Using BIM technology to simulate the construction site environment—including the layout, as well as the placement and handling of equipment, tools, and materials—can significantly enhance construction efficiency. By applying BIM, we can visualize surrounding facilities, equipment installations, and other site-related issues within a simulated environment. This approach helps optimize factors influencing construction productivity and prevents potential accidents. Additionally, integrating the model with the Internet allows real-time monitoring of pedestrian and vehicle flow on the site, ensuring smooth transportation, improved safety, and higher efficiency.
1. Data Preparation Stage
This includes simulating the construction process, gathering site road data, material information, equipment models, security locations, and safety settings. It also involves analyzing traffic flow, the time schedule, and environmental conditions around the construction site.
2. Basic Operational Procedures
1. Collect and organize relevant data from reliable sources.
2. Using the actual site conditions, build a site model with software, input the location of the onsite lifting tower, and the construction red line position, then verify whether the lifting tower could cause collisions during construction.
3. Within the simulated environment, plan the stacking positions for materials, machinery placement—especially substations—fire extinguisher locations, and other critical construction facilities to ensure safety and efficiency.
4. Integrate the model with IoT data by adding access control and monitoring systems to track the flow of people and vehicles within the site in real time.
5. Design evacuation routes and temporary parking areas for vehicles within the model.
6. Generate regulatory and compliance reports promptly throughout the construction process.
3. Applying BIM Technology in Temporary Construction Planning
1. Planning On-Site Temporary Construction
Construction companies should develop standardized model modules for elements such as security posts, office buildings, accommodation, canteens, and activity areas. Based on project size and workforce, these modules can form the project department’s layout. BIM technology plays a critical role in guiding actual project execution, as illustrated in Figure 3-8. Finance and technical teams can estimate project costs in advance by referencing the engineering model. Moreover, BIM-designed enterprise images can be utilized for promotional purposes.
2. Temporary Access Roads
Once the construction scope is finalized and road paving is mostly complete, materials must be transported according to construction needs. Temporary roads should be established within the site, with models and actual traffic data analyzed via software to assess maximum traffic saturation. To ease congestion—especially in areas with frequent heavy vehicle traffic such as concrete trucks—staggered platforms and road condition signs should be installed at intersections. Proper traffic management is essential to avoid site bottlenecks. In Figure 3, the black area represents a temporary roadbed widened from the original to improve vehicle accessibility.
3. Mechanical Equipment Placement Planning
After constructing the main site model, equipment and machinery placement must be planned based on this model and existing road layouts. Tower cranes and overhead cranes are positioned according to the completed site layout. Traditionally, crane placement requires analyzing multiple construction drawings. However, as shown in Figure 4, BIM technology enables three-dimensional simulation of tower crane and overhead crane setups, offering a more intuitive and accurate approach. During project execution, BIM also facilitates adjusting the number of tower cranes to improve construction efficiency without compromising safety.
In summary, BIM technology offers invaluable support for temporary construction planning on bridge engineering sites. We hope this article provides helpful insights to everyone interested in leveraging BIM for enhanced construction management.
