After verifying correctness and organization, the final stage of a model audit looks at how the pieces work together. Even a model that seems clean in isolation can hide conflicts between disciplines. This is where clash detection and coordination come in.
Common issues include:
Audits perform clash detection to uncover these issues before they show up in the field. It’s much cheaper to fix a duct path in the model than to cut into a beam or reroute on site causing unknown downstream issues.
Clashes aren’t just physical. They can be informational too:
Audits reconcile these discrepancies and flag them for coordination.
The Goal: A Single Source of Truth
At the end of the day, BIM is supposed to be the central, reliable reference for all project stakeholders. If the drawings say one thing and the model another, trust breaks down. The audit ensures conflicts are identified and resolved so everyone works from the same playbook.
The final step of a model audit is all about integration. By catching clashes and reconciling conflicting data, the audit strengthens the model’s role as a single source of truth. This ensures smoother coordination, fewer RFIs, and a construction process that matches the plan.
Throughout the series we highlighted some of the specific tasks, but also why. The purpose is of an audit is not just to ensure we have a clean consistent filing system, but also to ensure the model has real value.
If the teams responsible for construction and ultimately operations and maintenance don't see value in the process, the time put into the details of the model loses it's value, and trust.
Therefore, the value of a clean model is not to prove your own skills, but to prove its value as it moves to the next stage in the process.
