The blind leading the blind – how to misunderstand the collision search

I love it when an architect or investor proclaims with sparkling eyes that their project is in BIM and that the collision search is the guarantee that the design is good.

This reminds me of the blind driving prank of Rémi Gaillard, a scandalous representative of French absurdist humor.

This inefficiency leads to the fact that a good part of Hungarian BIM projects resembles a disco accident, which makes the neck of the construction bleed.

It is a fundamental mistake to think that a design is BIM or good quality if the architect and the designers “blindly” build models independently, then fit them together and run a clash detection.

I try to be graphic.

This is as absurd as boasting that

So let’s just say that for a major project, all-phase planning is effective – when planners design a model and see who is doing what in near real-time. That way, they don’t create clashes in the plan – just as we normally drive with our eyes open and avoid obstacles.

And clash detection is a quality control tool, like a seat belt, that helps when someone has been inattentive and made a mistake.
