of information technology, building industrialization has entered the second stage, which is characterized by using big data architecture to realize intelligent decision-making applications in the Internet environment and supporting front-end visualization and simulation, which will provide efficient and rich solutions for building industrialization that could not be solved in the past. The problems in the first stage, such as the contradiction between the uniqueness of building components and the standardization of industrial production, the contradiction between architectural design and component manufacturing, and the contradiction between architectural design and construction, can be effectively solved in the second stage of building industrialization.

One of the main characteristics of the second stage of building industrialization is to promote industrialization by informationization, which can greatly improve the benefits from the stages of design, budget, construction and operation and maintenance. It has the following characteristics:

1. It is different from the concept of industrialization in the past to build a system in the design process, realize component design, socialized manufacturing and procurement, and use Internet technology.

2. Combination of industrialization and personalization: mass production and personalized customization are combined to realize rapid mass customization. This is the characteristic of the information age.

3. Integrate multidisciplinary advanced technologies into architectural design and construction, realize technology integration and overcome traditional industrialization problems.

The second stage of building industrialization development must rely on the support of big data information platform. At present, there are few similar systems on the market.

Development trend of building industrialization in the future

The direction of industrialization 4.0 is very clear. The new era put forward the strategy of information age and new hardware age, and China also mentioned "internet plus". The direction of Industry 4.0 is very precise, that is, to take advantage of the German manufacturing industry and continue to maintain the advantages of national development in the new era.

Industry 4.0 includes the transformation from centralized control to decentralized enhanced control, which is of great significance to the construction industry. The mass purchase and transportation of buildings has been subverted in Industry 4.0, just like the largest taxi company has no car, and the largest retailer has no physical store and no product inventory. So what is the future of the construction industry? In fact, our information and network era has also brought revolutionary changes. Digitizing the whole product life cycle and manufacturing process and modular integration based on information and communication technology will form a highly flexible and digital production mode of products and services. In this mode, BIM is the core technology platform. Therefore, seeing the correlation between informatization and industrialization, BIM is an important technology and technology platform to promote the development of new industrialization and informatization in construction industry. BIM technology is a subversive revolution to promote architecture.

"BIM+" era of architecture

Internet plus can be called "BIM+" in the construction industry. On the BIM technology platform, many things can be loaded. At present, the field of BIM has been greatly promoted, and the version of BIM standard is constantly updated. China still has a lot of work to do.

The arrival of the "BIM+" era combines the Internet, cloud computing, big data, 3D printing, VR/AR technology and 3D GIS, and has made many extensions from the BIM technology platform. For example, in the integration of 3D GIS and BIM, extending to the city level, smart cities and digital cities can get through the platform and design, build and operate together efficiently.

BIM+VR can also solve many problems that were originally difficult to solve, such as what you see, some problems that are difficult to control in engineering. In fact, VR provides many new technical means. There is a saying that the combination of digital design platform and VR will become the core competitiveness of our pan-design enterprises in the future.

With the rapid development of VR, AR is not only in the virtual environment, but also superimposed in the real environment. The combination of BIM and AR also has great development space, which brings many possibilities for our urban construction, architectural design and construction.

In terms of BIM+3D printing and BIM+ mechanical arm construction, the mechanical arm is now relatively mature in hardware. Now the key is whether these are really used in the field of engineering, design and construction, which provides us architects with a lot of imagination. Some buildings with special shapes, which were difficult to build in the past, can now be realized by BIM and 3D, BIM and robotic arm manufacturing. It turns out that some things designed with nonlinearity may also need to be built and realized with 3D technology and robotic arms.

Transformation and upgrading of architecture in China

If China is to move from a big building country to a powerful building country in the world, extensive China architecture needs upgrading and transformation, and industrialization and informatization are the core. There are three main points:

1, fine construction, that is, how to build with low energy consumption and high efficiency.

2. The key to intelligence is that the building should be considered by users. Many things, from design, construction, operation to supervision, should be able to run through wisdom from beginning to end.

3. The building should be oriented to greening.
