BIM causes engineering construction management change

10 years ago, Autodesk company put forward the concept of BIM (building information model), and since then BIM has been familiar and applied by more and more people in the field of engineering construction in China. On August 30th, at the awarding ceremony of the 20 12 Creative Cup-BIM Design Competition held in Beijing, Dai, a master of engineering survey in China and president of Fujian Architectural Design and Research Institute, said that BIM technology, like CAD technology more than 20 years ago, will bring revolutionary changes to the engineering design industry.

The reason why BIM has such a great influence is that it parameterizes and digitizes building information through digital modeling, forming a visual model as a platform for engineering construction units, design units, construction enterprises and property maintenance units to enjoy information in the whole life cycle of a building project.

This application is in full swing.

From the National Stadium Bird's Nest in Beijing to the Center Building in Shanghai, and then to the "Little Man's Waist" in Guangzhou ... For decades, a large number of new technologies, new materials and new processes have been introduced and applied in the field of engineering construction in China, and a number of landmark buildings have been built. But as far as the whole industry is concerned, extensive management, high emission and high consumption, low productivity and waste of resources still restrict the development of the whole industry.

Experts generally believe that in order to develop the construction industry, it is necessary to achieve industrial upgrading, comprehensive optimization, technological progress and sustainable development, and BIM will be the key to promote the transformation and technological leap of the whole construction industry.

Dai introduced at the meeting that the BIM application process of Fujian Architectural Design and Research Institute can be basically divided into three stages:

The first stage is the enlightenment learning stage. "Our institute began to learn BIM technology in 2003. After Autodesk's Revit3CAD software was introduced in 2005, we introduced it to professional technicians through lectures and other forms. "

The second stage is the stage of practical exploration. "In 2009, we undertook the commercial plaza project of Fuzhou Wanda Financial Street. The project has a large scale and a short construction period. Completed the project construction drawing covering an area of 400,000 square meters within 3 months. " In order to ensure that the construction period is not delayed and the design quality is guaranteed, Fujian Architectural Design and Research Institute has transferred more than 40 technical backbones to form a project team. The project team used Revit 3D CAD software to complete the 3D design of the project. The whole design process has gone through three collision checks, and more than 20,000 mistakes such as collision, cutting and leakage have been eliminated.

For Fujian Architectural Design and Research Institute, the greater gain is that they have experienced a group of three-dimensional design technical backbones through engineering practice, which has increased their confidence in popularizing and applying BIM technology.

The third stage is the application development stage. From 20 10, Fujian Architectural Design and Research Institute stipulated in the annual responsibility index that all professional design institutes must use BIM technology to complete more than three engineering projects. In 20 12, Fujian architectural design and research institute established BIM application research center, and BIM construction drawing expanded from single architectural specialty to full professional drawing, from pipeline collision detection to green ecological analysis, lighting and ventilation analysis, solar radiation analysis, biological environment analysis, building energy saving and emission reduction analysis, forming a documented, standardized and standardized design process, and formulating BIM collaborative design drawing and drawing standards.

Dai concluded that leaders' attention, system in place, personnel training, incentive mechanism, standardization construction, willingness to invest in scientific research and equipment are the six guarantees for Fujian Architectural Design and Research Institute to successfully promote and apply BIM.

"The application of BIM technology enables the project designer to make a good prediction on the sustainability of the project, that is, before the project is implemented, to predict whether the project is really green and energy-saving. Shanghai Tower Project is such a project. In addition, BIM technology is also applied to the Olympic Park Watchtower, Heixiazi Island Botanical Garden, Longyan Finance and Business Center, Heilongjiang Wudalianchi Volcano Museum, Ahai Hydropower Station, Quyang Jinyu Cement Plant, Expo Substation and other projects. It can be seen that the demand for BIM technology is obvious whether it is a project with relatively complex shape and structure, or an infrastructure or industrial facility project. " Wei Bode, senior vice president of Autodesk and president of Asia Pacific and emerging markets, introduced.

Promote the construction of standards

"BIM is our common language. Although we all speak different mother tongues, BIM is a common language in engineering, architecture and construction. " Robert E.Middlebrooks, strategy and industry relations manager of Autodesk's construction industry and a member of the American Institute of Architects, told reporters.

BIM is a direction of information technology development in the field of construction, which may lead to a complete change in the whole construction industry. So, what conditions need to be met to truly popularize BIM?

The first is to establish a standard system of BIM. The function of BIM is to make all aspects of information of construction projects unimpeded. This requires a baseline of information integration, sharing and cooperation at all stages of a building's life cycle of decades and hundreds of years. This is the BIM standard. Establishing standards is one of the most important conditions for implementing BIM. Only when the technology, implementation framework and enterprise implementation rules are fully established can BIM be truly popularized.

In order to promote the practical application of BIM in China and improve the informatization level of China's construction industry, Tsinghua University Institute of Software started the research on BIM standards in China as early as March 2009.

At the beginning of this year, Professor Tsinghua University Gu Ming said at the strategic cooperation meeting between Tsinghua University and Autodesk, "At present, the promotion and application of BIM is in a critical period, that is, the transition from the project-level application of BIM to the enterprise-level application of BIM, which is a key step for BIM to finally move towards the industry-level comprehensive application. In this key process, the establishment of standards is the core work, because the application of BIM has the characteristics of cross-industry, multi-field and full cycle, which makes the study of CBIMS (China Building Information Model Standard) of special significance and considerable difficulty. Tsinghua University will also cooperate with the efforts of Industry-University-Research at home and abroad to complete the research and formulation of China BIM standards, promote the progress of informatization in China's construction industry, and help the industrial upgrading of the construction industry. "

It is understood that according to the requirements of the Notice of the Ministry of Housing and Urban-Rural Development on Printing and Distributing the Revision Plan of Engineering Construction Standards and Specifications for 20 12 years, the national standards "Unified Standards for the Application of Building Engineering Information Models" and "Storage Standards for Building Engineering Information Models" have been included in the formulation plan. In addition, the national standard "Unified Standard for Application of Building Engineering Information Model" approved by the Ministry of Housing and Urban-Rural Development and the online discussion forum authorized by China BIM Development Alliance-"Suggestions on the BIM Standard Thousand Talents Participation Plan Network in China" have been officially launched. With the gradual progress of all work, we can see that the formulation of BIM standards in China has been advancing.

Application status of BIM in various countries

Britain will change the process of government construction projects, hoping to achieve higher efficiency and lower cost through BIM. According to the construction strategy announced by the Cabinet Office of the government in May, 20 1 1, they will work with various professional groups in the industry to formulate standards, so that the entire industrial chain of the construction industry can achieve better cooperation by using BIM technology.

South Korea is very leading in the application of BIM technology, and many government departments are committed to formulating BIM standards, such as the Korea Government Supply Bureau and the Korea Ministry of Land, Infrastructure and Oceans. The Ministry of Land, Infrastructure and Oceans of Korea formulated the BIM application guide in the fields of architecture and civil engineering on June 20 10. This guide explains in detail the methods and elements that developers, architects and engineers must pay attention to when adopting BIM technology.

BCA hopes that BIM technology will be widely used by more than 80% construction enterprises before 20 15. Government departments will take the lead in applying BIM technology, and it is planned that from next year, all new projects must apply BIM technology. In addition, the Singapore Architectural Engineering Bureau has set up a BIM fund, hoping to encourage enterprises to introduce BIM technology into construction projects.

The United States is one of the first countries to apply BIM. Many departments of the US government have begun to use BIM to assist their work. The following are three organizations that should use BIM: General Services Administration (GSA) is an organization that serves American citizens; The US Army Corps of Engineers (USACE) is committed to strengthening US national defense and is responsible for building and maintaining US military facilities; In February 2007, the National Institute of Building Research issued the first part of the national BIM standard.

In 2009, the Australian government issued the National Digital Model Guide, hoping to promote the application of BIM technology in all stages of construction, so as to improve the cooperation level and implementation efficiency of construction projects.

Finnish Senate Real Estate Company is the largest government agency in Finland, responsible for the management and transfer of Finnish real estate. Senate Real Estate issued a set of BIM requirements for architectural design in 2007, which put forward comprehensive requirements for all project participants.

Norway Norwegian Public Construction Bureau is an organization that provides consulting services on construction and property management for the Norwegian government. 20 1 1.2 The Norwegian Public Buildings Department issued a BIM manual version, which contains information about the requirements of BIM, the reference and use of BIM in various construction stages, and the guidance on how to build a good BIM model.
