Why are coordination services required for multidiscipline 3D models? Instead of directly explaining, why we need coordination services, I would first like to throw some light on what is coordination process and what do we mean by multidiscipline 3D models. Well, multidiscipline 3D models are nothing but the BIM models that are developed by BIM technicians or modelers for representing the design of different building systems such as architecture, structure and MEP. And coordination process is nothing but the process of clubbing together all these different 3D models.
Well, now coming back to my main point, coordination services are very crucial because of the fact that with their assistance architects and engineers are able to figure out whether the models created by them are accurate or not. The main purpose of coordination is to become aware that different models can be easily accommodated into one single master model. If in case all the different models are properly clubbed that means designs developed by different teams are perfect and do not require any further modification.
But normally what happens, while coordination process a lot of design issues in terms of coexistence of different mode elements are identified by the modelers. This requires rework or modification in the design. So now days clash detection services have become mandatory for all types of building projects. Hence as soon as all themultidiscipline 3D models are developed by BIM modelers of service providing company, they execute clash detection services on clients demand. Clash detection services are hired by Client Company so that all the clashes between the model elements can be appropriately identified. Various types of clashes are spotted or recognized during clash detection process such as hard clashes and soft clashes and it is important to resolve all these clashes for successful coordination. So clash detection is normally taken as the first step of coordination process and it is executed with the support of 3D model review software Navisworks. By successfully using the clash detective tool of Navisworks, its users can review the entire models and can find potential clashes between them. When all the coordination related design issues are rectified by modelers, they then combine all the different models into a master model. This master model provides huge clarity regarding the entire building design.
