Construction teams often develop safety measures for vulnerable points and critical areas based mainly on regulatory requirements and past experience, resulting in limited precision. However, the adoption of BIM technology significantly improves this situation.
1. Construction Site Layout and On-site Material Stacking
Previously, construction sites often experienced chaotic material stacking, which lowered work efficiency and introduced safety risks for various reasons. The BIM model accurately reflects the actual site conditions. Using BIM software platforms, planners can schedule material delivery times, designate stacking locations, and optimize retrieval paths based on the construction timeline and coordination between different trades.
Special arrangements for temporary water and electricity supply locations ensure smooth progress at every stage, enhancing overall efficiency. Even when the construction sequence changes, BIM allows for real-time analysis and adjustments.
Many projects require multiple large tower cranes operating simultaneously, often placed very close together, creating potential conflict zones. To prevent collisions, two traditional methods are commonly used: measuring and calculating crane reach on AutoCAD drawings or conducting on-site crane operation tests. Both methods have limitations and can be error-prone, potentially delaying construction.
With BIM, tower cranes can be modeled parametrically, allowing users to adjust parameters and integrate site-specific models for comprehensive 3D analysis. This enables monitoring crane movements from all angles and fine-tuning to approach critical states safely without disrupting on-site operations, thus saving time and effort.
2. Fire Prevention Layout on Construction Sites
Fire prevention plans typically focus on horizontal coverage and diameter ranges, lacking dynamic real-time considerations. By integrating BIM models with construction schedules and material layouts, targeted fire safety measures can be implemented in high-risk areas.
BIM also supports simulating evacuation routes in case of fire, enabling the installation of temporary firefighting equipment along these paths to ensure safe personnel evacuation and minimize material losses.
3. Supervision of Hot Work Operations
Hot work activities such as welding, cutting, and gas torch operations require strict control on construction sites. Traditionally, issuing a “hot work permit” and assigning supervisors to oversee safety was the standard practice.
Combining BIM with safety management and scheduling allows project managers to identify hot work locations across the site before operations begin. This enables strict control over the number and validity period of hot work permits and facilitates random inspections by safety personnel at any time.
In summary, BIM technology offers powerful tools to enhance construction safety management. While opinions may vary, we hope this overview helps clarify the benefits BIM brings to site safety.
