Why Clashes Exist in BIM At All with Rubens Lage Lopes

Clash detection is a symptom, not a fix. Inside BIM coordination rules, ISO 19650 in the real world, and AI that turns clashes into cost.

Walk into any occupied building with an exposed ceiling and you will find zero clashes. Open the model of that same building and you will find thousands. Physics stops two objects occupying the same space, but our software does not, and the industry has quietly accepted that as normal for thirty years.

Rubens Lage Lopes, BIM Information Manager at the Grangegorman Development Agency, has spent more than twenty years in construction across Brazil and Ireland, and now sits on the client side of one of the largest campus redevelopments in Dublin. The conversation starts from a question he posted on LinkedIn, why clashes exist in BIM at all, and follows it into coordination, information management and where AI genuinely earns its place.

Rubens makes the case that coordination is a consequence of the information agreed before anyone models anything, and that the procurement route shapes the outcome long before the first clash appears.

Useful listening for anyone tired of chasing clashes they could have prevented.
