Significance of 3D BIM coordination services in construction BIM coordination services are carried out largely in Revit which is highly indispensable building design software. Design is developed separately for different building trades in the preconstruction phase and hence it becomes truly significant to coordinate multidiscipline models for realizing the validity and authenticity of the models. As more and more sophisticated buildings are constructed now days, it’s sort of important for design and construction professionals to perform a quality control check on drawings as well as on models before they are coordinated. Traditionally, when effective building design software wasn’t available to design and construction professionals, whether it’s the identifications of clashes or the coordination of different trades everything used to be carried out manually which involved large chances of human errors. But Building Information Modeling which is considered as an effective visualization tool helps architects and engineers in visualizing the potential conflicts that exist between the design elements of different building trades. This is because multidiscipline models are created by architects and engineers in 3D by using BIM tools and these models can be observed by its users from every feasible angle. When BIM coordination services are hired by clients they achieve effective outcomes by them. In the beginning clash detection is performed by the competent staff of the company wherein in innumerable clashes between design elements are identified. Identification of clashes is followed by providing effective solutions for them which is normally done by implementing changes in the location of the model elements. When all the destructive and dangerous clashes are fully rectified by design and construction professionals then comes the point when their coordination is required. Now the staff of service providing company needs to switch from Navisworks to Revit for performing BIM coordination. All the models which have recently been checked for the potential clashes should now be coordinated with each other in Revit. This time around no hardships are faced by AEC professionals in terms of conflicts between model elements when it comes to their coexistence. This is way a composite BIM model is created by design and construction professionals which indicates flawless construction ahead.
