Engineering data forms the foundation of construction management and supports a wide range of business information. BIM (Building Information Modeling) is a key source of this data. To utilize BIM effectively in construction management, the data must be carefully extracted, processed, and analyzed. Therefore, the timing and quality of BIM model delivery are critical factors affecting the success of BIM applications during the construction phase. In this article, we will explore the essential BIM requirements for construction management.
1. BIM Model Requirements During Construction
The quality of the BIM model significantly impacts its usefulness in later stages of the project. How components are divided and modeled within the BIM framework determines the ease and accuracy of engineering data extraction. Typically, components are subdivided based on the building’s structural breakdown and the construction organization plan. The smallest units correspond to building parts aligned with tasks outlined in the Work Breakdown Structure (WBS). This approach allows the generation of various data formats tailored to specific needs, ensuring BIM data precisely supports construction management requirements.
2. Primary BIM Data Sources for Construction Companies
A common practice is for construction companies to receive BIM models from external sources. The emerging trend favors outsourcing model creation to third parties—such as design teams or project owners—who then supply BIM models to construction firms. Construction companies can then refine or reorganize components or groups as necessary. For example, when applying the skip warehouse method for floor construction, a floor may be divided into several sections according to the construction plan, providing accurate data for effective management. This refinement process is best handled by the construction company itself to ensure alignment with BIM construction management needs.
Alternatively, some construction companies opt to develop their own BIM models by having their personnel build directly from design drawings. This method deepens the construction team’s understanding of the project’s finer details and guarantees that the BIM model aligns precisely with construction management requirements.
3. Scheduling BIM Model Development
Based on practical experience, BIM modeling should be completed by the end of excavation. The model must be substantially finalized before foundation work begins to prevent disruptions to construction management workflows. For projects around 150,000 square meters, the BIM modeling process typically takes about 40 days.
4. Information Granularity in BIM
Maintaining the BIM model’s information is a vital responsibility. Beyond promptly updating the model to reflect design changes, all related data must remain accurate and complete. Higher granularity means including detailed entries—such as specifications and model types—for each component. However, too much detail can overwhelm construction personnel with maintenance tasks during project execution. Therefore, the level of information should strike a balance: detailed enough to support construction management effectively without adding unnecessary complexity.
In conclusion, we have outlined the key BIM requirements essential for construction management. Presented from an expert perspective, this overview aims to inspire and assist professionals in the field. We encourage readers to share their insights and join the conversation.
