The Director of the Department of Engineering Quality and Safety Supervision of the Ministry of Housing and Urban-Rural Development (MOHURD) explained BIM. She said: BIM technology is a data-based tool applied to engineering design and construction management, integrating various project-related information through parametric modeling, and *** enjoying and transmitting it during the whole life cycle process of project planning, operation and maintenance, so as to enable engineers and technicians to make a correct understanding of various construction information and respond to it efficiently, and to provide a basis for collaborative work for the design team as well as for the construction bodies of all parties including the building operation units, playing an important role in improving productivity, saving costs and shortening the construction period. It provides the basis for design teams and all construction entities, including building operation units, to work together, and plays an important role in improving productivity, saving costs and shortening construction periods.
BIM is known as Building Information Modeling (BIM) in English, which is consistently translated as Building Information Modeling (BIM) in Chinese.
Since the domestic "Building Information Modeling Application Standard" is still in the preparation stage, here temporarily cited the U.S. National BIM Standard (NBIMS) definition of BIM, the definition consists of three parts:
1. BIM is a facility (construction project) physical and functional characteristics of the digital expression;
2. BIM is a **** enjoyment of the knowledge resource, a process of sharing information about this facility to provide a reliable basis for all decisions throughout the life cycle of the facility, from construction to demolition;
3. Collaborative operations in which different stakeholders work together by inserting, extracting, updating, and modifying information in the BIM during different phases of the project to support and reflect their respective responsibilities.
Expansion
The storage of data of building information in BIM is mainly based on various digital technologies so that this digital information model can be used as a basis for various building projects to go for various related tasks [1].
Building information modeling is not simply the integration of digital information, but also an application of digital information and can be used for the design, construction, and management of digital methods, which support an integrated management environment for construction projects, which can enable construction projects to significantly improve the efficiency and significantly reduce the risk throughout its process.
The building information model enables integrated management throughout the entire lifecycle of a building project, so the model includes both the information model of the building and the model of the management behavior of the building project. The information model of the building and the management behavior model of the construction project are perfectly combined. Therefore, within a certain range, the building information model can simulate the actual construction behavior of the building project, such as: sunshine of the building, the heat transfer state of the external maintenance structure, and so on.
Currently, the construction industry has stepped into the introduction and popularization of computer-aided technology, such as the introduction of CAD, which solves the problem of computer-aided drafting. And this introduction by the construction industry insiders vigorously welcome, well adapted to the needs of the construction market, designers no longer use manual drawing, but also to solve the drawbacks of manual drawing and modification of the error prone. In the "map" is no longer the backward will be the professional sulfuric acid drawings overlap the map. These CAD graphics can be utilized in the various professions in each other. Give people a convenient way to work, reduce labor intensity, so computer-aided drafting has been warmly welcomed by the people. Other aspects of the characteristics, will not be listed here.
