Brief definition
Cost group 200 (KG 200) under DIN 276 captures site / land costs — in particular acquisition or use rights and site-related preparatory measures, insofar as assigned to this group.
Relevance for quantity take-off and BoQ
KG 200 is typically not geometry-driven like KG 300/400. For total costs and feasibility studies it is nevertheless linked to building and technical groups. Quantity take-off from drawings rarely affects KG 200 directly.
AIGO relevance
AIGO focuses on verifiable geometry from 2D PDFs for building and technical cost groups. Land costs remain in your calculation; AIGO exports can be mapped into overall DIN 276 project structures.
