Infrastructure drawings are precise, but they are not always easy for every stakeholder to interpret. Visualisation should clarify level changes, movement and the relationship between engineered systems and their surroundings.
The most useful views answer a specific review question. A traffic view, an underpass level view and a civic-context view may each require different framing and information density.
Accuracy is especially important in public-facing work because the visuals may shape how a project is understood well before construction begins.
