Detailed mechanical shop drawings obtained from the BIM model help to eliminate clashes.  


  • Meeting Project Objectives through BIM Clash Detection Procedure

The BIM companies often divide the BIM model into separate levels and zones for coordination amongst various trades, focusing on a specific location of the building. The breakups helped to deliver smoothly, avoiding all technical glitches.

BIM clash detection procedure adopted by BIM services in USA involves accurate model creation and shop drawing production  to meet various project objectives like:

    • 3D Visualization
    • 3D MEP Coordination
    • Clash Mitigation
    • 4D Scheduling
  • BIM Quantity Take-off

Planning an Integrated BIM Clash Detection Procedure 

  • Making an effective BIM Execution Plan – BIM consulting firms provide a framework to the construction project team for implementing BIM services. The plan delineates the responsibilities of every party, as well as the scope of information to be shared with relevant business practices. The BIM Execution Plan addresses how the construction project participants would count on data from the virtual BIM models.


  • Creating a dedicated FTP Site – The establishment of a dedicated FTP site is essential for an effective BIM clash detection procedure. This is significant for uploading 3D models produced by BIM modeling companies and other subcontractors. The model becomes accessible to all project parties for coordinating architectural, structural and MEP services. BIM modeling firms integrate all 3D models into a consolidated master model, which is available to all parties for review. The master model gets updated daily and downloaded from the FTP (File Transfer Protocol) site. Every team involved in the BIM clash detection procedure gets a notification once a file gets uploaded to the FTP site. BIM modelers follow the same process while posting a consolidated 3D model.


  • Integrating BIM Model in Navisworks – BIM service companies provide an integrated composite model in a Navisworks file, including view sets of clashes and other constructability issues, revealed during the process. The team members review the saved views before the next coordination meeting.  BIM clash detection procedure also involves a 3D grid for incorporating into the Navisworks file. This provides the viewer with a quick point reference during model navigation.


  • Clash Coordination – The final stage of the BIM clash detection procedure is clash coordination. BIM modelers review the consolidated master model and save views in the coordination meeting with clients and subcontractors to discuss and resolve identified problems and adjust 3D models accordingly. The revised models get uploaded to a central FTP site and integrated into the consolidated Navisworks file. BIM engineers run a series of clashes and repeat the process during the coordination session. BIM clash detection procedure helps to detect irresolvable clashes and translate them into Request for Information (RFIs). Then a supplementary Navisworks file is saved and posted with the meeting date in a separate Navisworks Coordination folder.
