The eight dimension of BIM, 8D, is focused on safety during the design and construction process. This dimension aims to prevent accidents and incidents by incorporating safety features into the design of a building from the outset. 8D BIM enables designers to conduct a thorough risk assessment of each design component of the facility they are designing. By doing so, potential hazards can be identified and eliminated before construction begins, resulting in a safer working environment for construction workers.For more detailed information about one of the differnce in the D's of BIM, 9D, or 10D dimensions visit the respective blogpost.
Implementing 8D BIM into the design and construction process can help to mitigate safety risks and prevent accidents from occurring. 8D BIM enables designers to conduct a thorough risk assessment of each design component of the facility they are designing. By doing so, potential hazards can be identified and eliminated before construction begins, resulting in a safer working environment for construction workers.
“The system architecture of an 8D modelling tool for BIM-based Prevention through Design (PtD) is presented. The system includes an interface for importing BIM models in IFC file format, a PtD knowledgebase with hazard profiles of building elements, safe design and on-site hazard control suggestions, and a PtD analysis engine for hazard audits on the imported BIM model. The BIM model information is saved in an IFC file format and converted into an XML file format, which is matched with the XML file of PtD knowledgebase to perform hazard auditing. The tool produces hazard profiles with severity ratings, design revision suggestions for critical elements, and on-site hazard control suggestions for moderate and critical elements. This system architecture provides a neutral platform for hazard auditing and can help in identifying and eliminating potential hazards in the design phase, resulting in a safer working environment for construction workers
In addition to identifying potential hazards, 8D BIM also enables designers to incorporate safety features into the design of a building. For example, designers can use BIM to ensure that the facility has adequate escape routes in case of an emergency, and that safety equipment such as fire extinguishers and sprinkler systems are in the appropriate locations. By incorporating safety features into the design of a building, construction workers can work in a safer environment, reducing the risk of accidents and incidents.
8D BIM also enables construction workers to visualize and simulate the construction process before it begins. This feature is particularly useful in identifying safety risks that may not have been identified during the design phase. By simulating the construction process, workers can identify potential safety hazards, such as obstructions, and eliminate them before construction begins.
Moreover, 8D BIM also allows for the optimization of safety during the construction process. The technology can be used to track safety-related data such as safety inspections and safety-related incidents, enabling construction managers to identify trends and take corrective action where necessary.
In a detailed research in the Oil and Gas industry, the implementation of Building Information Modelling (BIM) for safety control in infrastructure construction projects was studied. The research utilized online surveys, interviews, and data analysis tools to identify barriers and safety controls for BIM implementation in maintenance projects. The study found that training and lack of roles and responsibilities are major barriers, while site layout and safety plan are key safety control aspects that can be executed using BIM.
The implementation of 8D BIM into the construction industry comes with its own set of challenges. As highlighted by the study discussed earlier, training and the lack of roles and responsibilities are major barriers to its implementation. Additionally, the implementation of site layout and safety plan is crucial for ensuring safety in a construction project, and BIM can play a vital role in executing them effectively. To overcome these challenges, a Building Execution Plan (BEP) can be developed, which outlines the roles, responsibilities, and training requirements for all stakeholders involved in the construction project. By doing so, the implementation of 8D BIM can be streamlined, and safety can be prioritized throughout the construction process.
