BIM technology enables intuitive on-site simulation through 3D information models, based on textual specifications, standards, and construction requirements. It provides operators with clear visual interfaces that clarify workflows and building structures, offering reliable references for on-site operations. This visualization also helps identify construction defects, detect hazards and safety risks, and deliver feedback to all involved parties, thereby enhancing on-site safety management.
Precise Opening Reservations
Opening reservations in precast concrete components or cast-in-place concrete walls and slabs are often challenging due to inaccurate designs. Typically, pipelines are installed through rear openings, which can damage stressed steel bars, compromise structural integrity, and pose significant safety risks. Using a detailed 3D dynamic building information model created in REVIT, component data is easily accessible with vivid, intuitive visualizations. This allows for precise, visualized reservation of equipment pipeline openings in walls and floors, eliminating the need for secondary construction, saving labor, and preserving the integrity and appearance of these components. By avoiding structural damage, this method maintains the original safety performance of walls and slabs, ensuring load-bearing capacity and preventing potential collapses.
Hazard Identification and Safety Protection
Construction sites contain numerous hazardous zones that are difficult for safety personnel to monitor in real time, often leading to protection gaps. By integrating BIM with RFID (Radio Frequency Identification) technology, the site can be divided into danger zones based on proximity to edges and openings. Areas within 0.5 meters are classified as Level 1 hazards and marked in red. Zones between 0.5 and 1 meter are Level 2 hazards, marked in yellow, while areas beyond 1 meter are considered safe and marked green. RFID antennas cover the site, and workers wear helmets equipped with RFID tags. Identification devices are installed at key points near edges and openings. Data collected from RFID readers is processed by a central BIM information system for real-time visual monitoring. If protective measures are missing, defective, or not aligned with the 3D model, the system triggers hazard warnings and provides immediate feedback. The visualization module also tracks workers’ positions in real time within the 3D model, issuing urgent audio warnings when workers enter hazardous zones. These alerts are sent promptly to safety management personnel, enabling timely protective actions and adding an extra layer of defense. By pinpointing hazards and controlling unsafe behavior, this system helps prevent high-altitude falls and other accidents.
Collision Detection
Given the complexity of engineering designs, errors and conflicts are inevitable. BIMNAVISWorks technology is employed to perform collision detection on 3D models of buildings, structures, mechanical systems, and pipelines. Detected collisions are cataloged and compiled into a comprehensive report, which includes construction details, location, images, and manufacturer specifications. This report facilitates targeted design revisions at collision points or the adoption of new methods and technologies to avoid conflicts. For collisions that cannot be avoided, experts conduct safety analyses to develop appropriate safety plans, optimize construction sequences, and prepare protective measures in advance. This process provides accurate technical support for construction and significantly reduces safety risks on site.
