Brief definition
A bill of quantities (BoQ) under VOB subdivides services into headings and line items with item numbers. Each line references quantities, units, and descriptions — the basis for bids and settlement.
Typical structure
| Level | Content |
|---|---|
| Heading | Trade / cost group / construction section |
| Line item | Individual service with unit (m, m², pcs) |
| Long text | Description per STLB-Bau or office standard |
Normraum relevance
Every BoQ line item needs a traceable quantity. Normraum supplies the geometry for it from the as-built plan: rooms with area under DIN 277, detected walls, doors and windows – every item with its source reference in the original plan and a confidence score. Heading structure, item numbers and service descriptions stay with the planner; the check log is the evidence of where the figure comes from.
