Building Information ModelIs a new tool for Architecture, Engineering, and civil engineering.. The term building information model or building information model was created by Autodesk.It is used to describe computer-aided design that focuses on 3D graphics, object orientation, and architecture.. At the beginning, this concept was introduced to the public by Jerry laiserin to promote the technologies provided by Autodesk, benteli system software, and graphisoft.
1. Brief description of Bim (
Building Information Modeling) Technology was first proposed by Autodesk in 2002 and has been widely recognized by the industry worldwide,
It can help achieve the integration of Building Information,
From the design, construction and operation of a building to the end of the whole life cycle of the building,
All kinds of information are always integrated with a three-dimensional model information database,
Design Team, construction unit, facility operation department, owners and other personnel can work collaboratively Based on Bim,
Effectively improve work efficiency, save resources, reduce costs, and achieve sustainable development. Core of Bim
By establishing a virtual 3D model of building engineering, using digital technology,
Provide a complete and realistic building engineering information database for this model.. This information library
It not only contains geometric information, professional attributes, and status information describing building components, Including
Status information of non-component objects (such as space and motion behavior).
With the help of this three-dimensional model that contains the construction engineering information, the information integration degree of the construction engineering is greatly improved.,
This provides a platform for project information exchange and sharing for stakeholders of the T-way construction project.. BIM has the following features:
It can be applied not only in the design, but also in the whole life cycle of the construction project.The design with BIM is a digital design. The Bim database is dynamic and constantly updated, enriched and enriched in the application process. It provides a collaborative platform for project participants. China's bim standards are under research and development, and the research team has achieved initial results. Building Information modeling is a data-based tool used in engineering design, construction, and management. It integrates the Data and Information Model of buildings, share and transmit the whole life cycle of project planning, operation and maintenance so that engineers and technicians can correctly understand and efficiently respond to various construction information, it provides the foundation for collaborative work for the design team and Construction and Operation Entities, and plays an important role in improving production efficiency, saving costs, and shortening the construction period. Here we reference the definition of Bim in the U.S. National Bim standard (nbims), which consists of three parts:
(1) BIM is a digital expression of physical and functional characteristics of a facility (Construction Project);
(2) BIM is a shared knowledge resource and information about the facility.,
Process that provides a reliable basis for all decision-making throughout the life cycle from concept to demolition of the facility;
(3) different stakeholders insert, extract, update and modify information in BIM at different stages of the facility,
Collaborative operations to support and reflect their respective responsibilities. Features Bim has the following four features: Visual visualization is the form of "WYSIWYG". For the construction industry, the role of visualization in the construction industry is very large, for example, the often obtained construction drawings only show the information of each component on the drawings by drawing lines. However, the real construction form requires the construction industry practitioners to imagine it on their own. BIM provides a visual way of thinking, allowing people to form a three-dimensional physical image of the past line components in front of people; now the construction industry also has a design aspect. however, this kind of information does not include the size, position, and color of components, and lacks the interaction and feedback between different components. The visualization mentioned by BLM is a kind of visualization that can form interaction and feedback between the same components. Because the whole process is visualized, the visual results can not only be generated by presentation and report, more importantly, communication, discussion, and decision-making during project design, construction, and operation are all performed in a visual manner. Coordination and coordination are the key content in the construction industry. Both the construction unit and the owner and the design unit are working on coordination and coordination. Once a problem is encountered during the implementation of the project, relevant persons should be organized to hold a coordination meeting to find out the causes and solutions of the various construction problems. then, make changes and take appropriate remedial measures to solve the problem. During the design, communication between professional designers is often not in place, resulting in a collision problem between various specialties. For example, when the pipelines in HVAC and other major are arranged, the construction drawings are respectively drawn on their respective construction drawing sheets. During the actual construction process, it may be better that the structural design of beams and other components will hinder the arrangement of pipelines here. Coordination of collision problems like this can only be solved after the problem arises. The Bim Coordination Service can help solve this problem. That is to say, the BIM building information model can coordinate the Collision Problems of various major in the early stage of building construction, generate coordination data, and provide it. Of course, the coordination function of Bim is not only to solve the collision problem between different majors, it can also solve problems such as coordination of elevator shaft layout and other design layout and clearance requirements, coordination of fire partition and other design layout, coordination of Underground Drainage layout and other design layout. Simulation simulation is not only designed to simulate a building model, but also to simulate things that cannot be operated in the real world. In the design phase, bim can simulate some things that need to be simulated in the design. for example, energy-saving simulation, emergency evacuation simulation, Rizhao simulation, and thermal energy conduction simulation. 4D simulation can be performed during the bidding and construction phases (the development time of the 3D model additional project ). that is, the actual construction is simulated according to the construction organization design, so as to determine a reasonable construction scheme to guide the construction. At the same time, it can also carry out 5d simulation (based on the 4D model and Cost Control) to achieve cost control. In the later stage, it can simulate the handling methods of daily emergencies, for example, earthquake escape simulation and fire evacuation simulation. Optimization in fact, the entire design, construction, and operation process is a process of continuous optimization. Of course, there is no substantial link between optimization and Bim, but it can be better optimized on the basis of Bim. Optimization is constrained by three factors: information, complexity, and time. Without accurate information and reasonable optimization results, the BIM model provides the actual existing information of the building, including geometric information, physical information, and rule information, it also provides the actual existence information after the building changes. When the complexity is high, the participants cannot grasp all the information, and they must use certain scientific and equipment help. Most of the complexity of modern buildings exceeds the capability limit of participants. Bim and its supporting optimization tools provide the possibility to optimize complex projects. Common Software Bim modeling software: (1) Autodesk
