What is BIM and what is its specific function?

BIM technology is a powerful technical platform for processing basic data, which has the characteristics of "timeliness, accuracy, correspondence and traceability". While improving the management and control ability, improve the fine management ability of projects and building materials. Reducing the waste of building materials caused by design or construction errors is also the best way to reduce energy consumption.

BIM has six technical characteristics, including: visibility-two dimensions are plane and three dimensions are space; Coordination-the coordination of time cost, labor cost and error cost; Simulation-predict the possible problems of the project in advance; Optimization-optimization of information, complexity and time; Information-transmitting information completely and effectively at all stages; Drawing-Automatically generate elevation and section views according to the plane.

BIM also has eight design advantages: first, three-dimensional design, split design of all parts of the project, and scheme design of particularly complex projects around the world; The second is visual design, indoor and outdoor visual design, which is convenient for owners to make decisions and reduce the amount of rework; Third, collaborative design, multi-discipline design on the same platform, to achieve efficient collaborative design; Fourth, it is convenient to modify, modify at one place, update everywhere, and integrate calculation and drawing; Fifth, pipeline detection, through the collision detection of electromechanical specialty, to solve the fight of electromechanical pipeline; Sixth, improve the quality, adopt efficient collaborative design, reduce errors and omissions, and improve the quality of drawings; Seventh, automatic statistics, which can automatically generate the bill of materials for automatic statistics of engineering quantities; The eighth is energy-saving design, which supports the sustainable, green, energy-saving and environmental protection design of the whole project through software.

BIM technology has improved the energy-saving level of the construction industry. Green building is an energy-saving building, and its energy-saving is reflected in all aspects, from design, building materials, construction to operation and maintenance. , we must highlight the green concept and reflect the relevant national policies and standards. In this series of processes, BIM technology is very important to achieve accuracy.

The main reasons why the modes of design, construction and operation are not enjoyed are: different division of labor, different goals, different resources, different qualities, different technologies and different experiences. However, some BIM technology experts and BIM technology research institutions believe that BIM is a technology, an idea and a platform. There is no free lunch in the world, and you reap what you sow; BIM technology emphasizes information sharing, data storage and convenient calling. BIM is a process of continuous improvement only when it is in progress and not completed. BIM technology can be used not only in design, construction and operation, but also in management and operation.

In the construction industry of China, BIM technology is a revolution in the construction industry, which will inevitably lead to a subversive revolution in the construction industry from technical means to business model. In the future, compound talents who understand design, construction, cost and BIM will be in short supply in the market.

I hope I can help you, thank you for your adoption!
