BIM Technology has been widely adopted in the construction industry, delivering clear benefits. However, it also presents challenges such as model accuracy and data source reliability. Today, the BIM Architecture Training Network will discuss common issues and practical solutions for BIM technology in construction.
1. Requirements for BIM Models During the Construction Phase
The quality of the BIM model significantly impacts construction quality management, scheduling, cost control, and safety. How components are segmented and created within the BIM model determines how easily and accurately related project data can be extracted. While a finer level of detail increases the information base of components, it also raises the maintenance burden for construction personnel during project execution. Therefore, the level of detail in BIM models during construction should be balanced to effectively support construction management needs.
2. Sources of BIM Application Data During Construction
(1) From the Design Phase: The design team acts as the initial project management unit. When BIM technology is applied from the design stage, the 3D information model can be continuously used throughout the entire project lifecycle, from design through construction and operation.
If the design team lacks BIM capabilities, the construction team can create BIM models based on 2D drawing standards. For example, China is currently developing BIM drawing standards to support this approach.
(2) Modeling by Other Units: Beyond design and construction teams, other project management units can also develop localized BIM models. This helps improve work efficiency, reduce costs, and minimize decision-making errors.
3. Software Training Requirements
While mainstream BIM software promotes ease of learning and use, mastering BIM is still more challenging than traditional 2D design tools. Many construction professionals find it difficult to become proficient in BIM technology. Consequently, construction companies should establish dedicated training centers or strengthen existing training programs, recruit BIM-savvy construction management professionals, and develop tailored talent cultivation strategies. Without these efforts, they risk falling behind in future projects.
4. Limitations of Current Software Systems
Existing BIM software faces several challenges: insufficient localization, incomplete workflow coordination, lack of detailed features, and limited support from local third-party software providers. Localization efforts involve not only adding regional functionalities by the original developers but also integrating third-party software solutions to enhance practical application. Currently, most popular BIM software is designed primarily for design teams, with far fewer options tailored to construction management. Moreover, interoperability between different software platforms is limited due to the absence of standardized interfaces.
In conclusion, the establishment of a BIM model during the construction phase must primarily serve construction management objectives to maximize its effectiveness.
