An Analysis of the Problems of BIM-Based Drawings and Implementation During the Construction Document Phase

As construction projects become larger and more complex and the amount of information increases, the necessity of introducing BIM becomes bigger and the importance of BIM-based drawing extraction is also increasing. In particular, the construction document (CD) stage draws and documents the subjects determined from the project planning stage so that actual construction can be possible. Therefore, information management and drawings using BIM in the CD stage have a great impact on the design, construction, and maintenance stages. However, in practice, the BIM results in the CD stage do not include all the necessary information in the construction stage, and the practical use of the drawings extracted from BIM is low. To solve this problem, this study first analyzed the current status and level of BIM-based drawings in the CD stage by investigating projects that apply BIM in the Korean construction market. Next, the limitations and problems of BIM-based drawings are analyzed from a practical perspective by experts using the Delphi method. Finally, based on the results, methods to improve BIM-based drawings and work efficiency are discussed. The results of this study can be interpreted based on how the BIM is perceived in different country. However, this study analyzes the current status and problems of BIM applications from general and practical perspectives. It will contribute to further activation of BIM in the architecture, engineering, and construction (AEC) industry if BIM-based drawing standards are established based on this study and follow-up studies are conducted on the development of quality and consistency review models for BIM-based drawings.
