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 |
Normraum relevance
For cost planning under DIN 276, Normraum supplies the reference quantities from the as-built plan: areas per room under DIN 277, which cost indicators refer to, plus the detected walls, doors and windows with their source reference. Assignment to cost groups stays with the planner; the check log documents where every figure comes from.
