BIM plays a vital role in schedule control throughout the entire project implementation process. By using simulated construction, it guides the development of the project schedule, verifies the plan’s rationality and scientific basis, and promotes its execution through BIM technology. After project completion, BIM also supports post-project evaluation, helping to gather valuable experience and lessons for future projects.
Specifically, modeling software creates a detailed building model that incorporates physical and spatial data, along with time, cost, and quality information. Based on the project’s construction conditions, a schedule plan is developed to meet the project’s specific requirements. A time dimension link is then established, connecting the schedule data with the building model to form a 4D model of the Yitong project. This integration enables intuitive, visual, and efficient BIM-based schedule management applicable throughout the project’s entire lifecycle.
During the construction process, the building model visually represents different project statuses—whether under construction or completed—by using varying colors or levels of transparency. This approach clearly displays the actual progress, allowing for quick comparison against the original plan to identify any deviations. This method enhances management effectiveness by providing intuitive and visual progress control, minimizing information loss, and significantly improving work efficiency.
When adjustments are necessary, the schedule plan is revised and re-compared within the software. Utilizing the software’s dynamic capabilities, new models are generated to reflect these changes. The updated schedule plan is uploaded to the BIM platform, where all stakeholders can promptly access and visually assess the modifications. If issues arise with the revised plan, participants can communicate and collaborate efficiently to refine the schedule further. Once finalized, the adjusted schedule is distributed, enabling all team members to work in alignment with the updated plan, ensuring smooth project progress and timely completion with a more reasonable and scientifically sound approach.
Moreover, BIM supports post-project schedule evaluation by storing comprehensive project data and assessments. This information serves as a valuable reference for future planning and control efforts. Through BIM, construction project schedule control achieves an interactive, efficient, and intuitive simulation of project timelines—as well as the preparation, execution, adjustment, and evaluation of schedule plans.
