BIM is a professional BIM circle
.
BIM is a necessary professional skill for engineers
.
How much do you know about BIM? In recent years, the Ministry of urban and rural development has never stopped issuing BIM related standards, BIM is in the stage of rapid development, so for the construction party, what are the main application points of BIM? Let’s have a look
.
The BIM application of the construction party requires the construction party to be the final implementer of the project and the creator of the completed model
.
The construction enterprise focuses on the site implementation, how to combine the BIM with the project, how to improve the efficiency and reduce the cost ▶ Understanding the design intention and visualizing the joint review of design drawings can help the construction personnel to interpret the engineering information faster and better, find out the design errors as soon as possible and conduct design liaison in time; ▶ Reduce the construction risk, use the model for intuitive “pre construction”, predict the construction difficulties, eliminate the uncertainty and unpredictability of construction to a greater extent, and ensure the feasibility, safety, rationality and optimization of construction technical measures; ▶ Grasp the construction details, carry out the construction deepening design on the basis of the model provided by the designer, solve the detailed problems and construction details that are not reflected in the design information, and conduct the technical disclosure to the site construction workers more intuitively and realistically; ▶ More factory prefabrication provides the most detailed processing details for component processing to reduce field operation and ensure quality; ▶ Provide convenient management means, use the model to check the load in the construction process, schedule material control, construction quality inspection, etc

According to statistics, the global construction industry generally has the problem of low production efficiency, in which 30% of the construction process needs to be reworked, 60% of the labor force is wasted, and 10% of the loss comes from the waste of materials
.
The huge construction industry is fragmented by the separation of a large number of building information, design errors and changes, and the repeated construction process
.
The virtual building model created by BIM application system is a database containing all the information of the building, so 3D building model can be combined with time and cost, so as to carry out intuitive construction management for the construction project
.
BIM Technology in the construction of building structure mainly includes three-dimensional collision inspection, calculation technology, virtual construction and 4D construction simulation technology
.
The specific applications are as follows: 1
.
Scheme comparison and optimization design
.
Because BIM is a parametric design, engineers can quickly generate a variety of construction scheme models, submit and compare them, and modify them conveniently and quickly
.
At the same time, because BIM carries a lot of building information, designers can easily carry out various energy consumption, lighting, wind and other analysis, and constantly optimize the scheme to meet the needs of owners to the maximum extent
.

.
Collision check, reduce rework
.
The most intuitive feature of BIM is three-dimensional visualization
.
Using the three-dimensional technology of BIM, collision check can be carried out in the early stage, engineering design can be optimized, error loss and rework that may exist in the construction stage can be reduced, clearance can be optimized, and pipeline layout scheme can be optimized
.
Finally, construction personnel can use the three-dimensional pipeline scheme after collision optimization to carry out construction The construction quality is improved by construction disclosure and construction simulation, and the ability to communicate with the owner is also improved
.

.
Deepening the construction drawing and generating high-quality design and construction drawings based on BIM model is the fundamental purpose of BIM Technology in the project design stage, which lays the foundation for the follow-up high-quality construction, supervision and operation maintenance
.
In the process of building BIM model, a lot of equipment reference information is input, including component, equipment, pipeline material, model, installation height, installation mode and so on
.
Therefore, it is different from using two-dimensional plane for pipeline synthesis, and there is no need to find the required information from design instructions, equipment manuals and other documents
.

.
Virtual construction, effective coordination of three-dimensional visualization function, plus time dimension, can carry out virtual construction
.
Compare the construction plan with the actual progress intuitively and quickly anytime and anywhere, and carry out effective coordination at the same time
.
The construction party, the supervisor, and even the owner leaders who are not from the engineering industry know all kinds of problems and situations of the engineering project
.
In this way, BIM Technology Combined with construction scheme, construction simulation and on-site video monitoring can greatly reduce construction quality problems, safety problems, rework and rectification
.

.
Virtual presentation, publicity and display of 3D rendering animation, giving people a sense of reality and direct visual impact
.
The built BIM model can be used as the model basis for secondary rendering development, greatly improving the accuracy and efficiency of 3D rendering effect, giving owners more intuitive publicity, and further developing extended applications such as virtual sample room for real estate companies
.

.
Rapid calculation, improve the accuracy of BIM database creation, through the establishment of 5D associated database, can accurately and quickly calculate the quantities, improve the accuracy and efficiency of construction budget
.
Because the data granularity of BIM database reaches the component level, it can quickly provide the data information needed to support the project management, and effectively improve the efficiency of construction management
.
BIM Technology can also automatically calculate the physical quantities of the project, which belongs to the function of the traditional calculation software, and there are many application cases in China
.

.
Data call and decision support
.
The data in BIM database is measurable, and a large amount of engineering related information can provide huge support for the engineering data background
.
The project basic data in BIM can be coordinated and shared among various management departments, and the engineering quantity information can be summarized, split, compared and analyzed according to the space-time dimension, component type, etc., so as to ensure the timely and accurate provision of project basic data, and provide the basis for decision-makers to make decisions on project cost group management, progress payment management, etc
.

.
Accurate planning, reduce waste
.
The fundamental reason why it is difficult to achieve enterprise fine management lies in the huge amount of engineering data, enterprises can not quickly and accurately obtain to support resource planning, which leads to the prevalence of empiricism
.
The emergence of BIM can make the relevant management lines quickly and accurately obtain the basic engineering data, provide effective support for enterprises to formulate accurate “human resources and machine” plan, greatly reduce the waste of resources, logistics and warehousing, and provide technical support for the realization of quota picking and consumption control
.

.
Multi calculation comparison, the support of effective management and control is data, the basis of project management is the management of engineering basic data, and timely and accurate acquisition of relevant engineering data is the core competitiveness of project management.
