BIM (Building Information Modeling) Clash Coordination is a crucial process in the construction industry that utilizes BIM technology to detect and resolve clashes or conflicts among different building systems or elements before the construction phase begins. Clash coordination is a proactive approach that helps prevent costly and time-consuming clashes that may arise during the construction process.In a construction project, various disciplines, such as architecture, structural engineering, mechanical, electrical, plumbing, and others, create their respective models using BIM software. Each model contains valuable information about the design and layout of the components relevant to that discipline.
However, conflicts may arise when these different models are combined or integrated into an overall building model. Clash coordination involves checking for interferences, overlaps, or collisions among the various building elements. Some common clashes include ductwork conflicting with structural beams, pipes intersecting with walls, or electrical conduits interfering with other services.
The clash coordination process typically follows these steps:
Model Creation: Each discipline creates their BIM model, incorporating all the relevant information about their systems.
Model Integration: The individual models are combined into an aggregated BIM model representing the entire building or construction project.
Clash Detection: Clash detection software or BIM tools are used to identify and highlight clashes among the different building elements.
Clash Resolution: Once clashes are identified, the project team collaborates to resolve the conflicts. This may involve adjusting the design of one or more building systems to avoid clashes or re-routing services to accommodate each other.
Model Update: After resolving the clashes, the individual models are updated with the changes made during the coordination process.
Iterative Process: Clash coordination is often an iterative process, where the models are continually reviewed and updated to ensure that any new design changes do not introduce additional clashes.
The benefits of BIM clash coordination are numerous:
Cost and Time Savings: Detecting and resolving clashes during the design phase prevents rework and delays during construction, saving time and money.
Improved Collaboration: Clash coordination encourages interdisciplinary collaboration, enhancing communication and understanding among different project stakeholders.
Enhanced Visualization: BIM technology allows stakeholders to visualize the clashes in 3D, making it easier to understand and resolve conflicts.
Reduced Construction Errors: By addressing clashes before construction, the likelihood of on-site errors and conflicts is reduced.
