What is Clash Detection & Coordination? Clash Detection services is the initial step in BIM coordination process. BIM Clash coordination is executed to coordinate the spaces and tolerances needed for placing the various services in a building. While designing, there are several models like architectural, structural, civil, and MEP services, and their interconnections sometimes result in conflicts in terms of space allocation. Through BIM clash detection service and MEP coordination, conflicts can be resolved by effectively identifying the problem areas, inspecting and reporting about the services to the respective contractors and finally coming to a solution. Early clash detection removes the risk of error in the construction site, thus saving money and increasing productivity.
