How is BIM technology applied in construction project management?

With the continuous development of society, the scale of modern construction projects continues to expand. There are some drawbacks in traditional construction management, which are mainly reflected in improper construction quality control, chaotic management methods, and slow project development. . In response to the above situation, construction units should focus on improving quality, reducing project costs during the construction process, and using BIM information technology to improve construction project management methods. The article starts from the related concepts of BIM and analyzes its application in construction project management.

In recent years, people's quality requirements for construction projects have continued to increase, making construction projects more difficult. Traditional technical construction methods are no longer suitable for the application of modern management, and it is difficult to meet the development needs of the construction industry. Therefore, construction units must use information technology as the basis to carry out in-depth reforms in construction management, quality control, progress control, cost control and other aspects to promote the development of the construction industry.

1 Overview of BIM related theories

1.1 Concept of BIM

Since the emergence of BIM technology, people have limited its concept. From a general perspective, it refers to targeting construction projects and creating an operation and maintenance process that satisfies owners by controlling costs and improving quality. From the contractor's perspective, it is a method of monitoring the construction process by tracking the construction site according to the standard plan under the condition of simulating the construction site. From a design perspective, BIM technology incorporates an automated supervision system that can draw specific design drawings based on known terrain. Judging from the development trend and process of this technology, it is not static. The system will be upgraded according to the specific requirements and conditions of construction to produce the most accurate measurement data. The biggest advantage of BIM technology is that it penetrates into all aspects of construction projects, from construction progress to quality supervision and project management. This not only achieves access to information data, but also expands the technical operation and maintenance space.

1.2 The core of BIM technology

As an advanced construction engineering management technology, its core control points lie in the following aspects: ① It can establish a three-dimensional analysis platform for data . Under process control, abstract drawings become more concrete, and managers can control them in this way; ② Each data does not exist independently, it has a certain correlation, and it can share information resources at the same time Deepen internal systems, integrate simulation platforms, and achieve data interactivity. The sharing of different professional information enhances the participation of construction projects, and managers can realize remote monitoring of construction sites [2]; ③ The rate of project intervention is increased. Construction project managers can intervene in quality management content decisions anytime and anywhere, and make the most positive response based on project benefits.

2Application of BIM technology in construction project management

2.1Application of BIM technology in construction quality

The behavior of materials and construction personnel is important to ensure quality condition. In terms of the behavior of construction workers, BIM technology reflects the overall environment of the building in the form of three-dimensional images and guides construction. This technology will establish multiple solutions based on specific situations, compare the results, and analyze the shortcomings and advantages of different solutions. Managers use their own judgment to choose the most appropriate method. The integration of BIM technology is also reflected in on-site operations. The virtual platform will establish different construction sequences and achieve effective control through testing the efficiency of on-site personnel. In addition, it has the function of visual simulation guidance, and can use the combination of GPS positioning technology and mobile communication technology to control the construction scope [3].

2.2 Application of BIM technology in construction costs

The application of BIM technology in construction management is mainly reflected in construction cost control. The construction phase of a construction project can also be called the formation process of the engineering entity. It involves a wide range of aspects, including human resource management, construction cycle control, material and equipment management, etc. If you want to improve the quality of construction, you must start from the above aspects to achieve reasonable preparation of plan progress and improvement of quality. From the establishment of the three-dimensional model using BIM technology, the data will be reflected in the form of images, and the construction combination plan and progress of each stage will be more intuitively displayed.

Information technology will plan the overall environment and list it into a detailed usage list of funds and personnel. Managers can compare the standard parameters with the actual scale, and build materials and hire personnel according to the limited quota. This avoids the problem of excessive construction costs caused by delayed communication with suppliers. The technology also enables testing in live environments. Including address conditions, water supply and power supply status, etc. If there are changes in natural factors, the system will automatically issue early warnings and control the construction progress on site. This not only reflects the establishment of architectural models, but also saves project costs. At the same time, cost management is also reflected in the reduction of project quantities.

3 Application of BIM technology in construction progress

BIM technology can be applied to the three stages before construction, during construction and after construction, throughout the entire construction process, so as to improve the construction progress. Consistent with the construction plan and schedule requirements.

3.1 Application of BIM technology before construction of construction projects

BIM technology can be used in the management of construction projects before construction. Under BIM technology, drawings can be displayed in the form of three-dimensional images, and the process, progress and various links of the project can also be displayed intuitively in front of managers. Managers can extract the above information at any time, compare it with the actual situation of the project, and judge whether the drawings, processes and progress are consistent with the project requirements, thereby ensuring the rationality and scientific improvement of the construction.

3.2 Application of BIM technology in construction projects

BIM technology can be applied to the construction process of construction projects. The construction links of construction projects are complex. Managers can use the drawings designed under BIM technology, planned construction processes, and formulated construction plans as references to guide the smooth development of each link of the project. The application of BIM technology can enable managers to start from the overall situation and realize For comprehensive management of construction, BIM technology has the function of visual simulation guidance. Managers can conduct on-site supervision through the Internet, control the construction operation process, and improve its coordination, which has positive significance for improving management efficiency.

3.3 Application of BIM technology after construction of construction projects

After construction, BIM technology can be used to inspect the construction quality, thereby comprehensively improving the construction level of construction projects.

4 Conclusion

The article starts from the relevant overview of BIM technology and analyzes its application in construction project management. It can be concluded that: as an advanced three-dimensional information technology method, it can penetrate into all aspects of construction quality, progress, inspection, cost, etc.; it can provide a reference basis for on-site management, realize automated modification and management; and provide guidance for the construction site , improve work efficiency on the basis of project quality assurance, and create favorable conditions for project cost savings and changes in management methods.
