Revit Clash Detection: Improve Your Design Workflow
Revit Clash Detection is a process of identifying and eliminating clashes from the BIM models. The most common software used for clash detection is Autodesk Navisworks.
Importing Revit models in NWC format into Navisworks allows users to identify and resolve clashes between different disciplines i.e., MEP vs Architectural elements, Structural vs Architectural.
Revit Clash Detection is a powerful method for detecting clashes between different building systems, such as HVAC, Plumbing, Electrical, and Structural systems, as well as between different architectural components, such as walls, doors, and windows.
The Clash Detection tool in Navisworks compares the 3D models of different systems and components and highlights any areas where they intersect or overlap.
A comprehensive clash report is generated, helping users review the clashes and make adjustments to the design to resolve them.
The Process of Revit Clash Detection
1. Organising Revit Models
Gather Revit models from each discipline, i.e., Architectural, Structural, and MEP.
The models must be up to date and contain the latest design information. Use naming conventions for tracking the latest 3d revit model files.
2. Exporting Revit Models to Suitable Formats
To conduct clash detection in Navisworks, it is necessary to import the 3d models in formats that are readable by Navisworks.
To comply with Navisworks format, export the Revit model in NWC or NWF file format. Once you have done that, import the NWC/NWF models to Navisworks.
3. Specifying Clash Settings
To specify clash criteria, such as minimum overlap distance or particular object categories to focus on, use the Clash Detective settings. This is commonly known as the tolerance level.
4. Creating a Clash Test
Once you have specified the clash setting, you will also need to define the models to compare for the clash test. For instance, you can create a clash test between Architectural vs MEP.
5. Running the Clash Results
Once you click the “Run Test” button, Navisworks will quickly run through the potential clashes between the defined models.
Each clash will display details like involved elements, their properties and a visual representation of the model with red and green markups.
You can also generate a report in Navisworks that documents the identified clashes and their resolution status. You can also share this clash report with the respective project stakeholders to take action on the clashes.
The above 5 steps demonstrate a typical process of conducting clash detection in Navisworks.
Depending on the clash tolerance and disciplines requiring clash detection, it is imperative to define the correct clash settings and create a clash test.
Advantages of Revit Clash Detection for AEC Professionals
1. Identifying Design Errors
Design errors/changes are a major concern amongst project stakeholders. It is the ultimate goal of a design consultant or design engineer to develop an error-free design.
However, coordinating the design with different disciplines leads to clashes and errors.
Adopting Revit Clash Detection techniques allows project stakeholders to coordinate these clashes with design stakeholders and eliminate them before finalizing the design.
2. Promoting Design Accuracy
Using Navisworks promotes design accuracy right from the conceptualization stage.
Project stakeholders can coordinate their design and take necessary actions to eliminate the errors, hence promoting design accuracy.

3. Improving Collaboration
Collaboration is the key to a successful project. Architects, engineers, and contractors must communicate and work together. This becomes easier when there is just one single Revit model that serves as a coordination tool.
The model’s visual identification of clashes facilitates reasoned discussions and well-informed decision-making to address problems.
4. Controlling Cost and Time Overruns
Cost and time overruns are the biggest problems in the construction industry. These overruns not only adversely impact a company’s performance but also impact a country’s GDP.
Design changes and design errors contribute to up to 20% of cost overruns of construction projects.
All the construction companies need to control these cost and time overruns. Revit Clash Detection serves as a great tool for eliminating these clashes before a project goes on-site.
