BIM technology-based progress control effectively overcomes the limitations of traditional methods, such as flat result displays, delayed error detection, and cumbersome data updates. By integrating BIM, schedules can be simulated in advance, providing managers with clear visualizations and intuitive data analysis. This allows for quick adjustments and contingency planning in response to unexpected changes, ensuring smooth project progress. Construction schedule simulations also enable managers to evaluate the suitability of different plans, allowing them to compare alternatives and select the most optimal approach. Furthermore, managers can monitor expected outcomes and promptly correct any deviations. The adoption of BIM in schedule management represents a significant advancement in the construction industry, poised to revolutionize project control.
BIM-based progress control enables real-time data updates and tracking, supported by an information platform that offers diverse management options. By combining a 3D model with a timeline, a 4D BIM model is created. This model allows extraction of comprehensive building information, while component parameterization facilitates collaboration among various professionals and designers. BIM analyzes schedule control content from two main perspectives:
(1) Establishing a site-adjacent platform with the project team to gather firsthand information. This platform’s primary function is to collect, transmit, and manage project updates promptly, while also receiving feedback from other systems to implement necessary changes.
(2) Integrating collected information with the BIM model to visually represent all data in three dimensions, simulate construction progress, identify management issues in real time, and enable timely corrections.
The foundation of effective progress tracking and research is the establishment of an information platform. This platform is central to BIM technology, distinguishing it from other methods through its use of information throughout the project lifecycle. All stakeholders and departments can update and correct project data as needed. In the early project stages, participants gather relevant data and input it into the BIM model to enhance its accuracy. Data collection can be manual or automated: manual methods involve technical personnel using mobile devices such as phones and tablets to capture project changes, while automated methods rely on pre-installed monitoring equipment that performs continuous data collection without human intervention. Modern tools like 3D laser scanners exemplify this automated monitoring technology.
