What work can BIM be applied to?

BIM is the digital expression of project information, the direct application of digital technology in the construction industry, and represents the new direction of information technology application in the construction industry in China. BIM involves the whole practice process of all links in the whole life cycle of a building project, but it is not limited to the whole practice process to realize its value, but can be realized through the value of engineering design first and stage. With the rapid development of China's economy and the increasingly serious energy problems, building energy-saving design has become more and more important. In the near future, the green building design technology using BIM and building energy consumption analysis will be more and more perfect and mature. Only by studying the characteristics of China, combining with reality, practicing hard and being brave in exploration can we embark on a new road of development as soon as possible. Overview of BIM technology 1. What is BIM? BIM refers to the origin of Building Information Model (BIM). The theoretical basis of BIM mainly comes from the idea of Computer Integrated Manufacturing System (CIMS) which integrates CAD and CAM in manufacturing industry, and the product information model based on product data management PDM and STEP standards. 2.2 What problems have been solved? BIM？ BIM is a digital expression of physical and functional characteristics of engineering project facilities. A perfect information model, which can connect the data, processes and resources in different stages of the life cycle of a construction project, is a complete description of the engineering object and can be widely used by all participants in the construction project. BIM has a single engineering data source, which can solve the problem of consistency and global sharing of distributed and heterogeneous engineering data, and support the creation, management and sharing of dynamic engineering information in the life cycle of construction projects. The characteristics of 3.3. BIM 1) model information integrity. In addition to describing the three-dimensional geometric information and topological relationship of engineering objects, it also includes complete engineering information description, such as object name, structural type, building materials, engineering performance and other design information. Construction progress, schedule, cost, quality and construction information such as manpower, machinery and material resources; Maintenance information such as engineering safety performance and material durability; Engineering logic relationship between objects, etc. 2) Relevance of model information The objects in the model are identifiable and relevant, and the system can make statistics and analysis on the model information and generate corresponding graphs and documents. If an object in the model changes, all related objects will be updated to maintain the integrity and robustness of the model. 3) Consistency of model information The model information is consistent in different stages of the building life cycle, and the same information does not need to be input repeatedly. The information model can evolve automatically, and the model objects can be simply modified and expanded in different stages without re-creation, thus avoiding the error of inconsistent information. The value and function of 4.4. BIM 1) solves the bottleneck problem of informatization in the current construction field and establishes a single engineering data source; Promote the application of modern CAD technology; Promote the life cycle management of buildings, realize the integrated management of engineering performance, quality, safety, progress and cost at all stages of the life cycle of buildings, and analyze, predict and control the total cost, energy consumption and environmental impact of the life cycle of construction projects. 2) Used in engineering design to realize three-dimensional design; Realize the information sharing between different professional designs; Realize virtual design and intelligent design, realize design collision detection, energy consumption analysis, cost prediction and so on. 3) IPD (Integrated Project Delivery) management is used for construction and management to realize the integration of project delivery; Realize the dynamics, integration and visualization of 4D construction management: connect the three-dimensional models of buildings and construction sites with the construction progress, and integrate them with construction resources and site layout information to establish a 4D construction information model. Realize the dynamic integrated management of project schedule, manpower, materials, equipment, cost and site layout and the visual simulation of construction process in the construction stage of construction projects. Realize the collaborative work of all project participants: All project participants can enjoy information, submit, review, approve and use documents, drawings and videos based on the network. All participants in the project work together through the network, negotiate and coordinate the project, and realize the management and monitoring of construction quality, safety, cost and progress. Realization of virtual construction: the construction process is carried out on the computer, and the virtual model can predict the potential problems such as the function and constructability of the project before the actual construction, including construction method experiment, construction process simulation and construction scheme optimization.
