① Track Actual Progress. On-site personnel monitor key construction areas, critical tasks, quality, safety incidents, and other elements that require special attention. They attach issues to the relevant components and locations within the BIM model using mobile devices—such as taking photos and filling out rectification forms. Management staff can promptly review the on-site status by accessing the shared model. This data can also be directly entered into the BIM platform, simplifying the analysis of all project progress-related information. Additionally, all project stakeholders can share information on the BIM platform, inputting and querying project details according to their permission levels, thereby improving communication efficiency. By tracking and providing feedback throughout the entire construction process, all parties can engage in multi-party communication and collaboration through the information-sharing platform based on the 4D model. This accelerates decision-making and allows for timely corrective actions.
② 4D Visual Progress Display. Real-time reporting of actual project progress is updated on the model or information management platform. The BIM platform uses different colors to represent the status of components—whether built, under construction, or not yet started—allowing users to monitor project completion and identify deviations from the plan at any time via milestone events. When deviations impact the overall progress target, necessary corrective measures must be taken. If adjustments to the construction plan are required, the construction team should submit the revised plan to the owner and supervisor for review and approval before implementation.
③ Dynamic Linkage Modification. Schedule deviations often require adjustments to the plan. Utilizing the dynamic linkage modification feature of the BIM management platform, updates only need to be made within the schedule management module, which then synchronizes the schedule data across all components in the 3D model. This streamlines progress modification operations. Changes can be made in any module, automatically updating related components or processes. A visual demonstration diagram helps clarify the entire modification process.
④ Generate Visual Progress Reports. The BIM management platform supports importing and associating budget and cost information, creating 5D cost management models enriched with financial data. Based on this 5D model and platform, it can automatically generate visual progress reports for each period. These reports help managers quickly assess work completion status, analyze deviations from the progress plan, and make timely adjustments. Furthermore, resource and cost investment plans can be evaluated based on the resources consumed during the period. Managers can then effectively allocate personnel and materials according to the upcoming schedule. Each progress report serves as a valuable tool for monitoring current progress and guiding decisions for the next phase, enabling real-time project evaluation and control.
Integrated Application of the 5D Platform. Achieving seamless integration of the BIM 5D platform requires two key steps: first, lossless import of all relevant data—including model details, progress updates, and cost information; second, support for data attachment and association. For instance, in the BIM 5D platform developed by Guanglian Da, a 3D model is initially created in Revit and exported in GFC format using plugins. Then, a corresponding list and quota rule project is created in GCL, where the GFC file is imported to generate the GCL model. GCL automatically calculates engineering quantities, and the GCL file is imported into GBQ (where lists and quotas are added) to produce the budget book, which is exported in igms format using GCL. Finally, the igms and GBQ files are imported into the BIM 5D platform and linked to the model, forming a model that includes cost information. Simultaneously, the schedule project file is imported into the 5D platform and associated with the model, resulting in a comprehensive model containing both schedule and cost data.
