Brief definition
AI surveying denotes software that detects rooms, walls and openings in as-built plans – scan, PDF, photo – and derives areas from them. Serious solutions separate detection (AI reads the plan) from calculation (geometry computes deterministically) and state per item how certain the detection was.
What an AI survey delivers – and what it does not
It delivers a checked working basis in minutes: a room book with the area per room under the selected norm and a check log. It does not replace an on-site survey: old plans deviate from the building as built, and what the plan does not show – heights, fit-out condition, later alterations – no software can read from it. Pure language models are unsuitable for areas: they estimate instead of calculating. Evidence under WoFlV, DIN 277 or VOB needs a deterministic audit trail.
Normraum relevance
Normraum works on this principle: AI detects walls, rooms, doors and windows in the as-built plan, a deterministic geometry engine calculates the areas under DIN 277 or WoFlV, and every room carries a confidence score and source reference in the check log. Uncertain detections and incomplete dimension chains are flagged – that is where a survey is needed; Normraum does not replace it.
