Clash detection

Estimated reading: 4 minutes 370 views

BEXEL Manager’s Clash Detection module can perform geometric conflict analysis against any given number of groups of elements. Clash avoidance is an essential part of the design and construction process with the aim to allow execution of the project without problems in quality, delays or additional costs. Mechanical, Electrical & Plumbing systems usually consist of many elements, creating a highly complex linear system, which must be carefully placed within the building structure. Typically, most conflicts occur within or among different MEP systems or between architectural and structural components and MEP elements.

The Clash Detection palette is by default located at the bottom of the screen and additionally can be moved to the desired place using the drag-and-drop option. The Clash job represents a clash analysis between two clashing groups. When creating a New Job, the system detects clashes, as per the defined clash type and tolerance, between the individual clash detection groups defined in the Clash Detection window. The results are presented as a specified list of all detected clashes between the elements of the groups selected for a particular job.

There are several types of checks for different stakeholders and stages of the project, for example:

  1. How to import the clash detection matrix and rules to prepare the model for the appropriate clash detection check?
  2. Are there any duplicates in the model because of using different authoring software or sources?
  3. How to simplify the clash detection list with a large number of clashes?
  4. How to locate a clash on the floor plan and detect collision density on the current floor?
  5. How many main conflicts are in the clash detection job?
  6. Are there any problems that can stop or delay on-site works in the next period?

After model checking, reports and information can be shared between stakeholders on the project in different ways:

  1. Exporting Clash analysis report in HTML and pdf file format ➡️
  2. Reporting issues using Power BI + Bexel Viewer ➡️
  3. Reporting issues using Power BI ➡️
  4. Sharing issues with other stakeholders using BCF Manager ➡️

The Clash Detection palette is by default located at the bottom of the screen. You can drag this palette and move it to the desired place.

The Clash job represents a clash analysis between two clashing groups.

Clash Matrix and Clash detection rules are the main inputs for Clash detection jobs. Clash Matrix establishes the hierarchy and main rules between different construction disciplines, defining the type of clash and setting exact distances for clashes (clearance, tolerance). It can be in the table form to clearly set and see the intersection of different disciplines and their categories.
