BIM Clash Detection: definition, types and advantages

How many and what are the different types of clashes? Everything you need to know about clash detection to revolutionize your work procedures

What is BIM clash detection?

BIM clash detection is the process that identifies potential errors in the federated BIM model, allowing them to be solved during the design phase before construction process has even begun.

In BIM modeling there's not only one model, but different models for each discipline (structural, plant, energy, etc.)

Once the various AEC professionals, each for their own specific discipline, have finished their part of the design and systems sizing process, the resulting models are merged into a single federated 3D model in which it is possible to identify any conflicts before construction. And this is where BIM clash detection comes into the scene.

The main purpose of BIM clash detection is to identify the specific points where different models can overlap. Detection of BIM interference is an essential part of the BIM workflow and ensures that there are no problems in the model that may affect project delivery or costs.

Different BIM clash detection type

There are three main BIM clash detection types:

  • hard clash: elements of separate models that occupy the same physical space, such as a duct that crosses a beam;
  • soft clash or clearance clash: elements with incompatible parameters, such as two elements that are too close to each other for assembly or maintenance;
  • workflow clash (or 4D clash): temporarily inadmissible elements, such as a very voluminous element (which does not pass through the door) which must be positioned or installed before the walls and openings are built.

The advantages of BIM clash detection

The advantages offered by BIM clash detection are numerous, among the most important:

  • Reduction of reworks on site. Detecting interferences directly on the virtual 3D model reduces the number and extent of reworks to be performed on the "physical" construction site.
  • Greater precision in all phases. Without errors or missed deadlines due to unclear projects, safer and more efficient construction projects are achieved, reducing risks and material wastages.
  • Time and money savings. Interference detections, carried out during the design phase, help reduce potential problems during the construction phase, which therefore result in significant time and money savings.

How to run clash detection of BIM models created by different designers and software vendors | usBIM.clash | ACCA software

How to run a clash detection of BIM models created by different designers and software vendors

usBIM.clash is the clash detection BIM software on federated BIM models certified by buildingSMART international®.

It doesn't matter which design software you or your design and construction team use.

With usBIM.clash:

  • open and view BIM models or objects in the IFC standard format and also in many other 3D formats (.SKP, .DWG, .3DS, etc.)
  • perform BIM clash detection tasks on projects created with Edificius®, Revit®, ArchiCAD®, Allplan®, Tekla®, VectorWorks®, AutoCAD®, SketchUp®, 3D Studio Max® and many others.

Thanks to the BIM clash detection functions, you can start from a single federated model that integrates the different design aspects (architectural, structural, plant engineering, MEP clash detection, etc.).

Hard clash or soft clash? | usBIM.clash | ACCA software

Hard clash or soft clash? You choose the most suitable type of clash detection to perform on your BIM models

From the federated model, identifying clashes is an easy task with entities such as:

  • elements of separate models that occupy the same space (hard clash), for example a pipe duct that crosses a beam;
  • elements with incompatible parameters (clearance clash), such as two elements that are too close to each other for assembly or maintenance purposes.

Just define simple ruleset parameters (type of comparison, type of collision, tolerance values) to automatically check for interferences based on the required analysis type (hard clash, clearence clash, etc.) and the degree of precision that you want to get.

IFC entity selection groups and filters help you to set up powerful clash detection rulesets available whenever you want | usBIM.clash | ACCA software

IFC entity selection groups and filters help you to set up powerful clash detection rulesets available whenever you want

usBIM.clash allows you to choose BIM models and the elements to be analysed with maximum flexibility.

You can select objects directly on the model (visually and graphically) or use advanced features such as "Selection Groups" and "Selection Filters" which allow you to specify the files and entities on which to perform conflict analysis.

Advanced features such as "Selection Groups" and "Selection Filters" allow you to specify the entities upon which to perform a geometry conflict analysis.

The chosen analysis criteria can be stored as a template and therefore used as a meta-process analysis that can be repeated each time on the updated models.

The Clash detection results are dynamically updated not only at every model change, or models that have already been analyzed, but also in case new BIM models are added.

How to see clash Detections with clear and comprehensive reports | usBIM.clash | ACCA software

How to see clash Detections with clear and comprehensive reports

usBIM.clash provides an overall and concise picture of the entire set of conflicts, their state together with an overall view of the design phase evolution.

Detected clashes and interferences (Issues) are organized in an accurate but easy to read clash report with a matrix structure in which you can easily identify:

  • objects that collide
  • the type of collision found
  • the state of the conflict (date of verification, resolution, etc.)

Thanks to the dynamic link between Issues and BIM, you can immediately identify and visualize interfering objects directly in the model.

By clicking on the collision, usBIM.clash automatically brings you back to the IFC model entities involved and highlights the collision points.

Deal with Clash detection with BCF, PDF, XLS and resolve conflicts dynamically and collaboratively

With usBIM.clash, conflicts in the design process are managed collaboratively between the different designers involved.

Enrich individual issues with notes, comments and screenshots of conflicting objects and optimize the BIM clash detection procedure.

You can export the BIM clash detection report:

  • in the standard BCF (BIM Collaboration Format) of buildingSMART international®, in line with the IFC openBIM philosophy
  • in many other standard operating formats: PDFXML, HTML, CSV, XLSX.

Using the BCF standard, the individual BIM designer can view each issue, the elements affected by the interferences and any other useful information necessary to solve the problem in their BIM application.
