Brief definition
AI quantity surveying denotes the use of software to support quantity take-off from drawings. Serious B2B solutions for architecture and construction estimating separate geometry (measurable, verifiable) from language models (standards, text, explanations).
Risk of uncontrolled LLM arithmetic
Pure language models can hallucinate areas and lengths. For bills of quantities and settlement, a deterministic audit trail is mandatory — especially in German regulatory contexts (VOB, DIN 276, WoFlV).
AIGO relevance
AIGO derives quantities directly from the drawing and supplies standards references with source citations. Calculations are deterministic and auditable; processing is GDPR-compliant in the EU.
