BIM technology, its embryonic form can be traced back to 1970s. After 2 1 century, with the rapid development of computer software and hardware level and in-depth understanding of building life cycle, BIM technology is gradually recognized by engineers. Since 2002, the wave of BIM reform has swept the world, and BIM technology has begun to develop.
With the development of domestic architectural design field, BIM has been initially applied to the construction engineering industry, and shows its great commercial value! With the vigorous promotion of BIM technology in China, many enterprises have a strong sense of BIM, and at the same time, a number of benchmark projects for BIM application have emerged. Such as China Zun and Wangjing SOHO.
But what is the market development of BIM at this stage? What kind of practical application is there? This paper mainly analyzes BIM technology from three aspects: the main content of BIM application in construction enterprises, BIM application in operation and maintenance stage and BIM talent demand module.
1. Main contents of BIM application in current construction enterprises
Collision check to reduce rework
Using the three-dimensional technology of BIM to check the collision in the early stage can intuitively solve the conflict of spatial relationship, optimize the engineering design, reduce the possible mistakes and rework in the construction stage, and optimize the pipeline layout scheme. The constructors can make use of the optimized collision scheme for construction disclosure and construction simulation, so as to improve the construction quality and the ability to communicate with the owners.
Simulated construction, effective coordination
Three-dimensional visualization function plus time dimension can be used to simulate the construction progress. Compare the construction plan with the actual progress intuitively and quickly at any time and place, and cooperate effectively at the same time, so that the project participants know all kinds of problems and situations of the project like the back of their hands. Thereby reducing building quality problems and safety problems, and reducing rework and rectification.
Three-dimensional rendering, publicity and display
Three-dimensional rendering animation can give customers a sense of substitution through virtual reality, give people a realistic and direct visual impact, and cooperate with bidding demonstration and construction stage to adjust the implementation plan.
BIM model can be used as the model basis of secondary rendering development, which greatly improves the accuracy and efficiency of 3D rendering effect, gives owners more intuitive publicity and introduction, and can improve the probability of winning the bid in the bidding stage.
Knowledge management, saving information
In the simulation process, we can acquire knowledge and skills that are not easy to accumulate in the construction process, and save all the information in the construction process, which can not only save complete information, but also quickly find the source of the problem in the operation and maintenance process.
2. Application of 2.BIM in the current operation and maintenance stage
space management
Space management is mainly used for the space positioning of lighting, fire fighting and other systems and equipment. Obtain the spatial position information of each system and equipment, and change the original digital or text representation into three-dimensional graphic position, which is intuitive and convenient to find.
facilities management
It mainly includes the decoration, space planning, maintenance and operation of facilities. The characteristic of BIM technology is that it can provide coordinated and computable information about construction projects, so this information is worth sharing and reusing, and owners and operators can reduce the cost loss caused by lack of interoperability. In addition, it can also remotely control important equipment.
Concealed engineering management
With the increase of the service life of buildings and the frequent turnover of people, these security risks have become increasingly prominent, sometimes directly leading to tragedies. The operation and maintenance based on BIM technology can manage complex underground pipe networks, such as sewage pipes, drainage pipes, network cables, wires and related pipe wells, and can directly obtain the relative position relationship on the map.
During reconstruction or secondary decoration, the existing pipe network position can be avoided, which is convenient for pipe network maintenance, equipment replacement and positioning. Internal related personnel can enjoy these electronic information and adjust it at any time to ensure the integrity and accuracy of the information.
emergency management
Management based on BIM technology will not have any blind spots. Through BIM system, we can quickly locate the location of facilities and equipment, and avoid looking for information in the vast number of drawings. If it is not handled in time, it will lead to a catastrophic accident.
Energy saving and emission reduction management
Through the application of BIM combined with Internet of Things technology, the daily energy management monitoring becomes more convenient. By installing electricity meters, water meters and gas meters with sensing functions, basic functions such as real-time collection, transmission, preliminary analysis and fixed-point uploading of building energy consumption data can be realized, which has strong expansibility.
3.BIM-related talent demand
Now that BIM technology is in the stage of rapid development, enterprises will examine talents from all aspects. Knowledge and skills, software tools used, working methods and processes, work quality and delivery results are all key factors that enterprises need to consider.
Therefore, BIM, as a tool and platform at the beginning, will inevitably become a hard indicator for selecting and allocating talents in the future. And this choice is not limited to technicians, but covers all employees. So in this sense, BIM is the development trend of the future engineering industry. This is not only a necessary skill for a career, but also a necessary tool to improve your competitiveness! With the gradual increase of professionals, BIM will surely lead a new revolution in the construction industry.
