Brief definition
Cost group 500 (KG 500) under DIN 276 comprises external works — including terrain, outdoor access, planting, and open-space-related building works, insofar as not assigned to other groups.
Relevance for quantity take-off and BoQ
Site plans and external area drawings provide areas and lengths (paths, surfaces, fencing). Calibrated scales and documented geometry sources are decisive for BoQ items.
AIGO relevance
AIGO processes 2D PDFs including site and external area drawings: deterministic take-off after scale calibration, structured export for assignment to KG 500 and adjacent groups.
