Do not lean against the building

In the TBC world, the model is not a foothold.

Even slight pressure can misalign walls, roofs, glass panels, balconies, signs, facade elements, or small decorative details. What seems like a harmless gesture can turn into a shift that is hard to notice right away, but becomes obvious as soon as you look at the entire building.

A true TBC operator works alongside the model, not above the model.
It positions itself carefully, maintains the correct distance, and uses suitable tools to reach the most difficult spots without putting weight on the structure.

Cleaning must respect the balance of the construction, not put it to the test.

Because of this, every TBC intervention starts with a simple rule: the model is observed, protected, and cleaned.
It is never used as support.

TBC Rule: Light hands, right tools, zero weight on the structure.
