Traditional construction management in our country typically relies on CAD drawings combined with Excel spreadsheets. This approach often lacks clarity in information presentation and fails to establish real-time dynamic connections with the constantly evolving construction industry. As a result, slow information transmission frequently causes delays in decision-making and plan execution.
With the advent of BIM (Building Information Modeling), these issues can be effectively addressed. BIM greatly enhances construction management efficiency and marks a significant step toward refined management. Below, the author explores how BIM supports more precise construction management.
1. 3D Visualization Model Disclosure
Designers use BIM software to create 3D visual information models, moving beyond traditional 2D drawings that are often difficult to interpret. This shift improves communication between design and construction teams. Through BIM models, construction personnel can clearly understand the designer’s intent without having to interpret complex 2D plans. They can instantly observe every design detail, significantly improving their ability to read and comprehend the information conveyed by the design team.
2. Enhanced Understanding for Construction Personnel
Typically, construction teams are led by technical experts but mainly consist of workers who may not have extensive professional training. Their ability to read and understand 2D drawings can be limited, leading to misunderstandings and errors during construction. BIM’s 3D visualization allows workers to see exactly what needs to be done, how to do it, and what the finished parts will look like in an intuitive and vivid way. This greatly improves work efficiency and reduces mistakes.
3. Accurate Construction Planning
The construction team can use BIM models to simulate and demonstrate the entire construction process dynamically. This enables breaking down the required work and procedures by trade, while the model helps calculate workloads and quantities for each step. Based on this, and considering the specific conditions of the project as well as the allocation of materials, machinery, and other resources, teams can optimize scheduling and resource distribution. This approach reduces delays, work stoppages, and material waste.
4. Prefabricated Steel Structures
Large steel structures often experience significant variations during construction. Traditionally, steel components are pre-assembled in factories before being disassembled and reassembled on site. By adopting BIM technology, on-site installed steel structures can be precisely measured, and a computer model reflecting the actual conditions can be created. This enables virtual pre-assembly, improving accuracy and efficiency.
5. Standardized Component Production
BIM allows the construction team to break down building components—such as valves, doors, and windows—individually. Each component is tagged with a QR code and stored in the BIM database. This information is transmitted to the manufacturing plant via a network platform, allowing components to be produced and assembled with high precision, reducing errors and minimizing scrap risk.
6. Progress Payment Management
Using BIM, 3D models can be segmented by floors, areas, component types, and time nodes. This capability facilitates “block diagram bidding,” enabling quick and accurate monthly output audits and seamless handling of progress payments. Engineering cost managers can access and verify essential project data promptly and accurately.
In summary, BIM significantly contributes to refined construction management by addressing many limitations of traditional methods. It improves management efficiency and helps prevent project delays and cost overruns caused by poor management. Consequently, BIM is set to become a major trend for construction enterprises both domestically and internationally.
