In traditional schedule management, coordinating multiple construction units often proves challenging due to varying management capabilities and external factors. This lack of synchronization across units leads to fragmented schedule management, which frequently causes delays in construction plans. Additionally, the limited foresight of general contractors and construction teams regarding schedule deviations results in increased costs related to engineering expenses.
Leveraging BIM technology for highway construction schedule management transforms traditional methods by integrating 3D models with time data. This approach breaks down the overall construction schedule into specific milestones based on sub-tasks and processes, embedding timing information to create a 4D-BIM scheduling system. This system enhances communication, data exchange, and collaboration among all project participants, enabling real-time dynamic management of on-site progress.
The 4D-BIM progress management system can simulate the construction sequence according to the schedule, identify potential influencing factors, and optimize planning accordingly. It also calculates resource requirements—including personnel, machinery, equipment, and funding—based on the construction plan. When the schedule changes, the system automatically updates resource allocations.
Through this system, construction managers and teams can easily access detailed information about each subproject’s timeline, quantities, construction methods, and responsible units. If there is a discrepancy between actual on-site progress and planned expectations, the system promptly updates progress data, adjusts resource distribution, and visually presents these changes using 4D graphical representations.
