Currently, China’s construction industry remains a traditional, labor-intensive sector with relatively outdated production methods. This extensive approach no longer aligns with the national development strategy focused on industrialization and informatization. The introduction of Building Information Modeling (BIM) technology has gradually revealed its potential as a powerful tool for digitizing construction projects. BIM enables the exchange and transmission of digital project information throughout the entire construction lifecycle, replacing the traditional point-to-point communication reliant on paper documents. Consequently, BIM technology is driving fundamental changes in the construction industry’s technology, management, and systems.
Digitized project information also promotes a more efficient EPC (Engineering, Procurement, and Construction) general contracting management model that integrates design, production, and construction. This helps the construction industry overcome its previous limitations. The following sections compare and analyze project information management under BIM technology versus traditional construction methods, highlighting the application value of BIM in construction projects.
1. Traditional Construction Material Handover vs. BIM Digital Management
In traditional construction, material handovers mostly rely on paper documents and occur through point-to-point or face-to-face communication. This process is highly susceptible to human error, leading to potential delays or even loss of project information across different stages and stakeholders involved in the construction lifecycle.
BIM technology, on the other hand, creates a digital model of the construction project where all relevant information—such as design details of prefabricated components, material properties, costs, and personnel data—can be freely entered and managed. This virtual model supports building performance analyses during the design phase, including sunlight exposure, wind environment, and energy consumption assessments. Furthermore, BIM enables the direct generation of project drawings, ensuring accuracy and efficiency.
Another key advantage of BIM is its adjustability: when modifications occur during project implementation, the software automatically updates related elements in the model, maintaining consistency and ensuring the reliability of project information throughout construction.
2. Unified Standards and Collaborative Software in BIM vs. Fragmented Traditional Practices
Currently, environmental standards for generating project information during construction vary widely. Designers work according to different specifications and drawings, while other specialists extract necessary information using their own professional software. Since various disciplines use different software platforms, project information is repeatedly extracted and re-entered. This process often results in poor data compatibility, loss of information, delays, and errors.
BIM technology addresses these issues by integrating software tools used across different disciplines within the construction process. It standardizes data input and output formats, supporting seamless collaboration among project participants. This unified approach improves the efficiency of project information management, ensuring consistency and accuracy throughout the project’s lifecycle.
3. Enhanced Integration and Information Management through BIM
With the rise of construction industrialization and information technology strategies, there is an increasing emphasis on integrating and managing project information efficiently. Under traditional methods, project data at various stages tends to be scattered, making integration complex and labor-intensive.
BIM serves as an effective tool for integrating and managing both structured and unstructured information scattered across different locations and management systems. It provides timely access to integrated information for all stakeholders and offers a collaborative platform that facilitates smooth communication and teamwork throughout the construction project.
