I. Overview of BIM technology
1.BIM technical meaning
BIM technology is a new technology based on digital information and computer technology, which is applied to project design, management, guidance, operation and maintenance. BIM technology is based on three-dimensional technology and digital information technology, which realizes the integration of all stages of engineering construction and lays a solid technical foundation for improving the efficiency of modern buildings. Simply put, it is to build a virtual building with the help of digital technology, form a perfect information database, and play its benefits in modern urban construction.
2.2 application direction. BIM technology
First of all, BIM technology can be used in the field of construction engineering management. By designing for different objects, combining the geographical location information and basic description information of buildings to define building attributes, and by comparing the engineering data information of multiple projects, the corresponding building management scheme can be determined. Secondly, BIM technology can be used in engineering planning. Specifically, at present, many buildings have certain regulations on environmental protection and energy consumption, which requires BIM technology to integrate and analyze the overall control parameters as the main basis for planning and design.
In addition, BIM technology can also be used in architectural design. The implementation stage of architectural design involves many professional fields such as architecture, structure, water heating, electricity and so on. Relying on the building information model, it can provide the most original data information for construction drawing design and construction operation management, thus ensuring that the performance of the construction project is highly consistent with the actual building demand. In a sense, it can be used as an architectural evaluation index to guide the architectural design process.
Second, the application of BIM technology in modern urban construction
With the development and progress of modern cities, the performance requirements of urban buildings are getting higher and higher, and they are gradually developing and progressing towards high quality, low carbon, informationization, digitalization, intelligence and environmental protection. As a new architectural concept and technology, BIM technology is rapidly integrated into the practice of modern urban construction with its unique advantages, and presents diversified characteristics. Therefore, this paper mainly discusses the advantages of BIM technology in the following aspects:
The application of 1 BIM technology in urban railway bridge engineering
Railway bridge engineering is an important part of urban construction system. The application of BIM technology in railway bridges is mainly reflected in the design of railway bridges, the manufacture of steel beams and the management of construction projects. The application of (1)BIM technology in railway bridge design has eliminated the traditional design mode. Taking the establishment of railway bridge component library as an example, BIM technology can scientifically handle the model relationship between bridge structure and line, surveying and mapping and geology, and can realize the formulation of BIM collaborative design scheme according to different railway bridge projects.
Application of BIM technology in steel beam manufacturing With the help of numerical control code, digital assembly of components can reduce the processing flow and improve the processing efficiency. For example, combined with the bar management of BIM model, the specific attributes of bars can be obtained through bar codes, which can lay an information foundation for assembly construction; With the help of BIM technology, the best consumption scheme of plate and nesting can be determined, thus improving the utilization rate of plate and reducing the production cost; BIM technology can also promote the development of railway bridge manufacturing integration. (3) Application of BIM technology in engineering management can be used to collect and sort out railway engineering project management information, thus forming a multidimensional database, and applying these data to construction engineering management, realizing real-time * * * shared management, and making construction engineering management develop and progress in a refined direction. For example, BIM visual disclosure can ensure handover quality, and dynamic progress management can scientifically handle the relationship between construction tasks and construction progress.
Application of 2.2. Application of BIM technology in urban residential projects
With the concept of green building being recognized by more and more people, BIM technology has been widely used in modern urban housing projects. Mainly reflected in: (1) design stage. Three-dimensional model is established by BIM, so that owners, architects and supervisors can understand the building structure more intuitively, avoid all kinds of building disputes, find defects and deficiencies in time, and adjust and improve the design scheme. (2) Construction stage. With the help of BIM technology, builders can better understand the designer's intention, and then carry out the construction more smoothly and avoid the waste of construction materials. With the help of virtual simulation information, they can optimize the allocation of human resources, financial resources and material resources, thus saving housing costs.
(3) delivery stage. At present, there are many shortcomings in China's property management, especially in the context of the separation of developers and property, it is easy to lose a lot of drawings and materials, which will bring a lot of inconvenience to property management. However, if the BIM model is handed over to the property management department in the delivery process, both pipeline maintenance and line laying can be obtained from the BIM model, so that the work can be carried out more pertinently, which is also the key to promoting the quality and efficiency of property management.
Application of 3.3. BIM technology in urban sustainable development and construction
Modern city construction adheres to Scientific Outlook on Development, and the concept of sustainable development city emerges as the times require. The so-called sustainable development is to scientifically handle the relationship between resources, ecology, environment and urban development in the process of urban construction, and choose a more environmentally friendly way to carry out urban construction activities. Specifically, it mainly includes living in harmony with the surrounding environment and realizing ecological protection; There should be no environmental pollution in the process of urban construction, and the way of good lighting, good ventilation and solar energy utilization should be chosen to realize the optimization and adjustment of architectural design scheme; Realize the optimal allocation of urban resources through science and technology, and achieve the effect of recycling.
In order to promote the process of sustainable urban construction, BIM technology can make outstanding contributions in the following aspects: using BIM technology to obtain more comprehensive urban building information, combining with sustainable development standards and norms, evaluating and evaluating the surrounding environment of buildings, thus showing the ecological benefits of sustainable urban construction planning; In the process of construction, BIM technology is used to optimize the urban construction process and promote the development of the construction process in a more ideal way; With the help of the application of BIM technology in construction engineering, we can establish the awareness of recycling, realize the demonstration of resource saving in modern urban construction, and enhance the application benefit of practical technology.
Thirdly, the application strategy of BIM technology in modern urban construction.
Based on the current practice of BIM technology applied to modern urban construction, its defects and deficiencies are mainly reflected in the following aspects: (1) At present, the application foundation of BIM technology in China is relatively poor. Although many designers have heard of BIM technology, few people can see the benefits of BIM application in the whole interest chain of the construction industry, which leads to its narrow application scope in actual urban construction, mainly in a few high-rise buildings and large public buildings.
(2) Lack of professional BIM design talents. No matter from the architect's knowledge structure or the comprehensive ability of the building, the current design team is difficult to meet the actual design needs. They not only need to change the traditional design concept, but also need to actively learn the theory and practical experience of BIM technology, so as to promote the overall improvement of the quality of architectural works.
(3) The theoretical system of BIM technology is not perfect, and there are still many links that need to be broken through, which is also the bottleneck that affects the application effect of BIM technology at present.
In view of the above problems, the following work can be done: (1) Attach great importance to the publicity and education of BIM technology theory, strengthen the publicity of the construction industry, let more actors realize the advantages of applying BIM technology, and correctly understand the relationship between BIM application and modern urban architecture, so as to create a good atmosphere for the application of BIM technology. (2) Attach great importance to the construction of specialized teams and strengthen BIM theory and skills training. (3) Encourage more scholars and experts to pay attention to the application research of BIM technology in modern urban construction, strengthen the protection of intellectual property rights, actively learn from the application experience and lessons of developed countries, and promote the perfection and perfection of the theoretical system of BIM technology.
Four. conclusion
To sum up, BIM technology can not only promote the transformation of urban construction mode and concept, but also play an active role in improving the ecological and economic benefits of urban construction. Although the benefits of using BIM technology in the process of modern urban construction in China have not been fully realized, there are still many shortcomings and defects in many aspects, but I believe that with the continuous improvement of theoretical system in this area, the continuous consolidation of human resources team and the introduction of national policies, China's modern urban construction will definitely develop and progress in the direction of digitalization.
