BIM operation and maintenance analysis why enterprises should use BIM

The application of BIM in operation and maintenance can usually be understood as the combination of BIM technology and operation and maintenance management system, which can scientifically manage the space and equipment assets of buildings, prevent possible disasters and reduce operation and maintenance costs. In concrete implementation, BIM model, operation and maintenance system, mobile terminal, Internet of Things and cloud computing technology are often combined to finally realize equipment operation management, energy management, security system and tenant management.

1. 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. For example, obtain the location of building security personnel through RFID; Once a fire alarm occurs, quickly locate the position on the BIM model and check the surrounding evacuation passages and important equipment. In addition, it is also applied to the visualization of internal space facilities. Traditional construction industry information exists in two-dimensional drawings and various mechanical and electrical equipment operation manuals. When it is needed, professionals are needed to find and understand information, and then make appropriate decisions on the building. Using BIM technology, a visual three-dimensional model will be established, and all data and information can be obtained and called from the model. For example, when decorating, you can quickly obtain the relevant attributes of non-removable building components such as pipes and load-bearing walls.

Next, BIM will show you what BIM can do in the operation and maintenance stage.

2. Facilities management

Facility management mainly includes facility decoration, space planning and maintenance and operation. BIM technology 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. The original commercial real estate equipment operating independently is unified on a platform for management and control through RFID and other technologies. Through remote control, we can fully understand the running state of the equipment and provide good conditions for the owner to better manage the operation and maintenance. Equipment management plays an important role in the operation and maintenance of the subway, and it will also be widely used in some high-modernization buildings that need a lot of high technology, such as large hospitals, airports, factories and so on.

3. Take cover engineering management

Some hidden pipeline information may not be paid enough attention in architectural design, especially with the increase of building service life, the loss of these data may lay a great safety hazard for future safety work. 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.

4. Emergency management

Management based on BIM technology eliminates blind spots. Public buildings, large and high-rise buildings, etc. They are densely populated areas, and the ability to deal with emergencies is very important. Traditional emergency treatment only focuses on response and rescue, while the operation and maintenance management of BIM technology includes prevention, alarm and treatment. Once a fire accident occurs, the management system can sense the fire information through the spray sensor, automatically trigger the fire alarm in the BIM information model interface, and display the three-dimensional position of the fire area immediately. The control center can query the corresponding surrounding environment and equipment in time, providing important information for the timely evacuation of personnel and disaster treatment.

5. Energy conservation and emission reduction management

Through BIM combined with Internet of Things technology, 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 upload of building energy consumption data can be realized, which has strong expansibility. The system can also realize remote monitoring of indoor temperature and humidity, analyze indoor real-time temperature and humidity changes, and cooperate with energy-saving operation management. In the management system, all energy information can be collected in time, and the energy consumption can be automatically analyzed through the developed energy management function module, and the abnormal energy use can be warned or marked.

6. implementation 6. BIM operation and maintenance

Mode 1: Step by step. The first step is to establish a BIM model or database, and the second step is to do BIM operation and maintenance. Maybe the first step has nothing to do with the second step. First, get a BIM model with relevant data interface and reach relevant depth, accumulate basic data, and then implement the second step when it is mature.

Method 2: One step at a time. This kind of project must have clear operation and maintenance objectives and implementation methods. The limitation of this idea lies in its scope of application, and not all projects need BIM operation and maintenance.

In view of the importance of BIM technology, China has supported the research related to BIM technology since the Tenth Five-Year Plan. After years of development, it has been widely used in design and construction, but there are not many application cases in facility maintenance, so it has not been widely used. However, relevant experts agree that in the operation and maintenance stage, BIM technology is in great demand, especially in the operation and maintenance of commercial real estate, which will create great value.

With the rapid development of Internet of Things technology, the application of BIM technology in operation and maintenance management has also ushered in a new stage of development. We believe that the integration of Internet of Things technology and BIM technology into the operation and maintenance management stage of the whole life cycle of buildings will bring huge economic benefits. There is still a long way to go to truly realize BIM operation and maintenance.
