In recent years, construction projects have become increasingly complex and demanding, making the use of 3D BIM models for communication and coordination an inevitable trend. However, on construction sites, challenges still exist when using 3D BIM, especially regarding the integration and management of 3D BIM models with traditional 2D construction drawings. Today, we will explore the integration and management of BIM models alongside 2D construction drawings.
To address the practical needs of combining 2D construction drawings with 3D BIM models during the construction phase, an integrated management system and approach have been developed. This system leverages the unique characteristics of 3D BIM, 2D barcode technology, and internet connectivity to enhance the inefficient integration between BIM models and 2D drawings.
By applying two-dimensional barcode technology in conjunction with building information modeling and a drawing description management system, the BIM model’s corresponding link is encoded into a QR code. This QR code is automatically generated and embedded into the construction drawing description when BIM software produces 2D construction drawings. Construction personnel and engineers can then scan the QR code on the 2D drawing description to instantly access and navigate the associated 3D BIM model. This integration facilitates a more intuitive 3D-assisted understanding and discussion of the drawings, greatly benefiting project teams.
The primary advantage of this automated integration between BIM models and 2D construction drawing management systems is the efficient and dynamic connection it provides. Engineers can seamlessly access both the 2D drawings and their corresponding 3D BIM models, improving workflow and clarity.
Given the substantial system resources required to handle large engineering BIM models, construction firms—both domestic and international—often segment the overall model and load only local sections as needed. Using QR codes to link these local 3D BIM models with their respective 2D construction drawings presents an effective integration method. This approach significantly enhances the efficiency of simultaneously accessing both 2D drawings and 3D models.
That concludes our discussion on the integration management of BIM models and 2D construction drawings. The author recommends gathering and analyzing relevant literature and conducting interviews with partner companies to better understand the actual needs for automated BIM and 2D drawing integration during the construction phase of building projects. A cooperating factory should serve as the pilot for implementing such a system. The goal is to propose an appropriate integration mode and establish a management system tailored to construction enterprises. Finally, it is essential to evaluate the benefits, identify challenges encountered, and develop solutions after the system’s adoption.
