Identifying and assessing potential clashes

Clash detection is one of the best functioning tools developed for 3D coordination. Modern coordination is too large and complicated to manually check for clashes between MEP services or with the structure. Clash detection software allows for automatic checking for these issues. Blue Thorn have been using this technology since 2002, even though it has only recently become much more universally used.

Blue Thorn will always carry out full clash detection on our coordination solutions, as well as general project clash detection when working for you in a BIM Management role.

Clash detection is not a binary issue

Blue Thorn understand that proper clash detection is not just a black and white issue of whether elements clash or not. Clashes need to be assessed properly to understand the likelihood of them being an issue on site and the consequences of what the clash, or the resolution of a clash might mean. This can be seen in the following two examples:

  1. Two pipes crossing each other may have a slight clash on their insulation. Depending on the insulation type, this may be able to be compressed on-site and the pipes installed as originally modelled instead of presenting a solution where one is set around the other. This may possibly creating a dead-leg or an air pocket requiring additional maintenance and leading to a less desirable installation solution.
  2. A duct may pass close to an electrical tray but out of clash detection range. When the duct passes below or to the side there is no issue, when it runs above it will prevent the loading of that tray and will not be a practical coordination solution.

We will take account of all aspects of the coordination, and either resolve any anomalies, or refer them back to your design team.
