Brief definition
DIN 276 structures building costs into cost groups (KG) — from site (200) through building structures (300) and technical installations (400) to project ancillary costs (700). The system enables comparable cost and fee planning.
Typical groups in early design
| KG | Focus |
|---|---|
| 300 | Building structures, take-off from drawings |
| 400 | Technical installations |
| 500 | External works |
| 700 | Fees, ancillary costs |
AIGO relevance
AIGO focuses on verifiable quantity take-off from 2D PDFs for geometry-driven groups (esp. 300, 400, 500). Exports are structured for BoQ and cost-group assignment, deterministic and GDPR-compliant in the EU.
