What kind of workflow is followed for the execution of BIM coordination services? Development of immaculate buildings had always been a dream of architects, structural engineers, and MEP engineers when they did not have the availability of cutting edge tools and technology which can help them in streamlining construction work. Just a decade ago architects, engineers, contractors and fabricators who collectively work towards the successful completion of construction projects had to struggle a lot, when it comes to design development and effective management of entire construction projects. Design documentation had always been the biggest problem of architects, engineers and drafters when they did not have 2D drafting and 3D building design software products like ArchiCAD, AutoCAD and Revit etc for the development of technical drawings and 3D models. Today things have been streamlined tremendously because design and construction professionals are using AutoCAD for creating 2D drawings for architecture, structure and MEP where as Revit is utilized by them for the development of multidiscipline 3D models. BIM or Building Information Modeling services wherein 3D modeling solutions are provided to clients have really altered project execution patterns. The entire Architecture, Engineering and Construction industry depends on informative 3D models which are created by modelers in Revit architecture, Revit Structure and Revit MEP for bringing efficiency in construction. Multidiscipline Revit models can sort out the problems of architects, engineers and contractors to a great extent if it is related to design and construction. With the collective utilization of multidiscipline 3D models, modelers can identify design problems between the designs of different disciplines. For example if the elements of two different disciplines intersect, overlap or collide with each other that can be easily identified by modelers through clash detection process. The most suitable time for the execution of clash detection process is right after the accomplishment of parametric models by modelers. All the situations wherein two elements come immensely closer to each other and wherein they overlap each other are effectively identified at the time of clash detection. The next stage in Building Information Modeling process is BIM coordination wherein all the individual BIM models are combined together and a high quality 3D composite model is developed.
