BIM data possesses the following key characteristics:
Objectivity. BIM serves as a comprehensive information model that connects data, processes, and capital throughout the various stages of a building project’s lifecycle. It offers a complete representation of power engineering objects and accurately reflects the actual productivity levels in this field. By integrating BIM models with real project progress, dynamic comparisons between estimated and actual costs become possible. This allows for timely monitoring of quality and safety, enabling adjustments in planning and execution to enhance overall governance in terms of cost, quality, and scheduling.
Integration. Data within the BIM model evolves alongside project objectives, relying on the collaboration and cooperation of all stakeholders. This synchronization continues until the project is completed and operational. BIM efficiently organizes information, establishes organic relationships, and forms a 4D relational database. This approach addresses issues commonly seen in traditional governance models, such as fragmented oversight processes and isolated information silos. See Figure 1: Comparison between Cost Data Platform and Traditional Governance Model.
Accuracy. BIM data achieves component-level precision, providing rapid access to the information necessary for effective project governance. It proactively generates detailed data and equipment lists, supporting tasks such as quantity calculation, cost estimation, budgeting, and final accounting in power engineering projects. Additionally, BIM enables on-site managers to directly compare the original support models with actual on-site conditions, making assessments more scientific and reliable.
Timeliness. BIM models deliver timely and accurate cost information for power engineering projects, offering a solid foundation for decision-making in similar future projects. During phases of project scope divergence, involved parties can insert, extract, update, and share data within the BIM system, which features powerful querying, analysis, and statistical capabilities. This helps mitigate numerous site issues by allowing cost management personnel to compile these data into cost indicators tailored to divergence management needs.
Planned Resolution. Effective cost management requires realistic power engineering data as the foundation for all unexpected project resolutions. The BIM data model enables clear visibility into capital applications, facilitating short-term control over financial risks and profit targets. Through its relational database, it accurately and quickly calculates project quantities, improving budgeting precision and efficiency. At any point in time, basic project data can be extracted and compared against contracts, planned versus actual consumption, unit prices, and sub-item totals. This comparison helps identify profitability and detect any consumption exceeding standards. Moreover, by combining process modeling with real project progress, BIM allows dynamic cost comparisons, timely monitoring of quality and safety, and adaptive planning adjustments—ultimately raising the overall governance quality related to cost, quality, and scheduling.
