BIM technology offers comprehensive foundational data for construction project management, making information more systematic and intelligent. This addresses the common issue of insufficient engineering data in cost management and supports refined project control. The engineering database created through BIM provides a scientific basis for all cost-related decisions throughout the construction process. Project budgeters, procurement officers, technical staff, and other stakeholders can record, update, and share cost information anytime and anywhere via information terminals and BIM data platforms. This ensures data remains real-time, accurate, and easily accessible for verification and retrieval.
BIM technology can simulate construction activities ahead of schedule, allowing the system’s data and models to be updated continuously as the project progresses. By integrating BIM models with scheduling and cost data on a 5D platform, quantities can be analyzed from multiple dimensions—such as tasks, timeframes, and components. This enables cost calculations for any construction phase or building area, facilitating precise “block diagram bidding.”
The visualization capabilities of BIM models and automatic recognition of physical quantities allow cost summaries to directly correspond to visible model elements. This facilitates statistical analysis based on the actual site conditions, creating a unified standard for control. The model’s information integration enhances collaboration in construction management and improves the reusability of engineering data, increasing the efficiency of information flow. When extracting past data, there is no longer a need for repeated manual organization or selection of relevant information, moving beyond rough estimations based on experience.
BIM’s dynamic simulation helps evaluate the feasibility of construction plans by demonstrating complex sequences and methods in advance. It realistically replicates on-site conditions, enabling project teams to identify issues early, optimize plans, and reduce technical problems caused by communication gaps. Virtual construction with BIM refines resource allocation, minimizing waste while providing detailed visualization throughout the entire process, which supports precise project management.
The adaptability of BIM information allows real-time input of actual site conditions into the model. This creates opportunities for timely analysis and detection of deviations—an essential requirement for dynamic project management.
BIM’s 3D functionality and integrated data ensure that system data corresponds directly to model elements, forming a cohesive whole rather than fragmented data sets. When deviations occur, the exact on-site events during the analysis period can be visually replayed without relying solely on static documents like logs or drawings. This greatly facilitates dynamic cause tracking and the evaluation of successes and challenges.
The multi-factor collaboration enabled by the BIM 5D platform allows comprehensive control over both cost and schedule. Precise material quantity increases can be tracked using the model databases and the 5D platform. This supports detailed cost and schedule studies, breaking down milestones by time and task. It provides technical backing for deep deviation analysis using the WBS (Work Breakdown Structure) method in dynamic control. The integration of BIM with computer technology has revolutionized cost control information sharing, making construction processes more transparent and boosting market standardization.
