In a world of digital twins, a white model on a table still catches the clashes and access problems nobody saw on screen.
The table test
Every major plant we design passes through a physical model review. Operators, maintenance teams and the client stand around it, and the questions change. Can I get a forklift here? Where does the crane land? Which valve do I close first?
What models catch
On our last ten projects, model reviews caught an average of 14 access and maintenance issues that had survived the 3D design review. Every one of them is cheaper to fix in foam than in steel.
Digital and physical
The model doesn't replace the digital twin. It complements it. The twin answers what, and the model makes people ask how.
