Construction site management encompasses various aspects, including safety, civilized construction, quality, and progress.
By leveraging BIM technology, much of this management content can be integrated into schedule management through an information-driven approach. Construction schedule management goes beyond simply recording, simulating, and adjusting the progress of the schedule. It involves multidimensional, integrated information management. The execution of a construction plan is primarily reflected in the completion of project quantities, labor and machinery participation, and material consumption.
Excluding cost factors, the concept of 5D-BIM is particularly well-suited for construction schedule management, while 4D-BIM is more appropriate for planning and revising schedules. In my opinion, 4D-BIM and 5D-BIM are concepts within BIM technology and should not be directly equated with schedule management and cost investment management in project administration.
On-site management consists of three main components: the on-site information collection terminal, the information integration display terminal, and the information processing and computing terminal. The following diagram illustrates this structure:
The on-site information collection terminal typically involves portable, high-performance mobile devices such as tablets (PADs).
The information integration display terminal can take various forms, including web interfaces and tablet displays, to receive and present data.
The information processing and computing terminal is generally a powerful server responsible for data processing.
The on-site information collection terminal plays a crucial role in BIM-based construction site management. Currently, the level of digitization in construction management is relatively low, with delays in information collection and consolidation. By utilizing Internet technology, updates on physical engineering progress can be made in real time via mobile devices and lightweight models. This data is then synchronized through networks to the processing servers for analysis or directly displayed on integration terminals.
Additionally, materials on site can be tracked using tablets. For example, when materials are neatly organized and accompanied by quantity information upon delivery, their usage can be monitored by scanning QR codes during material requisition. Remaining inventory is updated in real time to notify procurement teams when supplies need replenishing.
Moreover, equipment shifts and worker attendance can be verified by scanning QR codes on tablets. Basic worker information and completion of three-level safety training can be accessed through network synchronization. Even safety inspections such as fire checks and hot work permits can be managed via these devices.
