The leaders of the Engineering Quality and Safety Supervision Department at the Ministry of Housing and Urban-Rural Development have provided insights regarding the definition of BIM:
BIM (Building Information Modeling) is a data management tool used throughout the design, construction, and management phases of construction projects. This technology stores all relevant project information within a parameterized 3D information model. It facilitates the communication and sharing of data across the entire lifecycle of a project—from inception to the eventual demolition of the building.
One common application of BIM is the “flipping models” approach. This method emerged when BIM was first introduced: after construction drawings are finalized, they are handed over to a BIM technology team that uses BIM software to create a detailed 3D model.
While this 3D modeling technique is widely adopted due to its reliance on BIM software, it often faces challenges. Since the BIM model is created after construction has already begun, the speed of modeling sometimes cannot keep pace with the construction progress. This lag can diminish the original value of the BIM model.
Based on practical investigations, this article identifies several reasons why BIM models often fail to reach their full potential. First, project owners frequently lack a thorough understanding of BIM’s role and capabilities. Additionally, owners or architectural firms may view BIM primarily as a way to enhance their corporate image. Consequently, BIM services are sometimes added later in the process. In some cases, architectural design companies exaggerate their BIM expertise. After securing projects, due to insufficient proficiency, they produce construction drawings using traditional methods and then create BIM models through alternative means.
Owners, focused on completing projects within specified timelines, rely on these traditional construction drawings. Moreover, most contracts do not clearly define BIM-related standards or scope of work. As a result, BIM tasks are often not effectively implemented.
